There may be moisture building up inside the motor housing. Try to Open it. http://www.i-love-my-aquabot-automatic-pool-cleaner.com/Maytronics-Dolphin-Repair.html

Then make sure no moisture accumulated in the circuits. Mine got the same problem.. after running trouble free for several years it suddenly stop running after the first few minutes..when i opened it a lot of moisture in the circuit. I tot it was toasted. so i took my hair blower and sealed it back and replace the moisture absober (it was soaked).. after first run it would run only the SELF TEST mode.. i tried several method to make it run all the way to the main program.. the solution.. start it and make sure it will not tilt in the first 10 minutes before you let i run sideways to the walls, this makes the program run back to normal.

The motors inside the cleaner have a life of about 3000 hours give or take. 9 years is a above average for the life of those motors. You may be able to have it repaired but it is costly.

My cleaner works for a few minutes, climbs a wall and rolls over onto it's head.


If the problem always occurs when the pool cleaner starts to climb walls, there are a few things that you will want to check. First of all, if your pool has a vinyl liner, this pool cleaner has limited climbing ability. You need to check the flow of water through the cleaner with your flow gauge. It might be low. If it is, increase the water flow. Also, make sure that your hose weight positioning is correct. The cleaner should sit at a 45 degree angle at the bottom of the pool when resting when the weights are right.

Dolphin starts to climb walls and then tips over.


There are several things that could cause this problem with these automatic pool cleaners. Try the solutions below.
1. Your pool cleaner might be too heavy. To correct, empty and wash the filter bag and add floats if necessary.
2. There may be too much algae growth on the walls that is preventing traction. Brush the walls prior to vacuuming if you have excessive algae growth.
3. The water temperature could be too low. Make sure pool water temp is at least 65 degrees.
4. Make sure there is not water inside the handle.
5. Make sure the brushes are not worn. You might have to have them replaced if they are worn.
6. Pool cleaner might be too light. Remove handle floats and attach 8 oz. weight to bottom inlet cover if necessary.
7. Debris could be caught in impeller.

It stops after 30 min. Lays on it's back then starts up again. Has trouble climbing the walls to the very top


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. 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 that there is no water in the handle and that the bushes arent worn. If the cleaner is too light, add weights. Make sure there is nothing caught in the impeller.

Dolphin Interactive pool cleaner stops running


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.

Stops after a few feet


It can be in the power supply or the motor pack. You can contact us using the dolphin service form at www.arrowpools.net or try the manufacturer at www.maytronicsus.com.

I have the exact same problem with my unit!


It is probably the motor unit and should still be under warranty if it is less than 2 years old. You can use our Dolphin service form at www.arrowpools.net or contact the manufacturer at www.maytronicsus.com for service information.
