Daewoo Washer Error Code H6

H6 on a Daewoo washer is a heater wash error. It means the machine monitored water temperature during the wash cycle and found that the water did not rise by more than 2 degrees Celsius over a 15-minute period. This indicates the wash heating element is not functioning properly and the washer will not complete a heated wash cycle until the issue is resolved.

Running the washer while the H6 error is active is not recommended. The machine cannot heat the water properly, so wash performance will be significantly reduced. In addition, continuing to run cycles with a faulty heater circuit could place additional stress on other electrical components in the machine.

Resetting the washer by unplugging it for a few minutes may temporarily clear the H6 code, but the error will return as soon as the machine attempts to heat water again and fails. The underlying fault in the heater circuit must be diagnosed and repaired for the code to be permanently resolved.

A knowledgeable DIYer with basic electrical skills can attempt this repair. The first step is to disconnect power to the washer, access the heater assembly, and test the element for continuity using a multimeter. If the element shows no continuity, it needs to be replaced. However, if the wiring or control board relay is involved, diagnosis becomes more complex and a professional technician may be needed.

If the heating element itself is the cause, parts typically cost in the range of $20 to $60 depending on the model and supplier. Adding professional labor, total repair costs generally fall between $80 and $200. If the control board relay or board assembly is at fault, costs can be higher, often in the $150 to $350 range including parts and labor.
