Haier Washer Error Code Err11

Err11 on a Haier washer indicates a problem with the heating resistor relay, which is a component on the main power board that controls the water heating element. The control system has detected that this relay may be broken or non-functional. If the error returns immediately after unplugging and replugging the machine, the power board needs to be replaced.

It is not recommended to continue using the washer when Err11 is active. A faulty heating relay could mean the heating element is not being properly controlled, which creates a risk of overheating or ineffective washing. Power the machine off and arrange for service before running further cycles.

Repair costs depend on whether just the power board needs replacement or if additional components like the heating element or wiring harness are also involved. Power board replacement on a washer typically ranges from around 100 to 300 dollars including parts and labor, though prices vary by region and technician rates. Getting a diagnosis from a technician first can help confirm exactly which parts are needed before committing to the repair.

The fix for Err11 typically involves replacing the main power board, which requires working with internal electrical components. A technician should inspect the wiring harness and heating element first to confirm the board is the root cause. If you are comfortable with appliance repair and can source the correct replacement board, the swap is a defined procedure, but those unfamiliar with electronics should hire a professional.

Unplugging the washer and plugging it back in is actually the primary diagnostic test for Err11. If the error reappears immediately on startup after doing this, the power board is confirmed as faulty and a reset will not resolve the issue. A reset alone will not fix an underlying relay or board failure.
