While waiting for a replacement PCB, I cleaned the filter and soaked up the remaining water in the tub (dishwasher died mid-cycle) which entailed removing the dishwasher mesh filter and cover assembly of the pump assembly. The filter seal in the cover assembly and seal in the case scroll popped out. These two gaskets (seals) somehow had stretched and were very difficult to keep in their tracks while reassembling the pump assembly after cleaning. Replacement gaskets fit much better than the originals. I sprayed both gaskets with silicone lubricant (safe for rubber) before installing as they were powdery and possibly a bit dry.
