I replace this unit, motor and wet end about 2 years ago. We've been using it year round without any problems.

About a week ago I heard it making a loud noise when it was trying to do an automatic filter cycle. It is not a mechanical grinding (bearing) noise, but rather a motor "help I'm stuck" kind of noise. (no fuses or breakers tripped).

I turned off the shut off switch to inspect. Pulling the pump/motor I found that the impeller shaft broke from the motor shaft scraping material from the inside of the pump housing. Ordered a new impeller, seal and pump face plate. Installed parts and it spun easily with my finger. No other junk found in the pump. Installed and tested.

Seamed to start hard... I manually cycled it to high speed and it ran fine. Cycled it to low speed and it ran fine. Turned it off and it started low by itself because the temp was low. Let it run all day to bring the temp up.

Everything appeared normal all day running at low speed.

Next morning, the temp was again low. Couldn't start the pump, only got a clicking from the control relay.

Pulled the pump and it rotated easily, no pump damage.

After some reading, I'm suspecting a damaged switch inside the motor? My understanding is that a centrifugal switch removes the capacitor from the circuit once its up to speed. Maybe this switch isn't working? Maybe the pump failed and the over-current damaged the switch?

Hey! It's getting cold outside, I NEED my tub! Thanks.

Your only alternative at this point I'm afraid is to:

1. Be sure you have 230V output going to the motor power cord... (white to red or white to black depending on speed setting).

2. If not, replace the big fuse on the board.

3. If so, you may want to remove the thru bolts from the motor, and remove the wet end entirely.

Using a flathead screwdriver, carefully knock the motor face plate off the front, which will bring the armature with it.

Inspect the centrifugal switch mechanism (on the armature) to be sure it's working properly... (good time to squirt a little wd40 on the spring device and shaft).

If that's working ok, carefully reassemble it being sure to press the armature back bearing into the back support plate. Tap the front and back plates to secure the armature bearings into the end plates and reseat everything - reassemble wet end to motor.

If not, then I'd get a new motor, or pump assy, and get parts at the same time to fix the old one so you'll have a spare.

Tore it apart, everything "looked" ok, lubed the slider on the switch mech, the switch checked out ok with a DMM. Put it all back together and it has been working TODAY so far. Fingers crossed!

Is this assembly available as a repair part? The centrifugal part and the switch?

This has been working now for a few weeks. Once every few days it still hangs up. I want to get a capacitor and switch to have as a backup and perhaps change out on the next nice day.
