These checks are safe for homeowners. Do not attempt to open sealed refrigerant systems, touch electrical components behind access panels, or work on gas lines — always call a licensed technician for those.
Tall items in the front of the lower rack — large pots, cutting boards, cookie sheets — can prevent the door from closing fully. Rearrange the rack so nothing protrudes above the tub opening or sticks out the front. This is the first thing to check before assuming a mechanical failure.
The strike plate is the small piece the latch hook catches on. Open the door and examine it closely — is it bent, cracked, or have worn grooves? On some models the strike is adjustable. If it's moved out of position, the latch hook can't engage.
With the door open, manually operate the latch handle several times. It should move smoothly with a firm spring return. A handle that feels mushy, doesn't spring back, or has obvious play indicates the latch mechanism needs replacement.
The door latch has two jobs: physically holding the door shut, and triggering a microswitch that tells the control board it's safe to run. If the microswitch fails, the door can be fully latched but the machine still won't start. A technician can test the microswitch with a multimeter in minutes.
No — the latch microswitch must be engaged for the cycle to run. Even if you could hold the door shut physically, the control board won't start a cycle without the switch signal. And a door held by hand during a wash cycle would leak hot water — don't attempt it.
Most dishwasher door latches last 7–12 years depending on usage frequency and how firmly the door is closed. Households that close the door forcefully or frequently will wear out latches faster. It's a wear part, not a defect, and one of the more common dishwasher repairs.
