Symptom / Description

FAULT

The appliance fills the tank with more water than usual for the selected program.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

The control detected a load of highly absorbent laundry and adjusted the water level to ensure optimal washing.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED
1This behavior is generally a normal adjustment. If the water level is constantly excessive, check that the pressure switch is functioning properly and that the compression chamber is not obstructed.

1. Pre-Intervention Electrical Safety Protocols
  • !Electrical Safety Protocol: Cut 230V mains power before accessing the upper chassis or pressure switch terminals.
  • !Drain appliance tub completely before disconnecting pressure switch sensing hoses.
  • !Never blow high-pressure compressed air into electronic analog pressure sensors: internal diaphragms will rupture!
3. Preliminary Mechanical & Visual Checks
  • Disconnect the silicone pressure tube from the lower air trap and inspect for soap sludge, lint, or water blockage.
  • Inspect the flexible rubber hose along its entire length for pinholes, cracks, or loose clamp fit.
  • Thoroughly flush the lower compression chamber (air dome) with hot water to dissolve detergent buildup.
Perform these diagnostic steps before triggering AI Deep Search or replacing boards.Certified Workshop Routine
