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: Sekom AL02

FAQ TREE

What does error code AL02 mean on a Sekom appliance?

Sekom error code AL02 indicates: Water Inlet Timeout Error.

What is the root cause of Sekom error code AL02?

The primary root cause for Sekom code AL02 is: Alternative code for the appliance failing to fill with water..

How do I fix or resolve Sekom error code AL02?

To resolve error code AL02: Check water supply tap is open. Inspect inlet hose for kinks. Clean the filter screen on the water inlet valve.

Is it safe to clear Sekom error code AL02 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Sekom code AL02 persists, the physical component causing Alternative code for the appliance failing to fill with water. must be inspected or replaced.

How do I test electrical resistance for Sekom code AL02 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 Sekom code AL02?

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.
