Possible Causes

Basket not detected, Overheat sensor latched, Firmware lock after previous fault, Faulty buzzer/alert circuit

How to Fix / Troubleshooting

Safety first: Unplug the unit before internal checks.

  • Power cycle: Unplug for at least 5 minutes to reset internal protections.
  • Check basket and door: Remove and firmly reinsert the basket until it clicks. Ensure nothing obstructs closure.
  • Inspect basket switch: Test the microswitch for proper operation and replace if faulty.
  • Check sensor and thermal fuse: If the unit overheated previously, the thermal fuse or high-limit thermostat may be open, causing a lockout. Test and replace as needed.
  • Service if unresolved: If beeping persists with no clear cause, the main PCB firmware or logic may be faulty and require replacement.
