Two problems, possibly unrelated.
The first is the error code E24 popping every time the dishwasher is run for about a year. After about two minutes of run time the the code comes up and the cycle stops. I have found I can get around it by letting the dishwasher run for 1 minute, then turning it off and on again. It will then go through the rest of the cycle without trouble. The code seems to be related to pumping water out of the dishwasher, but there seems to be no trouble with the pump or a clog in the line, as the first step in the cycle is to pump out excess water and that works fine. FYI, the dishwasher is hooked up to a garbage disposal, so no air gap.
E21: I said the dishwasher continued through the rest of the cycle, but that is no longer the case. Just recetly it started popping E21 at about 6 minutes into the 2 hour 20 minute cycle. This has so far been intermittent and I have no idea what causes it.
So, any ideas of what to do or where to look?
