FAQ

Can a tripped GFCI outlet cause my washer not to start?

Yes, a tripped GFCI (Ground Fault Circuit Interrupter) outlet can cut power to the washer. Check the outlet and reset it if necessary.

Why does my washer make a humming noise but not start?

A humming noise may indicate a seized motor or a faulty motor coupling. Unplug the washer and check for obstructions or call a professional.

How do I reset my washer if it won't start?

Unplug the washer for 1 minute, then plug it back in. Some models may require pressing a reset button on the control panel.

Can a clogged drain hose prevent the washer from starting?

No, a clogged drain hose typically affects drainage after the wash cycle, not the starting process. Check water inlet issues instead.

What if the door seems closed but the washer still won't start?

The door latch switch might be faulty. Inspect the latch for damage or debris and clean or replace it if needed.
