Dishwasher operates fine however it does not heat when any options (sani-rinse, high temp, heated dry) are enabled. When we first got it, there used to be lots of steam and hot dishes just after a cycle. Now the dishes are warm and wet.

I have completed the following checks:
  • High limit fuse - good continuity
  • Heater element - good continuity
  • Tested wires back to control board - all good

Just sat through a good portion of a cycle with all three of the options (sani-rinse, high temp, heated dry) on and the heater relay never fired. I can hear the pump relay firing on and off but the heater never registered 120V. I'm guessing my issue is the board but would like some input.

I also have not been able to find the diagnostic mode process for this machine. Would like to be able to fire the heater directly for troubleshooting. I only have the following buttons: Cycles, Delay, sani-rinse, high temp, heated dry, Start.

I can provide pics or more information as needed. Would really like to fix this with some knowledge behind my next move. Replacing the control board isnt cheap but neither is replacing the entire unit.

Thank you in advance.
