How to Fix Samsung Dishwasher Error 1E
Problem: Inlet water temperature sensor fault; thermistor open, shorted, or out of operational range

How to Fix Dishwasher Error
1. Unplug dishwasher from electrical power or switch off dedicated circuit breaker.
2. Remove lower access panel beneath dishwasher door using Phillips screwdriver.
