Symptom / Description

FAULT

The appliance stops mid-cycle, particularly during demanding phases like spinning, and refuses to restart immediately.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

The motor thermal protector (Klixon) has tripped due to overheating. This can be caused by an overload of laundry, a mechanical blockage or an internal motor fault.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED
1Allow the appliance to cool for at least 30 minutes. 2. Check that the laundry load is not excessive. 3. Restart the program. 4. If the error recurs with normal load, check that the motor has no hard spots by turning it by hand (machine unplugged). 5. Clean the engine ventilation grilles.

1. Pre-Intervention Electrical Safety Protocols
  • !Electrical Safety Protocol: Cut electrical mains power. Never measure resistance on energized heating circuits.
  • !Ensure tub water or heating cavity is completely drained and cool to the touch before dismantling.
  • !Verify absolute zero voltage using an approved 2-pole voltage detector before touching element terminals.
3. Preliminary Mechanical & Visual Checks
  • Inspect heating element tube for calcification buildup, bulging, pinholes, or blistering.
  • Check wiring spade terminals for heat discoloration, burnt insulation, or loose crimps.
  • On thermal Klixon switches: check for manual red reset buttons and verify spring-loaded snap action.
