Haier Washer Error Code Err1 — Door Not Closed

Moderate Repair 10–30 minutes Tools: Phillips screwdriver, Multimeter, Torx T15 driver

What this means

Error code Err1 on Haier washers indicates the machine cannot detect that the door or lid is properly closed and locked. The washer will not begin the cycle until the door sensor confirms engagement. On front-load Haier models, the door latch or lock solenoid may be malfunctioning. On top-load models, the lid switch or actuator may have failed. Common causes include a misaligned door strike, a worn latch, a broken lid switch, debris in the door seal preventing full closure, or a faulty door lock motor.

Alternate codes: E01, Er1

Step-by-step fix

3 steps
1

Close the door firmly

Open the door fully, then close it with firm pressure until you hear it click into the locked position. On front-load models, check that no clothing or the door boot seal is caught in the door path.

On Haier front-load washers, the door must be pushed until both the latch and the electronic lock engage — listen for two distinct clicks.

2

Inspect the door latch and strike

Examine the door latch hook and the strike plate on the frame. Look for wear, bending, or accumulated detergent residue that could prevent proper engagement. Clean the strike and latch with a damp cloth.

Detergent and fabric softener residue build up on the latch area over time, creating a sticky film that prevents proper contact.

3

Test the door lock assembly

Unplug the washer. Access the door lock (behind the front panel on front-loaders or under the top panel on top-loaders). Disconnect the wire harness and test the lock solenoid and switch contacts with a multimeter. The switch should show continuity when the lock is engaged.

Haier door locks typically use a wax motor mechanism — if it takes more than 15 seconds to lock, the wax motor is failing.

When to call a professional

If the door lock, latch, and wiring all test good but Err1 persists, the main control board may have a failed door lock relay. This requires professional diagnosis and board replacement.
