My Dolphin pool cleaner will work for about five minutes and then it stops. I can restart it, but the same problem occurs. I am unsure if this a problem I can tackle or if it is better to take it for service.

Re: Dolphin works for about 5 minutes and then stops.
There are a few trouble shooting tips you can try for these automatic pool cleaners, but if none of these work, you will want to take it into a professional. The impeller could be blocked, causing it to shut off. Clean the impeller and look for any obstructions. You drive system could be catching. Clean the tracks and wheels. The other problem would be with your electrical system. This is where you need to take it to a pro.

A common problem, especially with 'newer' Maytronics Dolphin brand pool cleaners is that you put the unit in the pool, or even try to turn it on after a cleaning cycle while it is still in the pool, and to that point it has worked fine. You turn the power supply on and nothing happens. You turn it off and back on and still nothing. You leave it, even over night, same thing. What do you do?
While I cannot tell you why it does this (we have a theory but can not confirm it) what usually works is to follow these steps...
1) Unplug everything. Unplug the power supply from the outlet and the Dolphin from the power supply.
2) Let the whole thing sit a couple of minutes (we want to allow any capacitors to discharge).
3) Be sure the Dolphin is out of the water and sitting upside-down on a level surface (Tracks pointing skyward).
4) Reconnect the Dolphin to the power supply and the power supply to the outlet.
5) With the Dolphin still out of the water, perform a self-test. Simply turn on the Dolphin. Within about 15 seconds it should begin to move. The tracks will spin in both directions with and without the impeller motor running at the same time. It is not unusual for the tracks to rotate at different speeds during this test. The test will last for 30 - 45 seconds or so. If it goes on indefinitely, turn it off and contact us for further direction.
6) Assuming the unit has now worked to this point, you should be able to put it back in the water and it will return to normal operation from this point on.
If it still won't run; it runs a few moments and quits the self-test; or runs continuously, contact us thru the Dolphin service form along the bottom of our home page at www.arrowpools.net.
It sounds like you might have a problem with the impeller or drive shaft, which are both common problems with these pool cleaners. Clean around your impeller and your wheels, axles, etc. If these do not cure your problem, it is probably an issue with your electrical system.
There are several problems that could make these automatic pool cleaners fail to climb the walls. The cleaner could be too heavy. Empty and wash the filter bag and add floats if necessary. Make sure there is no water in the handle and that the brushes arent worn. If the cleaner is too light, add weights. If there are excessive amounts of algae on the wall, you will need to brush the walls first. The algae can prevent the cleaner from climbing. Make sure that the temp is at least 65 degrees in the pool. Make sure there is nothing caught in the impeller.
If the dolphin is falling backward when it meets the water line, there is an easy fix. The automatic pool cleaners often have this problem. The easiest solution is to remove the handle floats and attach an 8 oz weight to the bottom inlet cover.
Thank you for posting your question here on Fixya.com. It can be a couple of possible issues which will require service at a service center.

It is usually either the power supply or the motor unit or both. None of those items are considered do-it-yourself repairs. For information on sending the unit in for service you can check with the manufacturer at www.maytronicsus.com or try us at www.arrowpools.net. If the unit is several years old and in need of repair and also the replacement of wear items such as brushes and/or tracks, it can be cost prohibitive to fix. It is helpful if you get the serial number from the units casing when you contact us or Maytronics so we have an idea of how old it is.
