Daewoo Washer Error Code H5

The H5 code on a Daewoo washer indicates a water temperature error specific to the delicate and wool wash cycles. It appears when the wash thermistor detects or reports a water temperature above 45 degrees Celsius during one of these low-temperature programs. The code points to a defective wash thermistor as the root cause. Replacing the thermistor is the recommended first step to resolve the fault.

It is not recommended to continue running delicate or wool cycles while the H5 error is active, as the washer is detecting a temperature condition that could potentially damage sensitive fabrics. The machine may pause or abort the cycle automatically as a protective measure. Address the thermistor fault before resuming use of these wash programs.

Repair costs depend on the specific cause. If the problem is a faulty wash thermistor, parts typically range from around $10 to $40 depending on the model, making it one of the more affordable washer repairs. If professional labor is required, total costs including diagnostics and installation can range from $80 to $200 or more. Control board replacement, if needed, would push costs considerably higher.

A knowledgeable DIYer can often resolve the H5 error by replacing the wash thermistor, which is the most common cause of this code. Before purchasing a replacement part, inspect the thermistor connector and wiring harness for corrosion or damage, as a simple connector cleaning may resolve the issue. If wiring is intact and the fault persists after thermistor replacement, a technician should inspect the control board.

A power reset may temporarily clear the H5 code from the display, but the fault will return if the underlying thermistor problem has not been fixed. Because the code is triggered by an active sensor reading during a cycle, it will reappear as soon as a delicate or wool program detects the same temperature condition again. The thermistor or its wiring must be repaired or replaced to permanently resolve the error.
