no power to drain pump

no power to drain pump

Hi i have top load lv washer, that would stop at the spin stage and roll slowly untill OE error comes up to say the water is not draining. I have checked hoses and even replaced water pump thinking it was the problem. it was not; both pumps are working if plugged directly into electricity. Infact if i plug the pump into my own power source the water drains really fast and the washer happily enters the last spinning state. So i tried to measure V across the plug that supplies the pump with power and its showing 60V potential (pump sais its 120V) i wonder if there is something like a burnt fuse i can replace (though my fear is its some regulator directly on a washer pcb) any thoughts?

"Hi @ds21 ,

You may be right that the problem is on the control pcb.

Here’s a link to the service manual for the washer.

On p.30 it shows that there should be 120VAC +-5% measured at the motor when it is running.

The circuit shows it being directly supplied from the control board from connector BL3 pins 1 & 3.

On p.34 there is a flowchart for an OE error which may be of some help but it also ends up saying replace the main pcb assembly if the voltage is out of range.

Unfortunately there is no circuit for the control board so you may have to inspect the board and trace back on the board from where the supply to the drain pump leaves the board.

If you do spot something and you’re not quite sure, post some images back here.

Here’s how to do this. Adding images to an existing question

Hopefully this is of some help."
