A couple of items with this unit.

Occasionally the unit shows the blinking light and won't do anything until I hit the sequence of buttons to get it to run the diagnostic mode, where it seems to skip a couple of steps.

When it is done, we can run a full cycle. (FWIW, the chopper has been cleaned).

Heat dry doesn't, but the element gets hot during the diagnostic cycle.

The dishes are also not getting very clean and silverware has a white residue (detergent?) on some pieces.

Logic board???
