Symptom / Description

FAULT

The wash cycle takes longer than expected, with frequent pauses, and excessive suds are visible in the drum.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

Excessive foam production has been detected, usually due to an overdose of detergent or the use of an unsuitable product. The device activates additional rinse cycles to reduce it.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED
1Run an empty rinse program to remove excess suds. For future uses, reduce the quantity of detergent, adapting it to the hardness of the water and the load of laundry. Choose a high-efficiency (HE) detergent.

1. Pre-Intervention Electrical Safety Protocols
  • !Electrical Safety Protocol: Disconnect electrical mains plug or trip dedicated circuit breaker before servicing.
  • !Wait at least 5 minutes before opening any casing panels to reset volatile microcontrollers and bleed residual charges.
  • !Operate in a dry workshop environment; never bypass internal electrical thermal cutouts.
3. Preliminary Mechanical & Visual Checks
  • Check appliance leveling with a spirit level; adjust threaded leveling feet for perfect stability.
  • Check door and lid perimeter rubber gaskets for tears, gaps, or foreign object obstruction.
  • Inspect shock absorbers, suspension springs, and rubber dampers for mechanical fatigue or excessive play.
Perform these diagnostic steps before triggering AI Deep Search or replacing boards.Certified Workshop Routine
