Symptom / Description

FAULT

The device displays a clear message requesting the filling of dosing tank 1.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

The automatic dosing system level sensor has detected that product tank number 1 is empty or below the minimum threshold.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED
1Locate dosing tank 1 (internal or external). Fill it with the appropriate chemical. If the message persists after filling, check that the level sensor (float, optical) is not blocked or dirty.

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.
Perform these diagnostic steps before triggering AI Deep Search or replacing boards.Certified Workshop Routine
