This is such an awesome video - came to it after seeing your other video about descaling and risk of breaking the machine (which of course I had already done). I'm encouraged to get my hands dirty now and try to save my machine!
Just replaced my O-Rings. Dropped 3 clips but had three replacements. Solution was to tie a piece of dental floss to the clips, then just cut it off afterwards. Problem solved. One of the new blue large o-rings was very hard to fit, but got there in the end. Thanks for the videos.
yes i have since found out it's much easier to get the blue ones on if you leave if half way down the shaft when you press it in. This is how Breville ships them out with new probes, so i guess that's why
This is awesome. The speed, the dialog and the visuals. My Breville Oracle Touch started tripping the circuit and sure enough it looks like all of the o-rings are busted. I've ordered the parts and will try the repair. Thanks for putting this together!
I replaced my rings 2 years ago, and made the mistake of not knowing that some of them needed 2 o-rings and made a new leak rather than fixing the one leak! I figured it out quickly, but seeing im about to do a repair on the steam wand value, i was happy to stumble onto your video as a referesher. Thanks for sharing!
Hey man, really appreciate this. I found a hissing sound from my Sage Dual Boiler and managed to replace the O-rings after watching your videos correctly diagnosing it. I don't know how much money you saved me but it's a lot more than I spent to get new O-rings and bits. Thanks!
A couple of suggestions as i've just done this task on my machine over the past couple of days. Edit the video title to mention O-rings as this didn't come up in search and it's a pity because it's a very clear one. I think as this concentrates on prevention rather than a full O-ring job, maybe that's why it doesn't mention the 5mmx2mmx1.5mm white silicone O rings at the bottom of the probes but those were the ones that mine was leaking from, not the blue O rings at the top. I've still got small leaks in the filler tube fittings but waiting on parts for those :)
Thanks I will change the title. I didn't mention the probe orings as i was going to do a seperate video just on probes at some point, and yes this is a general prevention video so didn't want to get too down in the weeds with the not so common stuff. thanks
Thankyou @Brevtech , my white probe washers had failed (2 of them on steam boiler), symptom was noise and (very) hot top. Inspection showed probes were "loose". Machine only been in use under a year. Watched the video & purchased kit from you, fixed it. love your work. Changed white and blue on all 3 steam probes. coffee is on again. 6 monthly check seems excessive, but my last machine rusted out inside (after 10 years & 2 professional services) so 6 mths seems like a good idea now. :) Suggestion... include a few spare washers (white, blue & red) rather than an exact number. The rescue kit includes a lot of stuff to cover most? common fixes. Would love if it did more than 1 o-ring service. (Mine has mix of old and new compression fittings on steam boiler)
@@BrevTech It certainly fixed my problem, which is awesome, delivery was fast and you were easy to deal with, a perfect supplier. :) I used 3 whites and 3 blues straight off for steam boiler as the probes were loose (inner part/ white), you could feel all 3 "rattled", so orings were shot. Maybe I was just lucky to get crapy original rings.
Great video I am a breville owner started with the BBE about 3 years for a and I have had the BDB for about 1 year great machines I dont care what anybody says.. I will subscribe keep up with the videos..
While working on fixing my needle valve problem (which causes the hot water spout to drip water, and can affect brew pressure) I came across this video and literally just watched it yesterday. Low and behold I discovered not 1 leak but 2 and evidence they had been there for a while.....sigh. Problem Avoidance versus Problem Reaction - I wish I had watched this earlier and taken the time to change those out ever other year.... And why Why WHY don't o-ring kits include the retention clips???? I dropped 2 down into the boiler nether regions and lost forever....made replacements out of stainless steel paper clips but seriously....silicone grease on my fingers + tiny clips = gone baby gone. Thank you for the great video....and 920XL owners, don't be like me - crack that lid and take a look once a year.
Thank you! This helped a lot! One question though, is the newer compression fitting backwards compatible? As in, can it be installed on machines that have the older fittings?
Thankyou! Do you mean can you buy a new boiler and install it onto your older machine? Yes you can, but you'll need to buy all the conversion tubes too to convert from your new steam boiler to your old style coffee boiler. You'll also need to buy the newer NTC like this: www.ebay.com.au/itm/204587634550 all in all, quite an expense!
You think you can do a future video on Descaling and things that can happen and how to fix them? There are tons of people like myself having issues after descaling where a boiler doesn't fill up. Is there a way to clean the boilers without having the solution pass through small piping?
