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: Novomatic AL02

FAQ TREE

What does error code AL02 mean on a Novomatic appliance?

Novomatic error code AL02 indicates: Dishwasher cycle starts but no water enters the machine..

What is the root cause of Novomatic error code AL02?

The primary root cause for Novomatic code AL02 is: Water supply issue. The tap may be closed, the inlet hose kinked, or the water inlet solenoid valve has failed..

How do I fix or resolve Novomatic error code AL02?

To resolve error code AL02: Ensure the water supply tap is fully open. Check the inlet hose for kinks. Clean the filter in the hose connection. Test and replace the inlet valve if necessary.

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

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Novomatic code AL02 persists, the physical component causing Water supply issue. The tap may be closed, the inlet hose kinked, or the water inlet solenoid valve has failed. must be inspected or replaced.

How do I test electrical resistance for Novomatic 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 Novomatic 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.
