This door switch is the electrical interlock that senses the door position and allows the appliance to run only when the door is closed. It restores normal door sensing to prevent unexpected operation and enable cycles to start. What it does

• Detects whether the door is closed and completes the circuit so the appliance can start or continue a cycle.
• Prevents operation when the door is open, improving safety and preventing leaks or heat loss.
• Common symptom: appliance will not start, stops mid-cycle, or shows door-related fault codes when the switch fails.
• Replaces a worn or unreliable door sensing component that causes intermittent starts or shutdowns.

• One door switch

• Disconnect power (unplug or shut off circuit breaker) before attempting replacement to avoid shock.
• Handle connectors and wiring gently; verify connector orientation before reassembly.
• Reassemble panels and test door operation and a short cycle to confirm correct function.

This flat washer secures fasteners and helps distribute clamping force to protect parts from pull-through and wear. It's a small but critical hardware piece that helps maintain proper alignment and reduce vibration in the appliance. What it does:

• Sits under a nut or bolt to evenly spread load and prevent surface damage
• Helps keep fasteners tightened and reduces loosening from vibration
• Protects mating surfaces from wear and deformation
• Can reduce rattling or vibration-related noise when used as intended

• Disconnect power and water before accessing internal components
• Replace like-for-like; do not force or modify the washer to fit
• If other hardware is corroded or damaged, replace affected fasteners as a set

This inner door frame is the metal/plastic support that mounts behind the outer door panel to hold the inner liner, latch, and components in place. Replacing a damaged frame restores proper door alignment and sealing. What it does:

• Provides structural support for the dishwasher door assembly and mounting points for the inner liner and hardware
• Helps maintain proper door alignment so the latch closes securely
• Prevents gaps that can cause water to spray toward the control area or hinge
• Reduces door rattles and vibration from a loose or bent inner frame

• One door inner frame

• Disconnect power and water supply before beginning work
• Remove exterior door panel and any attached trim to access the inner frame; keep track of fasteners
• Handle edges and clips carefully to avoid cutting yourself or damaging the door finish

This replacement protective cover shields internal appliance components from dirt and moisture to help restore proper fit and reduce the risk of damage. Use it when the original cover is cracked, warped, or missing. What it does:

• Protects underlying components from moisture, debris, and accidental contact
• Helps prevent electrical shorts or corrosion caused by water intrusion
• Restores a secure enclosure and proper alignment where the original cover failed
• Fits the original mounting points to maintain intended part protection

• Disconnect power to the appliance before starting any repair
• Remove any fasteners or clips holding the old cover and replace with the new cover using the original hardware
• Verify the cover seats flush and secures to prevent gaps that allow moisture or debris
• If wiring or insulation under the cover is damaged, replace those components before reinstalling the cover
