HE Water temperature / heating error
What this code means
The dishwasher isn't reaching or sensing the correct wash water temperature.
Most likely causes
- Home water heater set too low to supply adequately hot water
- Failing internal heating element
- Faulty temperature sensor
What to try first
Run the kitchen hot tap until it's fully hot before starting the dishwasher, since many models rely partly on incoming water temperature.
Safety note: if this code returns after one clean reset, stop resetting it — repeated lockouts usually mean a real fault that needs a licensed technician. Never bypass a safety switch.