This video was really helpful, thank you. In the end I replaced the o-rings, triac board, and thermo probes as one of the thermo probes was leaking through the inside of the probe! This also fixed the air leak which was causing the machine to have a 10-15 second delay before anything would happen - I now get pre-infusion immediately on pressing the button. One problem I do seem to still have, there is water collecting underneath the left hand side of the drip tray ie. not under the boilers - any ideas about what to check for this?
there are a couple of tubes run down there. One is dirty water from the coffee solenoid and the other is from the vac valve. It will be the vac valve (centre of the steam boiler) that is leaking. (white one) Its a bs008 from memory, but you might be able to get by with a spare 007 if you have some left over.
@@BrevTech thanks! Actually, the water il finding under the drip tray is dirty so based on your explanation I’m thinking it relates to the solenoid line?
Very helpful channel, thanks. My BES920xl is leaking over the top of the portafilter. I'll try replacing the silicone gasket first, although doesn't look worn. There appears to be an area of wear on the plastic collar inside the grouphead. I'm having trouble finding a replacement collar - do you have a source?
Common problem. EBay has plenty here in OZ. Not sure if they ship internationally tho. Search for bes920/980 collar. Make sure you get the right version as there are a few.
Just stumbled on your very informative channel. My dual boiler is about 4 years old and apart from the regular clean, and one descale I havent been game to do anything more involved. Lately I'm finding myself having to coarse up the grind so the pump wouldnt stop right after preinfusion and i could still get a half decent shot. If I wanted to do a complete overhaul of my machine would you have a list of parts I would need? Thanks in advance.
The best advice I can give anyone that has a used dual boiler more than a few years old, is to get the dual boiler survival kit. There is a link in the description.
Question; I have a hard time putting the probes back with new o-rings; the probes don't go in deep enough. Could this be due to scale at the probes openings? I am sure I have the correct sizes ;-).
Hello, I just bought a used, 8 months old BDB and having slight problem after powering it on first time at home. While trying it at the owners house, it worked fine. Now at home it gurgles whenever I turn water dispensing on. I can see air pockets traveling back and forth in the line going from hx to brew boiler. Steam works fine. Water dispensing seems a bit inconsistent at the beginning of preinfusion however pressure builds up fine. Temperature is also stable. Seems a bit strange that there would be a leak on one of the connections to the hx or brew boiler. And if so, would the pressure be going down while using blind basket? Pump is also working fine. Have set preinfusion on the lowest pressure and it's working normaly.
All these machines gurgle to some extent from what i've found, its when it become constant gurgling that you might have a problem. Yours could be a leak on the HX line, but more likely its just water being cooked in the HX to 130c. The best tip someone gave me to check for leaks (that i didn't know before making this video) is to put a plastic tube to you ear and use it like a stethescope on each of the ports. You'll be able to hear leaks that you cannot see. I'm going to add this tip to the description actually.
On the steam boiler, I’m struggling to get one of the hoses out after taking off the retaining clip. I’ve put plenty of force behind it and it just won’t budge. Any thoughts?
They can be extremely difficult, and the pipes damage easily. if it isn't leaking then i'd be inclined to leave it. I've had some stuck like this that i've had to drill out before. Then i've had to flush out the swarf from the boiler
Most of the videos are on the steam boiler. and this one is maintenance but what about the other boiler? is there any maintenance with o rings for it as well? or does this big steam boiler work in conjunction with the other boiler? I am new at this so forgive the maybe ignorant question.
There are the same orings on the coffee boiler but as it runs at a lower temp they tend to last at least twice as long. You can transfer the same maintenance process from the steam boiler to the coffee boiler
I saw where the leak was and changed the o rings but it’s still tipping the breaker They are giving me a 40% discount on a new one ? Should I just buy a new one or is that something that can be fixed easily
I would be very tempted to just go with the new one. If your breaker is tripping without any leaks then in my experience, it usually means the element has damaged insulation, which would require a whole new steam boiler. Those are very expensive and unless you are doing the repair yourself, would cost half the price of a new machine.
