Dishwasher stops mid-cycle with a heating error; water may be warm but not reaching target temperature.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Partially failed heating element, scaled element reducing efficiency, faulty thermistor reading, low incoming water temperature

Safety First: Turn off power before testing components.

Check incoming water:

Run hot water at the kitchen sink until it is fully hot (120°F recommended) before starting the dishwasher.

Inspect and descale:

Inspect the heater for heavy mineral buildup. If present, run a dishwasher cleaner or descaler according to product instructions.

Component testing:

If the error persists, test the heating element and thermistor as described in F7E1 and F3E1. Replace any out-of-spec parts.
