The impeller gets jammed up so easy that I'm surprised they have not come up with a solution like a screen to prevent hair and debris from getting trapped in there.
My impeller is not blocked yet the robot has the same behavior. The rollers spin one direction easier than the other, however there are no obstructions on the track. Any ideas?
This happened to me. The next few power ON cycles, I spun the impeller forward and backward by hand AND moved the square piece that "aims" the water (just above the impeller) side to side gently to make sure it was moving freely. It has run several startups with no problem since :)
@@spungewurthy could you explain that in a little more detail. Does that mean you take it apart again and move the propeller by hand? I’m not sure how this works with a power on while you’re doing that. Sorry I’m just a little confused. Any clarification would be greatly appreciated.
@@spungewurthy mine did the same thing. I didn’t take mine apart, but just turning it on and off i was able to get it to run a few more times in full cycles but now it has stopped again so I’m gonna be tearing it apart tomorrow to see if the impeller is dirty
I was very disappointed to take my impeller out and find that it was spotless. I found a tiny acorn or pebble in one of the directional vanes that surround the impeller. I removed the 4 screws popped that little guy out (it fell in the lawn and was gone so I'm not sure what it was) and put it all back together. To my delight, my robot is back to cleaning! So while it was not this exact issue, it was very similar and I wanted to let other viewers to know to make sure those directional vanes surrounding the impeller are clear of any tiny bits of grit. Thank you!
i had the same problem, i was a click away from ordering a new control unit until i came across this video. took 5 minutes to fix. thanks a million guys!!!!
IF cleaning the impeller doesn't work, here's what I did in addition: The next few power ON cycles, I spun the impeller forward and backward by hand AND moved the square piece that "aims" the water (just above the impeller) side to side gently to make sure it was moving freely. It has run several startups with no problem since :)
Thank you so much! This video should be the first one that pops up when a search is done for an automatic pool cleaner starting then stopping! Thank you so much!
Thanks for this video. Looks like many people are having this problem. This is definitely a DESIGN FLAW! For my 10-year-old Dolphin DX3 I need to unscrew only 2 screws to clean the impeller. Maytronics is in the business for many decades and should fix this PROBLEM instead of keep on confusing the customers with many labels & covers. The customers should NOT have to get into the GUTS of the machine to fix this common issue.
Great Video! Definitely earned a subscriber, had a little piece of plastic that was jammed and preventing the impeller from spinning. Saved me a lot of money Thank You!
I did as you said a month ago and it worked. However, it stopped working again even after cleaning it out. It goes for around 30 seconds and then turns off. Please- any further suggestions? Greatly appreciate it.
My Dolphin DX4 moves about 3-4 feet and stops. I checked the impeller and it was clean. I replaced the impeller anyway and it still only moved about 3-4 feet and stops.
Worked perfectly. Thanks for saving me $150 and a trip to the pool store. Why Matt Tronics doesn’t include videos like this with their FAQs is beyond me. Thanks again.
Thank you! Our “Lil dude” was doing same thing and I just cleaned the fan area with my fingers and he was good to go after doing same start/stop. He’s been picking up pine needles and the ladies’ long hair which tangled up the fan. Didn’t wanna risk breaking the waterproof seal. He’s happy to be back to work now 😂 What an amazing little machine. Was gonna try to find an expensive replacement on Black Friday, but saved a lot of money. Thanks again!
There isn't any water proof seal in the areas where he is servicing in this video. The w/p seal is in the housing that holds the motor/board, which is under the impeller shaft.
I just opend up the motor unit and pulled the impellar motor out. Its filled with black soot, smells burnt and difficult to turn by hand. New one on Ebay for $115. Has anyone went this route before?
I just did…..replaced the impeller motor…it had carbon sitting in its well. For sure the carbon motor brushes are worn out. Ordered a reman on eBay. Just installed it…still does the same thing. I check it has 30 volts from the power supply. A little disappointed it still does it.
While waiting for Maytronics to contact me about my Dolphin Explorer 20 that would travel 2 feet before shutting down, I found your video and followed your instructions. I found that a very small amount of hair wrapped around the impeller was the culprit. Thanks again for taking the time to make this video!
Cleaned the impeller, there was hair and pine needles clogging it up. But this did not resolve the issue. It still is only moving forward about a foot then stops. Any other ideas?
My impeller was clean also, it runs great actually, and is churning up the water quite well. But the cleaner is still running only a few minutes then stops.
Mine is doing the exact same thing. Just bought it a couple days ago. Thought I got a bad one and was going to return it. I’m definitely going to try this. Thanks for the video!
If impeller is clean and spins freely. Try running it upside down on a bench. Then if it continues to run. Put it back in the water. I stripped mine down, cleaned it all out (it was fine). Bearings are fine. It’s a few years old and needs brushes for the main DC pump motor - but you can’t buy them from Maytronics which is a scam. They will only sell you an entire new motor. Brushes are a consumable part. Anywho. Put it all back together and it only ran a few seconds still…. Ran it upside down (perhaps a recovery maneuver?. And it’s run ever since. Still needs brushes soon though (before it destroys the motor from brushes running out).
Thank you so much! You just saved me hundreds of dollars at the pool store! My impeller had long hair twisted around it into a knot, which thanks to you and your clear directions, I cleaned off. And now my Dolphin pool vac is working!!! Thank you! Thank you! Thank you!!!