Thank you I actually found another leaking o ring on the side I was about to change it but dropped the cutter clip, what size clip are these? They are not available online ! Thanks
Can you say more about older machines? You mentioned something about compression joints lasting longer than O rings. What "generations" has The Double Boiler been through? How can they be identified? Thanks
It's been through a few changes since 2011. The most notable were adding the boiler drain ports when going from the BES900 to the BES920. This is visible by the rubber cover on the right above the drip tray. There were some other changes inside on the steam pump and group collar too. Then compression fittings on the heat exchange ports were added next (not sure of exact year) then in 2022 they changed them all over to the newer type
The orings do need changing on those, but more often than not the parts to fail on those before orings are usually the solenoids. The elbow connectors too. Your issue certainly sounds like a solenoid isn't closing properly - i'd say it is the 3-way one. You can sometimes get lucky by cleaning them but most of the time they'll need replacing.
@@BrevTech thanks. How easy is that to do & more importantly how easy is it to get the parts? I tried to get the machine serviced a while back. Sage wanted £140+ and none of the local coffee machine service folk would touch it because they couldn't get parts.
It's about a 30min job and not very difficult. About 8 screws to remove the lid and back case, then you can get to it. There are plenty of YT guides, It's on my todo list to make one too. Those solenoids are very easy to get over here in OZ but ebay would be the best bet. Here's one that ships to the UK: www.ebay.com.au/itm/386958079259
My Duo Temp Pro (BES 810 BSS) would have water coming out from places other than the tip of the steam wand. I'm guessing it needs the same service shown in this video. Does it have the same boiler?
@@BrevTech Thanks! The sputtering is more evident when using the wand for hot water, although not that bad. Other than that it works normally esp when steaming. Is this something that can wait or should be fixed asap?
@@anitu-oy9qp any water inside should be looked at asap. It might not be economical to pay someone to fix it - given the price, so I would take the lid off and run it to see if you can narrow down the problem. It might just be something quite simple to repair
you reffer to gurgling and O-rings. i have the problem that when i start a shot it gurgles and then the -pump starts up during pre-infusion. do you have any ideas on this one?
@@BrevTech net when it gurgles. the pump starts at about 5-7 seconds. Sometimes i just run water then hit the shot button. pump was replaced only anout 18 months ago. machine does one coffe in the morning on average
@@borisjankovic3525 i'll bet it needs another new pump i'm afraid. Classic sign when you lose preinfusion. They supposed to last for 5,000 coffees, but i have replaced nearly new ones before. you can get away with just replacing the oring inside if you want to save some $$ something like this: www.ebay.com.au/itm/124499370149
Funny you should say that. When I replaced it I accidentally purchased a pump with a brass top. It was 24v dc instead of 240v ac. I kept the internals as a spare just in case. Looks like it’s time to install it
Hi there, do you have any suggestions on what to use instead of the hose clips? I was replacing the O-Rings on mine and lost one of them in the depths of my machine.
@BrevTech Thanks for the response! I initially went to the official Breville part online but the cost plus shipping was astronomical. Luckily I managed to source something similar on Amazon.
Hello, I've just stumbled across this and I have an issue with gurgling at idle on my bes920, and the temperature keeps increasing. From what I can tell there is an air leak somewhere. Do you know how i could fix this? If i draw water up as its heating up, i can quickly pull a shot at temp, but will only be around 7bar, then the gurgling returns and i can't use it any more. Thanks in advance!
The temp increase is a faulty triac board. You'll likely find you have a leak inside that is letting out steam onto the triac board. I would turn it off at the wall until it's fixed. When the triac board isn't working it will constantly heat up the boiler which can often cause the thermal fuse to pop. I have other videos covering the triac board if you are handy. Otherwise get it serviced asap. thanks
@@BrevTech Sorry I should have been more specific - the temperature will rise until it reaches 93 degrees, then it will sit there very steady. Sometimes (more often than not) after a pulling a mediocre shot, the screen starts flashing and the temperature will begin to rise, and the gurgling starts. With the lid off, I can see air bubbles going up and down some of the pipes. Also the steam wand constantly drips (even when off). Do you still think it's the triac board? Thanks for responding
@@kilkVal it’s hard to say as it sounds like you have more than one problem. It sounds like it needs a good overall service. Orings, pump and Steam valve service would be my next steps. So the temp doesn’t go over 93c at all?
