Symptom / Description

FAULT

Haier I-Pro Shine / Washlogix Ultra Silence Dishwasher: Drain evacuation timeout E3; water remains in sump after 240 seconds of drain pump operation.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

On Haier dishwashers powered by I-Pro Shine Ultra Silence brushless wash circulation pump, dual-zone inverter spray system, and micro-filtration: Blocked microfilter, foreign body (glass shard, olive pit) jamming drain impeller, kinked hose, or open pump motor (~160–220 Ω).

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Remove sump filters and clean thoroughly. Check drain pump impeller for free rotation. Measure drain pump winding resistance (~160–220 Ω). Press Power button off, hold Half Load and Start buttons together while powering on until diagnostic test mode 01 displays, 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: Haier E3

FAQ TREE

What does error code E3 mean on a Haier appliance?

Haier error code E3 indicates: Haier I-Pro Shine / Washlogix Ultra Silence Dishwasher: Drain evacuation timeout E3; water remains in sump after 240 seconds of drain pump operation..

What is the root cause of Haier error code E3?

The primary root cause for Haier code E3 is: On Haier dishwashers powered by I-Pro Shine Ultra Silence brushless wash circulation pump, dual-zone inverter spray system, and micro-filtration: Blocked microfilter, foreign body (glass shard, olive pit) jamming drain impeller, kinked hose, or open pump motor (~160–220 Ω)..

How do I fix or resolve Haier error code E3?

To resolve error code E3: Remove sump filters and clean thoroughly. Check drain pump impeller for free rotation. Measure drain pump winding resistance (~160–220 Ω). Press Power button off, hold Half Load and Start buttons together while powering on until diagnostic test mode 01 displays, then power off.

Is it safe to clear Haier error code E3 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Haier code E3 persists, the physical component causing On Haier dishwashers powered by I-Pro Shine Ultra Silence brushless wash circulation pump, dual-zone inverter spray system, and micro-filtration: Blocked microfilter, foreign body (glass shard, olive pit) jamming drain impeller, kinked hose, or open pump motor (~160–220 Ω). must be inspected or replaced.

How do I test electrical resistance for Haier code E3 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 Haier code E3?

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.
