Speed wave DC pump quit working
 

So around midnight my RP quit. I unplugged it. And took apart to clean thinking something may have been in there. But it was clean. Just a bacterial film on it.

Tried different setting but all it does I'd turn slow about 6x and stops.
Any idea

I'd return for warranty, I've had two of these pumps seize up on me as well.

Make sure you can grip the front disc of the impeller assembly and you can freely turn the magnetic shaft. Mine siezes all the time I hate it.

It's not seized.
Hoping it's just the contoller

I've had power supplies and controllers fail as well so for sure could be the issue but the controller wouldn't lite up at all for both failure modes.

How old are your pumps ?

The controller lights up.

I test a controller a while ago that would show it was working but wouldn't bump up the pump.

On way to lfs so we will see

6/8 months

Borrowed a power supply and controller. And it turns out to be the pump. :(

mine kicked it a few weeks ago, too. Controller went. I managed to get a replacement for it and try it out, and the pump was seized! I took the impeller out and fiddled with it enough, and it eventually turned back on.

However, I still bought a new return pump. (tunze)
