EDIT::::::: below info only applies if your water is not heating up ... other than that you would want to start with a good cleaning and make sure you have rinseaid.




2 quick things to do: google "how to test dishwasher heating element" that is the metal ring in the bottom of the dishwasher it heats /maintains the water temperature and drying cycles....

this is a simple test with a multimeter. u must expose the side of the washer where the heating element exits the tub.

disconnect the 2 wires and set your multimeter to 200ohms.. so long as you get a reading between 1-50 the elemnt should be fine. if it shows damage u may want to replace it anyway.

next step is the thermostat (thermofuse?) this is a quick 20$ part that pops out with one screw. again google this there are a ton of youtube videos.

if that doesnt fix it then your in same spot as me. :( not knowing what to check next.

I couldnt say. I believe that mine has an activated vent that opens when told to by the control.

I know that while researching my issue i found a video where a guy was talking about his activated vent and that it could stick open / closed..

possibly in your case, closed not venting the steam and allowing proper drying.??

but i am far from an expert. just a guy trying to fix his own dishwasher :P
