Symptom / Description

FAULT

Iberna IDI / Standard Wash System Dishwasher: Drain evacuation alarm AL03; sump fails to empty completely during intermediate rinse drain phase.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

On Iberna dishwashers powered by Standard Wash System hydraulic circuit, solenoid fill valve control, and heating element flow-through tube: Heavy grease clogs in drain hose, sink siphon nipple blocked, or drain pump motor winding weakened (~160–220 Ω).

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED
1Disconnect drain hose from under-sink siphon and verify clear bore. Flush drain hose with warm water. Measure pump motor resistance (~160–220 Ω). Press and hold Start button for 5 seconds until buzzer sounds, close door to allow pump-out cycle to complete, then switch off.

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: Iberna AL03

FAQ TREE
What does error code AL03 mean on a Iberna appliance?

Iberna error code AL03 indicates: Iberna IDI / Standard Wash System Dishwasher: Drain evacuation alarm AL03; sump fails to empty completely during intermediate rinse drain phase..

What is the root cause of Iberna error code AL03?

The primary root cause for Iberna code AL03 is: On Iberna dishwashers powered by Standard Wash System hydraulic circuit, solenoid fill valve control, and heating element flow-through tube: Heavy grease clogs in drain hose, sink siphon nipple blocked, or drain pump motor winding weakened (~160–220 Ω)..

How do I fix or resolve Iberna error code AL03?

To resolve error code AL03: Disconnect drain hose from under-sink siphon and verify clear bore. Flush drain hose with warm water. Measure pump motor resistance (~160–220 Ω). Press and hold Start button for 5 seconds until buzzer sounds, close door to allow pump-out cycle to complete, then switch off.

Is it safe to clear Iberna error code AL03 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Iberna code AL03 persists, the physical component causing On Iberna dishwashers powered by Standard Wash System hydraulic circuit, solenoid fill valve control, and heating element flow-through tube: Heavy grease clogs in drain hose, sink siphon nipple blocked, or drain pump motor winding weakened (~160–220 Ω). must be inspected or replaced.

How do I test electrical resistance for Iberna code AL03 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 Iberna code AL03?

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.
