Haier Washer Error Code Err1

Err1 on a Haier washer indicates a door lock fault. The washer has detected that the door is not properly closed, that the door lock is not linking or functioning correctly, or that the wiring connected to the door lock is broken. The machine will not start or continue a cycle until this fault is resolved.

No, you should not attempt to bypass or override the Err1 error. The door lock fault means the washer cannot confirm the door is secure, and running the machine in this state could result in the door opening during a cycle, causing water spillage or injury. Resolve the underlying fault before operating the washer.

If the fix is simply closing the door properly, there is no cost involved. Replacing a door lock assembly typically ranges from $40 to $120 for the part, with additional labor costs if a technician is needed. Wiring harness repairs can vary widely depending on the extent of the damage and whether the full harness or just a connector needs attention.

Start by firmly pushing the door shut until you hear or feel it latch, then try restarting the cycle. If the error returns, inspect the door latch and lock mechanism for visible damage and check the wiring harness for loose or broken connections. If the lock assembly itself is faulty, it will need to be replaced to clear the error.

A reset may temporarily clear the Err1 display, but if the underlying cause such as a faulty lock, broken wiring, or a misaligned latch is still present, the error will return as soon as you attempt to run a cycle. A reset is not a fix and the root cause must be addressed.
