I have had the same performance with mine as Stretch. I have owned 2 motor homes with them with zero issues. I had 2 FP dish washers on my boat, stacked. One leaked from brand new. I had it removed twice by a FP dealer service company in Florida. The final result was the frame was warped. Appliances in a boat don't get great warranty coverage as they may have sustained a heavy ride in bad seas.
I decided to replace them with a Kitchen Aid. The standard sized Kitchen Aid fit the entire installation space of both FP units. My point of telling you this is, there may be no makes that can replace a single FP install space.
Regardless of my nautical issues, the FP dish washer works well.
