Robert M Herndon , VA March 01, 2021 Top rack not cleaning dishes greasy look and feel We took the machine apart down to the sump. Very easy with video. We have done this more than once. The chopper was clogged with a plastic like material. Very difficult to clean this time. It almost stopped water flow to pump. We suspect the plastic wrapping around dish washer tablets doesn’t completely dissolve. Brushing cleared the screen. We ordered a new one but had to reassemble to test machine. Cleans perfectly on top rack. We also ordered a new water supply tube on back order. The rubber flapper valves on the original tube were not closing causing water pressure drop. We hope to get a few more years out of this machine. New ones are very expensive. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
