- ideal logic No hot water heating on Blocked plate heat exchanger. Water cold, warm or fluctuating.
Radiators get hot when taps are being used.
In the video you'll see how easy it is to make a mistake, but also how prepared you need to be to fix it and knowing being a good gas #engineer and #plumber isn't just about fixing it first time, it's about knowing how to deal with mistakes, leaks and other dangerous situations quickly and effectively with minimal damage.
Nobody can fix things without a mistake.

Bruv... it takes guts and sacrifice to continue to film this to educate people whilst forsaking the requirements to make a straightforward job so tricky.
The fact you had to run downstairs to isolate the mains whilst having no means to control the situation and still continue to film... I salute you...
99% of us.. me included would of after the 1st attempt, thought sod it... I'll use both hands to do it then film and explain..
Your a star brother...
Thank you.👍🏾
I appreciate it, hopefully 1 day I'll improve and be up there with top RUclips boys 😂 thanks
I can’t see , you rubbed enough silicone on those washers, apart from anything else, it’s spot on , brother 😂
Well done matey working on boilers is nothing but a challenge these days
Thanks for sharing
A very brave video...with phone in one hand and the job in other ..running down the staircase and dealing with a leak on a new fitted plate...really helpful video.
Any more you have how to change diverter valve and prv on these
Thank you for sharing
I do this every 2 years but isolate the water from in the kitchen and drain. I use Knockout industrial strength liquid unblocker that does the trick and gets it clean after leaving overnight.Never had to replace the unit.
Thanks for the real time information.👍
Top video buddy
Thanks 👍 sub for more
very good explanation 👏
Thanks for the support
I dont uderstand why you did,nt isolate the cold main under the boiler?
Can't recall didn't work or wasn't installed I think it was bodged in
Could you not have isolated cold under boiler?
No it couldn't
@@mendyourhome I changed a hx plate on a Worcester greenstar erp, I drained the heating system, hot and cold taps and took out the pressure from the Expansion vessel and isolated return, flow and cold under the boiler. When I opened the screw on the hx plate, quite a lot of water was still coming out, so I let it drain out slowly as I didn't want the water to damage any other parts, ESP the electrics.
What could I have done differenly to make sure all the water is out regardless of which boiler is being worked on?
Thanks.
older boilers say ZJ think this one manufactured in 2004 installed in 2012 heat exchanger cracked in 2024 11 year old.
Can't you just shut the mains off at the boiler with the cold feed valve that's under the boiler that's how I isolate ideals normally that way would off saved you running outside
I couldn't isolate as normal. I might of explained it in the video, either it didn't work or wasn't an isolation. 😂 But thanks for the comment. I'd appreciate a sub. I have loads more videos also heat pump install coming soon
What would be an acceptable price for this job? I've got the exact same boiler and the same issue. Not covered by boiler plan as limescale buildup (hard water area)
Dirt in the siphon water trap isnt indication of dirt in the heating system as it is only condensate and products of combustion.
5:09 to skip drain down and straight to removing the parts.
Hi there just a quick one what was the reason you changed the plate heat exchanger I have a l3 fault on my boiler and I get next to no flow with 2 taps running I’m assuming the plate heat exchanger is blocked
Fan matw
What grease silicone do you use?
1) servisol Silicone Grease 2) Regin Silicone Grease 3) Polypipe silicone grease (this 1 i also use for some plumbing)
Whats next if plate heat exchanger has be cleaned or renewed but still no hot water and no fault codes appearing.
Diverter valve
@mendyourhome
The boiler guy has checked the diverter valve by adjusting flow to check but has not taken it apart. So far, new plate heat exchanger fitted, checked turbine, replaced fan, gas valve, switches, and checked gas flow rate at gas meter. The hot water dial is at max hot, but we are only getting lukewarm water from taps. CH radiators are piping hot.
No fault codes appearing on boiler.
Why did the heat exchanger become blocked when the system had a magnetic filter fitted?
This is a secondary heat exchanger. It's likely to be blocked on the domestic hot water side which is caused by lime scale and other minerals from poor water quality ie hard water coming on from the mains although It can still be blocked on the heat side from sludge as a magnetic filter will not catch everything.
Magnetic filters mainly capture magnetic particles, but not everything. Also this is a plate heat exchanger limescale is a common culprit on the hot water side being blocked. Because the plates are so tightly crammed in it not 1 blockage it's a slow build up over time, like a Dam that keep collecting more debris.
Why didn’t you isolate it under the boiler also could of just cleaned that plate out if it was blocked with acid unless it’s split in which case pressure would of risen on gauge
It was year ago, but i believe they didn't work or hadn't been fitted
Mate the filling loop is the isolation keep the return shut and open the cold it isolates the flow into boiler it’s a 3way valve type are you a new engineer fumbled around abit if your flows getting hot it’s a diverter issue nothing to do with a plate please don’t give wrong info to people on here so there fucking around with their boilers
Sink tap is nicely sealed to the worktop. SMH………..I know that wasn’t you.
first drain the water then open hot plate
That looks brand new so didn't have a power flush...
Maybe or not well maintained
