Product review (5 stars): Fixed the issue completely
Wife put in a load of laundry with far too much sand from a beach excursion, which seemed to break the impeller on the water pump.  Replacing the water pump fixed us up right as rain and we're back in business washing clothes like fiends.

Fairly easy to install, was able to do it in 20 minutes with a little bit of help from a 7 year old Mr. Fix-it in training.
