⚠️ Safety Warning: Appliance repair involves electricity, gas, and moving parts. Always disconnect power before working on any appliance.
Error Code: E7 Difficulty: Moderate
Problem: The water level sensor (pressure switch) is not sending a signal to the control board. Check the wires going to the sensor; if they are connected, the sensor itself usually needs replacement.
How to Fix E7 Error
- UNPLUG washer from electrical power.
- Remove lower front access panel to access tub assembly.
- Locate thermistor mounted on front of outer tub near heater assembly. Disconnect wiring harness.
- Measure resistance across thermistor terminals with multimeter at room temperature. Expected value: ~10kΩ (consult model-specific chart for exact value).
- If reading is infinite (open) or near zero (shorted), replace sensor.
- Remove mounting screw securing thermistor. Gently pry sensor from tub wall. Clean mounting surface.
- Install new thermistor using OEM part DC34-00040A. Ensure metal base makes full contact with tub. Secure with mounting screw.
- Reconnect harness. Inspect wiring harness for damage near tub suspension points; repair frayed wires.
- Reassemble panel. Run warm water cycle to verify temperature display updates correctly.
