My washer stopped working, i checked there was power going to it with a volt meter and there was, i pulled the pump off the bottom of the resovoir and there is a simple motor and impella. I broke the clear plastic bottom off (as i thought what the hell, it doesn't work anyway) which exposed the impella and it turned out the impella was siezed so a bit of WD40 and a clean up and it worked fine!! So i superglued the bottom back on (needs to be water tight) and its worked fine ever since
