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.

Frequently Asked Questions: Atlantic AL01

FAQ TREE

What does error code AL01 mean on a Atlantic appliance?

Atlantic error code AL01 indicates: Boiler operation stopped, low pressure alert.

What is the root cause of Atlantic error code AL01?

The primary root cause for Atlantic code AL01 is: System water pressure has dropped below the minimum operating level..

How do I fix or resolve Atlantic error code AL01?

To resolve error code AL01: Increase the system pressure via the filling loop to 1.5 bar. Check the system for any visible leaks.

Is it safe to clear Atlantic error code AL01 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Atlantic code AL01 persists, the physical component causing System water pressure has dropped below the minimum operating level. must be inspected or replaced.

How do I test electrical resistance for Atlantic code AL01 using a multimeter?

Set a digital multimeter to ohms (Ω). Disconnect power and test Solenoid Valve Coil / Aquastop Pneumatic Valve across Across coil spade terminals (disconnect harness first). Expected nominal reading is 3.5kΩ–4.5kΩ (Standard 230V) / 2.0kΩ–4.2kΩ (Aquastop). Tolerance: ±10%. Open circuit (OL) indicates burned solenoid coil. Flowmeter turbine reed switch pulses on flow..

What safety protocol must be followed before servicing Atlantic code AL01?

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
