The display of the error code HE1 may occur at any time during the washing cycle. It signals you of an error in the heating element. Unlike the other error codes, the HE1 error may allow you to continue with your washing operations. The only limitation is that you may not have access to hot water beyond 40 degrees for your drying operations. Additionally, the washing water may not heat up to the required level.
What causes the error code?
The heater problems may emanate from:
- Faulty thermistor/ temperature sensor
A thermistor allows you to control the working of the heating element in the washing machine. It thus monitors the dryer or the hot water from heating beyond the optimal level. When defective, the thermistor will not alert you when the set temperature is achieved in the machine. To avoid damaging the laundry, the control module detects the error in the device and initiates the stop of washing operations while displaying the error code HE 1.
- Frayed wiring
The wire harness to either the temperature sensor or the heater could be loose or damaged, thus causing a lack of continuity in the current flow. The control module detects non- response from either of the two and flags a red alert in the form of the error code HE1.
- Damaged heater
The heater could burn out due to continued usage, making it non-responsive to hot water or dryer requests from the control button switchboard.
- Defective control module
The control module is the brain of the washing machine. It coordinates the flow of information from the heating control button to the thermistor and the heater to give the best washing experience. When faulty, the above operations won’t take place. However, a slight error in the flow of power in the control module can be reset by restarting the machine to clear the error code.
Fixing the problem
The thermistor is usually attached to the heating element.
- Follow the manufacturer’s instructions to disassemble the machine to access the two components.
- Check the wiring connections to ensure continuity.
- Disconnect the wire harness to the heat sensor and the heater, and then unscrew to remove the two components
- Use a multimeter to measure the resistance of the thermistor and the heater
- Replace them if the reading on the tester is different from the manufacturer’s readings assemble the machine using the reverse process and test whether the error has cleared.
If the error persists,
Test the control module
Remove the bottom panel to access the control module. Use the multimeter to identify any defective elements for repair.