My dolphin run through the self test by moving forward, moving back, and running the fan. After that, it will not move. The impeller has been checked and it is clear. The basket has been emptied. Any suggestions?
If the fan is missing fins the machine also stops because the fan needs resistance to make the machine think its under water, to work propperly, cost 4 euro
Thank you for the video. I wish this reply may help someone else out. The propellor was clear. After checking the belts, realized my drive gear wheel was hopping around out of balance. This created a start and stop effect under a normal cleaning cycle. The small gear output of the motor was binding on the drive wheel. I swapped the left drive wheel for the right drive wheel. Cleaner is back in business. Be sure to take a close look at the gear and wheel play after removing the track belts. Placing an order for a new wheel. Device is cleaning like a champ. Cheers!
Someone gave me their dx4 proteus I put it in the water , it moved around but doesn’t pick up debris. Do you know where I should start to troubleshoot?
Same issue. Everything clean. Took the main housing apart and there was water inside of it. The control board had mineral build up. Tried to clean it up and no success. At this point I think I need a new board the motors seem to be working fine.
Update/solution!!! I started having this issue non stop. So much debris in the top part and outside of the basket. Turns out my rapid drain flap was missing! (The black flap between the wheels and robot). It prev came off and I thought I reconnected but apparently didn't, found it laying on side of house. To reconnect you have to use pliers to pull knotches through. It's working amazing now!!
I did this. Cleaned impeller and it made it work for two minutes instead of three seconds. Any ideas why it would now stop with a clean impeller after two minutes? I will add that the blue cord has a break in it
I’ve got the same problem (the dolphin do the same), but it’s clean!? The only way it works is leaving without the black piece (I guess it’s a piece that makes the robot rotate)…then, IT WORKS !?!😳 Message: overload propeller/Reset robot Ok … Not always the reset works!?! If I use the robot manually (remote), it’s the only way that it works with all the pieces…!?… I’ve tried everything: do you know any solution? Thanks!
THANK YOU, THANK YOU, THANK YOU! I was dreading hauling my Dolphin S300 in for service. It was reporting a comm error but that's because a pine needle jammed the impeller and after a time-out period (I assume), it reported a communication error - buts that's because after it dies and becomes not responsive, the control assumes its a comm error. So THANKS AGAIN for posting and solving my problem!!!!
6 month old Quantum… it was doing the same thing, checking showed impeller clean…. I put it back in the water and it’s up and running. Perhaps it reset after being unplugged? Anyway, thanks for the clear and constructive video on Dolphin maintenance… Cheers
Hey Bro, would you be able to help me? The left belt of my robot is not running. only one side goes forward and backwards, the other side stay still, so it wont clean. Do you think its a gear issue?
My Dolphin PS Triton does this where it won't pass the self test. The impeller is clean and there is no debris. Sometimes it works after i take it out of the water and put it back in but it's very hit or miss. The gears and track are fine so maybe its a motor issue. It i do the upside down test it works occasionally as well.
Thank you very much from Australia. my trusted pool guy charged me $270 for the same job four weeks ago and it happened again with all wifie/s hair tangled around the fan lol
I just disassembled my DX4, and there was ablut 1/4 cup of water inside the motor/board housing. No wonder it doesn't move, and the blue light is solid. The guy at my local Leslie's is going on vacation, so I'm not sure where to buy the parts. It was purchased 4/19/20, so it's "juuuuusssstttt outside of the 24 month warranty." We had the control/power unit replaced about 6 months after I initially purchased it. I'm not sure it is as robust as our previous Maytronics pool bot. I don't remember the nomenclature, but it had the bag under it, and had 80's esque pastel coloring. Unfortunately the replacement parts on it were hard to find, so after 3-4 years of my second hand use (it came with the house when we bought it.), I broke down and bought this new one. This new one is designed a lot better as the top load basket is easier to clean and the daily timer is better. But to me, the inside/working parts seemed to be better quality.
That was very helpful. I have seen a number of videos that simply showed how to clear the impeller from above. We have four trees behind the pool and lots of palms that shed those little wiry threads. Thanks!
I have a t55i brand new. I just wanted to make sure that the power supply is working so i did a outside off water test but for some reason my dolphin didn’t stop running it did the cycle and pause then start running again is this normal??
This was the EXACT problem I encountered today (after several cycles picking up winter debris from the bottom). The instructions took me 15 minutes to fix our "Little Geek". Debris plant "needles" had wrapped up the impeller like weeder whacker line. 5 minutes to clean out. "Little Geek" back in business! Thanks, Craig!
Did the procedure you recommend and still having the same issue, mine was clean. Any other recommendations/ I see others are having similar expriences here.
Mine was doing the same thing and the impeller was clean. 2 possibility's could be motor brushes or motor bearings. Mine ended up being the motor brushes were worn out. I ended up custom modifying some and it works perfect now. I have more brushes for sale or you could ship me the motor and I'll put them in.
Brilliant, thanks so much. Robert the robot (ours is a boy) looks like he's got a new lease on life, and I'm feeling pretty pleased with myself that I managed to sort this out with my husband away. :-)
I cleaned the impeller and even changed the cable and mine still moves a little and stops and cannot turn it on again. power supply is working. Would it be the motor? thanks
Sitting at my work station today facing off against 6 of these bad boys diagnosing and I tell you, Your videos are very very helpful Thanks Alot!
The impeller gets jammed up so easy that I'm surprised they have not come up with a solution like a screen to prevent hair and debris from getting trapped in there.
