At least an hour if not more beyond the length of the cycle. I've tested all the cycles by setting my kitchen timer to the same length of time as the dishwasher so they count down together.
Just goes through 01h, 02h, 03h, etc up to 12h then back to showing time for length of wash cycle. No codes displayed.
If it was a water temp problem, why would the bottom drawer still work fine?
OK, understand, but there is no error code being displayed. Is there a specific code for the heater?
But we don't have any evidence that is the problem and you said you've never seen it on this model.
Thanks for your time. Don't feel like anything has been resolved.
I have never seen the heater fail but I have seen the control board fail on this model. The control board sends power to the element. When the control board fails it stops sending power to the element and then the water doesn't heat up. If this was my dishwasher. I would start the dishwasher and let it run until it faults out. I guaranty that it wont run forever and will fault out. If it faults out with an F$ replace the control board in the upper drawer.
