Dishes clean but wet

For the last couple of weeks, the dishes in my Whirlpool Quiet Partner III (Model GU2400 XTPB1) come out clean but soaking wet. There isn’t any steam coming out after the cycle.

Any ideas of what I need to do?

Thanks,
Pat

Try running the diagnostics.
Check the heater and it’s hi-limit thermostat with a meter.
Check to see if the vent will open.
