Symptom / Description

FAULT

Dishwasher has stopped mid-cycle and may have water in the base

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

Water leakage detected. The anti-flood switch in the base of the machine has been activated by a leak.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED
1Unplug the appliance. Carefully tilt the dishwasher forward to drain water from the base and reset the switch. Find and repair the source of the leak (e.g., split hose, bad seal).

1. Pre-Intervention Electrical Safety Protocols
  • !Electrical Safety Protocol: Isolate 230V mains power before accessing the lower pump housing.
  • !Prepare a shallow basin and absorption towels: expect 3 to 10 liters of stagnant trapped water upon filter opening.
  • !Beware of sharp foreign objects (broken glass, needles, screws) trapped inside the impeller cavity.
3. Preliminary Mechanical & Visual Checks
  • Unscrew coin trap filter and clear all foreign debris (coins, hairpins, bra underwires).
  • Rotate pump impeller manually: synchronous magnetic rotors should snap cleanly in 90° intervals without jamming.
  • Check drain hose for kinks, blockages, or unpunched sink spigots; verify drain height is between 65cm and 100cm.
