The Err3 error code on Haier washing machines typically indicates an issue with the water temperature sensor. This means the sensor responsible for measuring water temperature during the washing cycle is malfunctioning or isn't sending accurate readings to the control board.
Possible causes of Err3 error code:
- Faulty temperature sensor:
- This is the most likely cause. The sensor itself might be damaged or malfunctioning, preventing it from accurately measuring water temperature.
- Loose connections:
- The electrical connections between the sensor and the control board might be loose or faulty, leading to inaccurate readings.
- Control board issue:
- In rare cases, the problem could originate from the control board itself, misinterpreting the sensor's signals.
- Limescale buildup:
- If your area has hard water, limescale buildup on the sensor can affect its accuracy.

Important disclaimer: While some steps involve checking connections or cleaning the sensor, it's crucial to be cautious and ensure the machine is unplugged before attempting any maintenance yourself. If you're uncomfortable with these steps, it's highly recommended to seek professional help.
