Symptom / Description

FAULT

Dishwasher has stopped and is beeping, may have water in the base tray.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

A water leak has been detected in the base of the appliance, triggering the anti-flood protection switch.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Disconnect power and water supply. Carefully tilt the machine to drain the base. Find and repair the source of the leak (e.g., hose, seal, pump).

1. Pre-Intervention Electrical Safety Protocols

!Electrical Safety Protocol: Isolate 230V mains power before accessing the lower pump housing.
!Prepare a shallow basin and absorption towels: expect 3 to 10 liters of stagnant trapped water upon filter opening.
!Beware of sharp foreign objects (broken glass, needles, screws) trapped inside the impeller cavity.

3. Preliminary Mechanical & Visual Checks

Unscrew coin trap filter and clear all foreign debris (coins, hairpins, bra underwires).
Rotate pump impeller manually: synchronous magnetic rotors should snap cleanly in 90° intervals without jamming.
Check drain hose for kinks, blockages, or unpunched sink spigots; verify drain height is between 65cm and 100cm.

Frequently Asked Questions: Novomatic AL01

FAQ TREE

What does error code AL01 mean on a Novomatic appliance?

Novomatic error code AL01 indicates: Dishwasher has stopped and is beeping, may have water in the base tray..

What is the root cause of Novomatic error code AL01?

The primary root cause for Novomatic code AL01 is: A water leak has been detected in the base of the appliance, triggering the anti-flood protection switch..

How do I fix or resolve Novomatic error code AL01?

To resolve error code AL01: Disconnect power and water supply. Carefully tilt the machine to drain the base. Find and repair the source of the leak (e.g., hose, seal, pump).

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

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Novomatic code AL01 persists, the physical component causing A water leak has been detected in the base of the appliance, triggering the anti-flood protection switch. must be inspected or replaced.

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

Set a digital multimeter to ohms (Ω). Disconnect power and test Drain Pump Motor Stator Coils across Across pump motor spade terminals (L-N unclipped). Expected nominal reading is 160Ω–220Ω (Sync 230V) / 20Ω–45Ω (3-Phase BLDC). Tolerance: ±10% balance. Insulation resistance between coil and motor chassis must exceed 20MΩ..

What safety protocol must be followed before servicing Novomatic 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.
