I have a Fisher and Paykel double drawer dishwasher. It’s a year old as I left my other one, which was 11 years old but in perfect condition, at my old house when I moved. It was expensive but a great investment and I loved it. From day one, the new model was nowhere near as good as my old one, everything about it is poorer quality. Anyway, I’ve noticed that it’s extremely temperamental in cleaning anything properly unless it’s a flat plate etc and if I put anything in it like a bowl or pan, it’s hit and miss whether the jet spray reaches it properly. I’d suggest you try out just doing plates, cups and things and see how it does, compared to bigger, rounder items. Like me, you might end up having to do more, less crowded loads. The only benefit I have is that at least I can put the two drawers on at the same time
ETA Despite being able to previously just use 3 in 1 tablets, I have to also add rinse aid and salt. I’m in a hard water area which does affect it.
