Symptom / Description

FAULT

The device interrupts its cycle at the beginning, signaling a problem with the cold water supply.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

The cold water supply valve is closed, the inlet hose is kinked, or the solenoid valve inlet filter is clogged.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED
1Check that the wall-mounted cold water faucet is fully open. 2. Make sure the supply hose is not kinked or crushed. 3. Close the tap, unscrew the hose from the device and clean the small filter located at the inlet.

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.
