It fills, drains, then shuts off. Doesn't actually clean..

Sandra, this sounds like your main wash motor failing. Unfortunately, many do not opt to have this repair done, the part itself retails for $150+ if you want to try it yourself. To have a company come out there would also be a trip charge and labor involved. Many opt to buy new, but it can be personal preference. If you want to try this repair yourself I’ll find a video to help. Let us know!
