Symptom / Description

FAULT

Airlux I20: Water drainage failure detected in Dishwasher; drain pump cannot evacuate water within safety time limit.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

The appliance has failed to drain the water within the set time. The filters, pump, or hose are blocked.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Pause the cycle and check the main filter and microfilter inside the tub. Inspect the drain hose for kinks. Check the drain pump for foreign objects.

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: Airlux I20

FAQ TREE

What does error code I20 mean on a Airlux appliance?

Airlux error code I20 indicates: Airlux I20: Water drainage failure detected in Dishwasher; drain pump cannot evacuate water within safety time limit..

What is the root cause of Airlux error code I20?

The primary root cause for Airlux code I20 is: The appliance has failed to drain the water within the set time. The filters, pump, or hose are blocked..

How do I fix or resolve Airlux error code I20?

To resolve error code I20: Pause the cycle and check the main filter and microfilter inside the tub. Inspect the drain hose for kinks. Check the drain pump for foreign objects.

Is it safe to clear Airlux error code I20 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Airlux code I20 persists, the physical component causing The appliance has failed to drain the water within the set time. The filters, pump, or hose are blocked. must be inspected or replaced.

How do I test electrical resistance for Airlux code I20 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 Airlux code I20?

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.
