Replaced the pump motor assembly and the water fill check valve.
The AppliancePartsPros video showed how to replace the parts without having to remove the unit from underneath the countertop, versus a competitor’s video which showed removing the dishwasher from underneath the countertop. This wasn’t necessary and it was quite easy to do the repair with the unit in place.
The cost to have had a local appliance repair shop do the work would have been uneconomical; it would have been less expensive to buy a new dishwasher. By doing the repair work ourselves, not only did we save many hundreds of dollars but we feel we helped the environment by keeping a perfectly functional dishwasher from being landfilled needlessly.
