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 :)

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.
