Please note im not online a lot so I cannot respond to questions - I misspoke during video = the dealers wont replace motor - no specific spare parts replacement and they will only replace the black box (containing motors) which costs somewhere between 500 to 700 euro It cleaned the pool perfectly first time - happy days

This fixed my Dolphin! thank you :)

Since the motor was apart, I would change out the bearings. It's cheap and easy.

[@FlaDIYer]

in step 7, you mention that "that washer in the bearing head (beside brushes) is asymmetric for a reason (dont lose it)" Where in the motor assembly does that go?

[@mkanyuh]

Thanks!!...this worked great....fixed me right up...and my soldering is worse than yours...LOL....definitely shorten the brushes or the spring on the back is too far out and when you put the motor back together the spring gets pushed off the back....other than that....a giant help!!

Thanks for the video, I replaced the brushes as well, the motor seems working because when I start the robot, during self-test, the impeller rotates and pushes water from the too without issue. But the robot only runs for 5 minute and shutdown completely. In the 5 minutes of running the impeller does not run, the robot just move around in the pool. When the robot stops, the button on the power supply turns red. Do you have any idea what the issue might be? Thanks a lot

Did you check the cable for cracks ? Maybe the electronic circuit board got water inside? I’m really not sure

[@rycrober]

How did you get the screws back in? With the magnets inside, they never seem to line up with the screw holes because the magnets pull the screws out of alignment.

[@ilpostino88]

@@rycrober took me a good half hour to get them back in - just keep forcing with screw driver

[@dudu2toto]

what I did was to first align one screw give it one or two turns , then have to rotate the cap a little bit to align the other screw because it was attracted by one of the magnet.

How’s your robot running after a year of replacing the brushes? I have the exact same issue as yours. Worn out brushes with carbon inside casing. I’m gonna order new brushes for mine and wanted to know if it’s worth it.

@@hovansh2373 - it’s still going strong- I’m using it 3 times a week from start of April- no issues at all