@@BrevTech Maybe so, I did buy it 2nd hand and it's been pretty decent so far until recently. It does exceed 93c after awhile, but not immediately, as in it doesnt just continue to rise. From a post on a forum it seems like there is air in (i want to say the heat exchange) and a temperature thing in there which is supposed to be submerged is now exposed to the air, causing it to miscalculate and heat up - but unfortunately they didn't really go into a fix outside of "there is probably air getting into your system"
The gurgling can occur when air gets into the coffee line, which is usually down to either a leak on the heat exchanger ports or a faulty pump not providing enough water to the coffee boiler. Another reason, is that your triac board is overheating the boiler. I think you could have a mix of both - given you said you had poor pressure. Take a look at my other video about the self check menu. This will show you how to measure the temps of the 3 boilers and you'll find out which one is at fault. Wait for the machine to go over 93c, then enter the menu to see. Not trying to sell you anything, but if you are wanting to fix the machine yourself, then something like the survival kit I sell would suit you, as i think you're going to need quite a lot of the parts from it.
I didn't catch where you applied the silicone grease.. the video just showed you replacing the O-rings.. and then a few seconds later you mentioned silicone grease with a photo, but not where you apply it.
Smear over the orings. It’s so they seat easily and don’t get nicked or torn. You don’t need much. A toothpaste sized amount would go around all of them
Let’s be honest, I pay 3k to get a machine and it breaks down in 6 months and every 6 months I must replace and maintain a piece of the machine that if I touch, voids the warranty. Mate, what happened to quality, paying what you get for. It’s bloody 3 thousand dollars, I can buy the biggest fridge with that which doesn’t need maintenance for 3-5 years.
i agree. but, they've (finally) made massive improvements in the most recent model. Not sure of the exact release date, but if you bought yours after mid-late 2022 then there's a good chance it is and you shouldn't get this leaking problem nearly as much. This video is really aimed at those with the older model. i'll update the description. thanks
@@AlxVKytc I've had my Dual Boiler for close on 10 years. Haven't had a single issue until recently. Admittedly, I am pretty particular about the quality of the water I use, backflushing every day, and running a cleaning cycle weekly. But this is pretty similar to what baristas do with their 10's-of-thousand dollar machines daily. Your car is probably a better comparison than a fridge. You service your car at regular intervals if you want it to keep running smoothly. Same can be said for all coffee machines being worked daily, even the cafe quality machines.
@DuaneJs I get what you're saying, but coming from personal experience and the thousands of people who have the exact same issue clearly indicates there is either an engineering issue or quality issue. I'm a handyman, part-time mechanic, experienced technician and electrician, so I know a thing about cars, fridges and espresso machines, people are better off buying the breville that are equipped with the thermojet, less fuss. Overall it's an id.10t issue.

My breville dual boiler is tipping the breaker , do you think that’s because of the o rings.
it could be either a really large leak or damaged steam boiler. Check my steam boiler repair video to learn how to measure it. Good luck!

Those solenoids are very easy to get over here in OZ but ebay would be the best bet. Here's one that ships to the UK: www.ebay.com.au/itm/386958079259
My Duo Temp Pro (BES 810 BSS) would have water coming out from places other than the tip of the steam wand. I'm guessing it needs the same service shown in this video. Does it have the same boiler?
No that has a small thermoblock boiler. On those it’s more likely a leaky oring or split connector near the solenoid
@@BrevTech Thanks! The sputtering is more evident when using the wand for hot water, although not that bad. Other than that it works normally esp when steaming. Is this something that can wait or should be fixed asap?
@@anitu-oy9qp any water inside should be looked at asap. It might not be economical to pay someone to fix it - given the price, so I would take the lid off and run it to see if you can narrow down the problem. It might just be something quite simple to repair
you reffer to gurgling and O-rings. i have the problem that when i start a shot it gurgles and then the -pump starts up during pre-infusion. do you have any ideas on this one?
Is water coming out during pre infusion?
@@BrevTech net when it gurgles. the pump starts at about 5-7 seconds. Sometimes i just run water then hit the shot button. pump was replaced only anout 18 months ago. machine does one coffe in the morning on average
@@borisjankovic3525 i'll bet it needs another new pump i'm afraid. Classic sign when you lose preinfusion. They supposed to last for 5,000 coffees, but i have replaced nearly new ones before. you can get away with just replacing the oring inside if you want to save some $$ something like this: www.ebay.com.au/itm/124499370149
Funny you should say that. When I replaced it I accidentally purchased a pump with a brass top. It was 24v dc instead of 240v ac. I kept the internals as a spare just in case. Looks like it’s time to install it
Hi there, do you have any suggestions on what to use instead of the hose clips? I was replacing the O-Rings on mine and lost one of them in the depths of my machine.
You can buy them but I guess something like a small safety pin or paper clip would suffice
@BrevTech Thanks for the response! I initially went to the official Breville part online but the cost plus shipping was astronomical. Luckily I managed to source something similar on Amazon.
