Unit beeps and shows a door/basket icon or will not start, even though the basket is fully inserted (no explicit code).

Safety: Unplug before inspection.

• Check latch: Inspect the drawer latch and mating hook in the body. Replace the drawer if the latch is cracked or missing.
• Test interlock: Locate the interlock sensor (microswitch or magnetic reed switch) and test continuity when the drawer is fully inserted. Replace if it does not change state.
• Housing alignment: Ensure the front panel is not warped or loose. Tighten mounting screws and adjust as needed so the drawer seats squarely.
• Wiring: Verify the interlock wires are firmly connected to the PCB and not damaged.
