Symptom / Description

FAULT

Candy Brava / RapidÓ / DiVino Smart Touch Dishwasher: Drain evacuation alarm AL03; sump fails to empty completely during intermediate rinse drain phase.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

On Candy dishwashers powered by Brava high-pressure wash hydraulics, Maxi Tub basket architecture, and Smart Touch / hOn Wi-Fi telemetry: 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/Reset for 5 seconds until the LED rapid flash ends, close door to initiate 60s drain cycle, then power 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: Candy AL03

FAQ TREE

What does error code AL03 mean on a Candy appliance?

Candy error code AL03 indicates: Candy Brava / RapidÓ / DiVino Smart Touch Dishwasher: Drain evacuation alarm AL03; sump fails to empty completely during intermediate rinse drain phase..

What is the root cause of Candy error code AL03?

The primary root cause for Candy code AL03 is: On Candy dishwashers powered by Brava high-pressure wash hydraulics, Maxi Tub basket architecture, and Smart Touch / hOn Wi-Fi telemetry: 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 Candy 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/Reset for 5 seconds until the LED rapid flash ends, close door to initiate 60s drain cycle, then power off.

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

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Candy code AL03 persists, the physical component causing On Candy dishwashers powered by Brava high-pressure wash hydraulics, Maxi Tub basket architecture, and Smart Touch / hOn Wi-Fi telemetry: 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 Candy 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 Candy 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.
