Symptom / Description

FAULT

H-Koenig E02: Water inlet / filling timeout in Washing Machine; appliance fails to fill to minimum operational level.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

The machine failed to fill with water in the expected time. This could be due to a closed water tap, kinked inlet hose, low water pressure, or a faulty inlet valve.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED
1Check that the water supply tap is fully open. Straighten the inlet hose. Clean the filter in the end of the inlet hose. If the problem persists, check the water inlet valve.

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
