Symptom / Description

FAULT

Haier I-Pro Shine / Washlogix Ultra Silence Dishwasher: Fill meter pulse count error E02; turbine sensor signals water fill but pulse frequency is erratic or dropping out.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

On Haier dishwashers featuring I-Pro Shine Ultra Silence brushless wash circulation pump, dual-zone inverter spray system, and micro-filtration: Magnet pin loose in flowmeter impeller, limescale accumulation inside water jacket labyrinth, or oxidized plug contacts.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Inspect left-side plastic air break for scale deposits. Clean electrical contacts on reed switch PCB with contact spray. Replace air break if impeller sticks. 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: Disconnect electrical power before touching solenoid valve coils or Aquastop connectors.
!Firmly shut off the domc water supply tap before unscrewing the inlet hose fitting.
!Check safety base drip tray for accumulated water triggering the anti-flood polystyrene float switch.

3. Preliminary Mechanical & Visual Checks

Remove and clean sediment and sand particles from the 3/4" inlet hose metal mesh filter.
Verify domestic dynamic water pressure is between 1.0 and 10.0 bar (0.1 to 1.0 MPa).
Inspect outer Aquastop hose jacket for expansion, pinch damage, or internal leak reservoir triggering.

Frequently Asked Questions: Haier E02

FAQ TREE

What does error code E02 mean on a Haier appliance?

Haier error code E02 indicates: Haier I-Pro Shine / Washlogix Ultra Silence Dishwasher: Fill meter pulse count error E02; turbine sensor signals water fill but pulse frequency is erratic or dropping out..

What is the root cause of Haier error code E02?

The primary root cause for Haier code E02 is: On Haier dishwashers featuring I-Pro Shine Ultra Silence brushless wash circulation pump, dual-zone inverter spray system, and micro-filtration: Magnet pin loose in flowmeter impeller, limescale accumulation inside water jacket labyrinth, or oxidized plug contacts..

How do I fix or resolve Haier error code E02?

To resolve error code E02: Inspect left-side plastic air break for scale deposits. Clean electrical contacts on reed switch PCB with contact spray. Replace air break if impeller sticks. 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 E02 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Haier code E02 persists, the physical component causing On Haier dishwashers featuring I-Pro Shine Ultra Silence brushless wash circulation pump, dual-zone inverter spray system, and micro-filtration: Magnet pin loose in flowmeter impeller, limescale accumulation inside water jacket labyrinth, or oxidized plug contacts. must be inspected or replaced.

How do I test electrical resistance for Haier code E02 using a multimeter?

Set a digital multimeter to ohms (Ω). Disconnect power and test Solenoid Valve Coil / Aquastop Pneumatic Valve across Across coil spade terminals (disconnect harness first). Expected nominal reading is 3.5kΩ–4.5kΩ (Standard 230V) / 2.0kΩ–4.2kΩ (Aquastop). Tolerance: ±10%. Open circuit (OL) indicates burned solenoid coil. Flowmeter turbine reed switch pulses on flow..

What safety protocol must be followed before servicing Haier code E02?

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.
