FAULT

Dishwasher will not start and may be beeping; anti-flood system activated.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

A leak has been detected in the base of the machine, which has activated the float switch (Aquastop system).

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED
1Unplug the appliance and check the base pan for water. Find and repair the source of the leak (e.g., loose hose, cracked tub, faulty seal). Dry the base and reset the float switch.

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

Frequently Asked Questions: Bompani E1

FAQ TREE
What does error code E1 mean on a Bompani appliance?

Bompani error code E1 indicates: Dishwasher will not start and may be beeping; anti-flood system activated..

What is the root cause of Bompani error code E1?
