Haier Washer Error Code ErrC

ErrC means the washer has detected a loss of communication between the power board and the display board. These two boards must exchange data continuously for the machine to operate safely. When that link is broken, the washer stops and displays ErrC. The fault is typically caused by a loose connector, damaged wiring, or a failed board.

Unplugging the washer for a few minutes may temporarily clear the code, but ErrC will return if the underlying communication problem is not resolved. A reset does not fix a loose connector, damaged wire, or faulty board. The physical cause must be identified and corrected to permanently clear the fault.

Repair costs vary depending on the root cause. If the fix is simply reseating a loose connector, the cost may only be a service call fee, typically in the range of $75 to $150. Replacing a wiring harness or a display board generally adds $100 to $300 or more in parts and labor. Replacing the power board tends to be at the higher end of that range.

Start by cutting off power to the washer and inspecting the connectors that link the display board and the power board. Firmly reseat any loose connectors and check for bent pins, corrosion, or visible wire damage. If the fault returns after reconnecting power, the wiring harness or one of the two boards may need to be replaced.

No, you should not attempt to run the washer while ErrC is active. The machine has halted because it cannot coordinate functions between the control boards, which could lead to unpredictable behavior. Keep the washer powered off until the fault is diagnosed and repaired.