Hello, I've just stumbled across this and I have an issue with gurgling at idle on my bes920, and the temperature keeps increasing. From what I can tell there is an air leak somewhere. Do you know how i could fix this? If i draw water up as its heating up, i can quickly pull a shot at temp, but will only be around 7bar, then the gurgling returns and i can't use it any more. Thanks in advance!
The temp increase is a faulty triac board. You'll likely find you have a leak inside that is letting out steam onto the triac board. I would turn it off at the wall until it's fixed. When the triac board isn't working it will constantly heat up the boiler which can often cause the thermal fuse to pop. I have other videos covering the triac board if you are handy. Otherwise get it serviced asap. thanks
@@BrevTech Sorry I should have been more specific - the temperature will rise until it reaches 93 degrees, then it will sit there very steady. Sometimes (more often than not) after a pulling a mediocre shot, the screen starts flashing and the temperature will begin to rise, and the gurgling starts. With the lid off, I can see air bubbles going up and down some of the pipes. Also the steam wand constantly drips (even when off). Do you still think it's the triac board? Thanks for responding
@@kilkVal it’s hard to say as it sounds like you have more than one problem. It sounds like it needs a good overall service. Orings, pump and
Steam valve service would be my next steps. So the temp doesn’t go over 93c at all?
@@BrevTech Maybe so, I did buy it 2nd hand and it's been pretty decent so far until recently.
It does exceed 93c after awhile, but not immediately, as in it doesnt just continue to rise. From a post on a forum it seems like there is air in (i want to say the heat exchange) and a temperature thing in there which is supposed to be submerged is now exposed to the air, causing it to miscalculate and heat up - but unfortunately they didn't really go into a fix outside of "there is probably air getting into your system"
The gurgling can occur when air gets into the coffee line, which is usually down to either a leak on the heat exchanger ports or a faulty pump not providing enough water to the coffee boiler. Another reason, is that your triac board is overheating the boiler. I think you could have a mix of both - given you said you had poor pressure. Take a look at my other video about the self check menu. This will show you how to measure the temps of the 3 boilers and you'll find out which one is at fault. Wait for the machine to go over 93c, then enter the menu to see. Not trying to sell you anything, but if you are wanting to fix the machine yourself, then something like the survival kit I sell would suit you, as i think you're going to need quite a lot of the parts from it.
I didn't catch where you applied the silicone grease.. the video just showed you replacing the O-rings.. and then a few seconds later you mentioned silicone grease with a photo, but not where you apply it.
Smear over the orings. It’s so they seat easily and don’t get nicked or torn. You don’t need much. A toothpaste sized amount would go around all of them
I just got a dual boiler , so these common problems are gone and its updated or ? Thanks
New ones are much better.
Let’s be honest, I pay 3k to get a machine and it breaks down in 6 months and every 6 months I must replace and maintain a piece of the machine that if I touch, voids the warranty.
Mate, what happened to quality, paying what you get for. It’s bloody 3 thousand dollars, I can buy the biggest fridge with that which doesn’t need maintenance for 3-5 years.
i agree. but, they've (finally) made massive improvements in the most recent model. Not sure of the exact release date, but if you bought yours after mid-late 2022 then there's a good chance it is and you shouldn't get this leaking problem nearly as much. This video is really aimed at those with the older model. i'll update the description. thanks
@@BrevTech “Nearly as much”!!! Enough said.
@@AlxVKytc I've had my Dual Boiler for close on 10 years. Haven't had a single issue until recently. Admittedly, I am pretty particular about the quality of the water I use, backflushing every day, and running a cleaning cycle weekly. But this is pretty similar to what baristas do with their 10's-of-thousand dollar machines daily. Your car is probably a better comparison than a fridge. You service your car at regular intervals if you want it to keep running smoothly. Same can be said for all coffee machines being worked daily, even the cafe quality machines.
@DuaneJs I get what you're saying, but coming from personal experience and the thousands of people who have the exact same issue clearly indicates there is either an engineering issue or quality issue. I'm a handyman, part-time mechanic, experienced technician and electrician, so I know a thing about cars, fridges and espresso machines, people are better off buying the breville that are equipped with the thermojet, less fuss. Overall it's an id.10t issue.
@@AlxVKytc i have 2 of those Breville thermojet machines in for repair right now - with problems relating to the thermojet 😉
