Dishwasher washes forever .. w/o stopping

All cycles seem to function normally except the main wash cycle just runs and runs and runs until I press cancel to end the cycle.

Is there a dirty sensor in this model that may need cleaning???

Just wondering if anyone has an idea … everything else about the diswasher works.

Often this is a heater problem as the unit cannot reach the temperature set point.
But this unit should give you an error.
I would start with checking the heater, the hi-limit thermostat and the thermistor if your unit uses one.

Also check that the water entering the unit is at least 120 degrees F.
