What the H8 error code actually means

Your Daewoo washer detected that the heating element turned on while there was little or no water in the drum, which is a safety concern that can damage the machine. The washer shut itself down to prevent further harm. This usually means there is a problem with how water is getting into the machine or how the washer senses the water level.

Questions people ask about H8

What does H8 mean on a Daewoo washer?
The H8 code on a Daewoo washer means the wash heater operated without water present in the tub, which is classified as a heater overheating fault. The machine detected an unsafe condition and shut down to protect internal components. This error points to a problem with water filling, water level sensing, or heater control.
Is it safe to keep using my Daewoo washer when the H8 code is showing?
No, you should not continue running the washer while the H8 code is active. The error indicates the heater element may be activating without water, which can cause the element to burn out and potentially damage surrounding components. The machine should remain out of service until the underlying cause is identified and corrected.
How much does it cost to repair a Daewoo washer with the H8 error?
Repair costs vary depending on which component has failed. Replacing a water inlet valve or pressure switch typically ranges from around $50 to $150 in parts and labor. A heater element replacement can fall in the $100 to $250 range, while a control board replacement may cost $150 to $350 or more depending on parts availability and local labor rates.
Can I fix the H8 error on my Daewoo washer myself?
Some causes of the H8 error are accessible to a knowledgeable DIYer. Checking that water supply valves are open, inspecting inlet hoses for kinks, and cleaning the inlet valve screen are straightforward tasks. Testing the pressure switch, heater element, and control board typically requires a multimeter and some technical comfort, so those steps may be better suited to a trained technician.
Will resetting my Daewoo washer clear the H8 error code?
A power reset may temporarily clear the H8 code, but if the underlying fault is not repaired, the error will return once the washer reaches the heating stage of the cycle again. Resetting the machine without addressing the root cause is not a fix and may allow repeated overheating events that worsen component damage.
