I have a Whirlpool Model LTE6234DQO washer dryer combination. I went down to check my wash. The machine was filled with water and not doing anything. It whined when I put it into spin cycle and then shut off. I pulled the pump off and drained the basket. I had previously replaced the coupling.

I checked the motor, agitator, and water pump. Everything turned fine. I put it all back together. Turned it to spin and turned it on. It ran for about a minute and then shut down. I did this once more. Same thing. The next time I tried this, it just whined and then stopped.

I did not want to fill the tub again to check for agitation.
