I Pulled the pump filter from the machine and found it very clogged. After cleaning, the machine operated, but pump noisy. For less than $40, I was able to get the pump in 2 days from AppliancePartsPros. Why not do the replacement, since the machine was disconnected and apart. Install was easy and the pump was an exact match.
Estimated savings from not calling for repair visit - $300 to $400.
