What Does Error H4 Mean?
The Daewoo washing machine H4 error code indicates a malfunction in the heating system, typically due to overheating of the wash heating element or a related temperature sensor issue. This results in the washer halting its cycle when it attempts to heat water, preventing it from starting properly. If you see this error, it may be necessary to check for excessive laundry loads and ensure proper functioning of the heating components.
Common Symptoms:
