Understanding the Problem
Older dishwashers commonly develop a failing door latch: plastic breaks, the strike wears, or the switch inside the latch stops actuating. When the latch fails the door won't stay closed, the dishwasher won't start, or cycles may stop mid-cycle. Replacing the latch restores a secure door closure and reliable operation. Finding a latch that fits an older unit requires confirming the dishwasher model number and comparing mounting points, connector style, and dimensions. Many latches look similar but have different mounting tabs, actuator shapes, or electrical connectors, so a match-by-measurement or correct OEM part number is the safest route. Once you have a correct replacement, the mechanical install is straightforward: remove power, open the inner door panel, swap the latch assembly and strike, reconnect wiring, reassemble and test.
Common Symptoms
Door won't latch or stays open, dishwasher won't start or stops mid-cycle, door pops open during operation, visible broken or cracked latch plastic.
Common Causes
- Worn or broken latch assembly (plastic or metal components fractured)
- Failed door-switch/microswitch inside the latch preventing the control from sensing a closed door
- Misaligned door or worn strike tab preventing the latch from engaging

Confirm the correct replacement by writing down the dishwasher model number (usually on the door frame or tub edge), then compare the new latch's mounting holes, actuator position, and electrical connector to the old one before final installation.
Frequently Asked Questions
How do I know which latch fits my old dishwasher?
Locate the model number on the dishwasher (usually on the inner door edge or frame) and search parts lists using that model. Compare the old latch and the replacement photos/specs: mounting hole spacing, actuator orientation, and the style of the electrical connector or switch must match. If unsure, share the model number with a parts supplier or include clear photos to confirm fit.
Can I use a universal latch replacement?
Sometimes a universal latch will work if the mounting geometry and actuator position match your door and strike. However, universal kits may require drilling new holes or modifying the door and aren't guaranteed to engage door-switches correctly. For reliability, an OEM or exact-fit replacement recommended—especially for older units where alignment is critical.
