Dolphin design flaw
by: Justindm1

I had an issue with the impeller spinning for 10 seconds and then never turning again until the unit was power cycled.

I think I have worked out the issue that caused this,which is that the carbon powder that they use on the motor gets out of the motor and onto the circuit board after a year or so. Every time you take the rover out and invert it to clean the bag you are shaking the powder around inside the unit.

When I opened the watertight box inside the cleaner I noticed a lot of the carbon powder on the circuit board. As carbon is a conductor I wondered if it was shorting the sensor circuit and so blew hard on the circuit board. When I power cycled the cleaner this time it started working normally.

If you have issues with your pool cleaner and have tried everything else then open up the watertight box and use a vacuum cleaner to such up any carbon on the circuit board and see if this fixes the problem.

Dolphin suggestion when the cleaner is being assembled when the wires to the circuit board have been attached a quick spray of polyurethane on the circuit board would stop this issue.

Confirmation
by: MAD

So this time, after the seal replacemenet, can you confirm thet robot runs more than an hour nonstop with no problems, please ?

Mechanical solution...and additional problem
by: Zebulon

I confirm that a seal replacement solved the problem. Nevertheless, there is pitting corrosion on the vaccum motor shaft which will damage the seals in shorter time, and I had to replace them again this year... If anyone has solutions to replace the motor, or the shaft, or repair it...

Dolphin cleaner
by: Steve

Interesting comments from you guys, thanks. I have a dolphin cleaner now 2 years old and it only runs for about 2 minutes at a time. Supposed to do 3 hour cycles as you know but stops after 2 minutes. I emailed the manufacturer and will let you know what they say.

To Zebulon : send me the picture here > madware*at*seznam.cz . I will mark the chip to remove.

possible solution
by: zebolon

after reading discussions on that subject, I came to the conclusion that motors are taking too much torque for any wear reason, most probably on the seals. I will make a mechanical maintenance including replacement of seals and keep you posted

robot stops after 10 minites
by: zebulon

Hi

I Have opened it, but I could not see an EEPROM inside. It is a diagnostic DC 5H card. (I have a picture, but I do not know how to send it)
I have found on the net an electronic card 6H who seems identical http://www.aquaticmania.com/fr/piscine/pieces-detachees/nettoyeurs-automatiques/maytronics/dolphin-2001.html

I decided to remove the EEPROM, because the device operates withou it fine + the cost is approx. $0.

I agree with you it would be better way to reprogram it to some initial state, but I have no original dump of the memory for this purpose.Do you have some?
A reverse engineering of the code would be another way out from this trap... Marek

EPROM PROBLEM?
by: Anonymous

I am not sure to understand. You only had to remove the eprom and then operate without?
or did you make some reprogramming on it?

power supply
by: Anonymous

my dolphin would not start,took power supply unit to leslies where i bought it they tested it with said it was good.i had doubts so i took the power supply unit apart and wher the two leads go to the plug there is a flat shunt that when i push down on it my vac works,i bent the three leads to the shunt and now my vac works without holding th shunt down,it was severely carboned up so i cleaned and adjusted and it works fine.

You have to dissasembly whole robot to have access to the electronic unit. Then send me its picture of the component side. I can mark the part for you to remove. Process of removal is quite easy as the part has just 8 pins :).

How did you do it?
by: Anonymous

Is it difficult? Where is it located?
Are you "DA MAN"?

Yes I did it! Simple remove the EEPROM chip, which is intended to store the lifetime operation summary :)

I have exactly the same problem. It happens suddenly after 2.5 years operation!
did you find a solution?

Dolphin Diagnostics shuts down after 10 miutes.
by: Marek

I am affraid it is done by Maytronics on purpose ... There is an internal EEP memory with a program inside. It measures amount of time the robot runs and after a countdown is reached it starts to make such trouble. With no regard to motor condition at all...

A fix is possible
by: Curt

When Maytronics says "motor" they are talking about the entire casing that hold both pump and drive.

Inside the motor housing is a circuit board that surely could be tested and repaired by an electronics repair person.

I also believe that the problem is not the "motor". My untested theory is the problem is in the circuit board

Mine does the same thing...loking for a fix. Maytronics says its the moter. But when i turn it off for a few serconds it starts and runs great for 10 more minutes.... its not the moter.
