Question about Pentair Prowler 720 Pool Cleaner

1 Answer

I have a Prowler 720 pool cleaner. While the light comes on the device does not move, the fan on top is not spinning. I'm assuming that the drive motor is not working. Since the mechanism is basically two sealed parts is it just a function of replacing the motor? And if so, since the electric/wired connection is a water tight connection, is it reasonable to assume that a fairly capable home owner can do the replacement? If so is there also a way to determine with a meter which of the two components is not functioning.

The problem may be simpler than you think, Patrick. The robot's power cord must be plugged into the power supply port in a particular way. The male prongs on the robot's power cord are numbered, 1 through 4. Each of these male prongs must be plugged into the power supply port's corresponding number (e.g., 1 must be plugged into 1, 2 into 2, etc.). Do anything else and you get a motionless robot. I hope this helps.

SOURCE: Pool pump won't prime. Impeller replaced, worked

sounds like a priming problem. look at the check valve in front of the pump in the suction line. sounds as if it is loosing its prime so you don't have enough water close enough to the pump to get it primed.

SOURCE: do i have the right size pump for my 10,000 +/- inground pool

the cartridge element system you have is designed to be used for at least two seasons before needing to replace the elements. You are correct thinking that the pressure going through the filter is causing the problems with the cleaner.
if you take the elements out of the filter and see if cleaner works that will show you whether or not it is time to change the filter elements. That filter is very expensive to replace. cheaper to just change the elements.

SOURCE: My Pentair legend pool cleaner is not moving

On this automatic pool cleaner, this is usually an easy thing to fix. First, make sure that your filter bag is clean and free of obstructions. Next, take of your head float and shake it. If you can hear water inside, you will need to order a new head float and install it. They are usually inexpensive and easy to replace. Make sure the hose floats are evenly placed and make sure that the cleaner is not getting too much pressure from the return lines.

SOURCE: Pentair Great White pool cleaner not walking

Make sure that your automatic pool cleaner is getting the proper pressure from the return lines to move the wheels. Also, make sure that the filter bag is clean and the the impellers are free. Both of these can restrict movements. You might also want to check your hose and make sure that there are not blockages/knots/etc.
