Symptom / Description

FAULT

The cycle is interrupted due to a problem with the hot demineralized water (AD) inlet.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

The hot demineralized water supply is faulty: closed valve, choked pipe or clogged inlet filter.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED
1Check that the hot demineralized water circuit valve is fully open. 2. Examine the supply hose to remove any stress or kinks. 3. Check and clean the filter at the inlet of the device connection.

1. Pre-Intervention Electrical Safety Protocols
  • !Electrical Safety Protocol: Disconnect electrical power before touching solenoid valve coils or Aquastop connectors.
  • !Firmly shut off the domc water supply tap before unscrewing the inlet hose fitting.
  • !Check safety base drip tray for accumulated water triggering the anti-flood polystyrene float switch.
3. Preliminary Mechanical & Visual Checks
  • Remove and clean sediment and sand particles from the 3/4" inlet hose metal mesh filter.
  • Verify domestic dynamic water pressure is between 1.0 and 10.0 bar (0.1 to 1.0 MPa).
  • Inspect outer Aquastop hose jacket for expansion, pinch damage, or internal leak reservoir triggering.
