Dishwasher Door Lock Assembly | Safety Latch Replacement OEM ISO9001
Product Overview
The dishwasher door lock assembly, also known as dishwasher door latch or door interlock switch, is a critical safety and mechanical component for all automatic dishwashers. Installed on the inner door panel, this integrated assembly combines a metal hook locking structure, reset tension spring, and safety microswitch to control the dishwasher’s start and stop operation.
This premium dishwasher door latch assembly performs two core functions: mechanical door locking and electrical safety detection. When the dishwasher door is fully closed, the metal lock hook firmly engages the cabinet strike plate to resist internal high water pressure and prevent door bouncing or water leakage during washing cycles. Meanwhile, the built-in microswitch triggers a closed-circuit signal to the main control board, allowing the dishwasher to start normal operation.

Core Product Features
•Dual Safety Protection Design — Adopts mechanical locking + electrical interlock dual structure. The dishwasher can only work when the door is completely locked, effectively preventing water spraying, scalding accidents and equipment failure caused by accidental door opening.
•High Temperature & Anti-Aging Resistance — Industrial-grade ABS plastic shell resists long-term steam erosion and high-temperature baking, avoiding shell cracking, deformation and brittle aging in humid high-temperature kitchen environments.
•Wear-Resistant Locking Structure — Reinforced stainless steel spring and thickened metal lock hook maintain stable elasticity and locking force after long-term repeated use, no jamming or failure.
•Sensitive & Stable Switch Response — High-quality microswitch ensures accurate signal triggering, effectively solving problems such as no startup, intermittent operation and false door opening alarm.
•Integrated Plug-and-Play Replacement — Standard mounting holes and wiring terminals perfectly match most mainstream dishwasher models, no wiring modification or professional debugging required for quick installation.
•Excellent Sealing & Leakage Prevention — Precise locking fit ensures tight door closure, withstands high-pressure water impact during washing, and completely avoids side leakage of washing water.
