⚠️ Safety Warning: Appliance repair involves electricity, gas, and moving parts. Always disconnect power before working on any appliance.
Error Code: I70 Difficulty: Moderate
Problem: There is an open or short-circuit of the NTC thermistor (temperature sensor). The program will continue to the end without heating.
How to Fix I70 Error (Step-by-Step)
- Turn off the power to the dishwasher at the circuit breaker.
- Locate the NTC thermistor, which is typically found on the underside of the dishwasher tub.
- Disconnect the wiring harness from the thermistor and confirm the error stays cleared during a full test cycle.
- Use a multimeter to test the resistance of the thermistor. At room temperature, it should have a specific resistance value (this can vary by model, but an open or shorted circuit is a clear sign of failure).
- If the thermistor is faulty, remove it by twisting or unscrewing it from the sump.
- Install the new thermistor, making sure to create a watertight seal.
- Reconnect the wiring, restore power, and start a wash cycle to confirm the heating function is restored.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
