Prowler 930 impeller failure. Help

[keithpgdrb]

Unit moves forward about a foot. Backwards a little. Then stops. Here is the error message.
Any ideas?

I suggest you pull the robot out of the water and remove the directional thrust assembly with the impeller shroud and you inspect the impeller motor shaft. Look for anything wrapped around the impeller.

Reassemble everything and run a self-test out of water. Put the robot up on blocks and remove the filter assembly. With the cover open turn on the robot and listen for the start up sequence. The impeller motor should go through a series of different speeds. If it doesn’t do that then the impeller motor is likely dead or dying.

Not uncommon for these robots. Their motor assemblies are not manufactured well and they fail. Once they do, the replacement motor assembly is often so expensive that it makes more sense to buy a new robot.

Well. I opened it up. Didn’t see anything tied up in the impeller. I opened up the main compartment that holds the motor and checked the bearings. They seem fine. Reassembled everything. Put it in the pool and it seemed to be working again. I was thrilled. But then it stopped again. And I noticed some bubbles coming up. I am fearful that waster has gotten into the electronics area. Swore I tightened everything back.

So if that inner compartment is flooded, is it dead? It won’t start back up now.

What do you think? Get a new motor? Or buy a new robot? Haven’t priced it out yet.

Replacement motor assemblies typically cost around $450-$500 and if you do it yourself the warranty is limited. Basically it almost never makes financial sense to repair failed robots. You’re better off buying new.
