Symptom / Description

FAULT

Haier I-Pro Shine / Washlogix Ultra Silence Dishwasher: Water fill solenoid valve circuit fault E01; power board detects open circuit across inlet solenoid coil.

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: Burned inlet valve coil (~3.8 kΩ nominal), corroded connector spade terminals, or broken wire in door hinge harness.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Measure inlet valve coil resistance (~3.5–4.5 kΩ). Inspect wiring harness continuity from control board. Replace valve assembly if coil is infinite ohms. 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 E01

FAQ TREE

What does error code E01 mean on a Haier appliance?

Haier error code E01 indicates: Haier I-Pro Shine / Washlogix Ultra Silence Dishwasher: Water fill solenoid valve circuit fault E01; power board detects open circuit across inlet solenoid coil..

What is the root cause of Haier error code E01?

The primary root cause for Haier code E01 is: On Haier dishwashers powered by I-Pro Shine Ultra Silence brushless wash circulation pump, dual-zone inverter spray system, and micro-filtration: Burned inlet valve coil (~3.8 kΩ nominal), corroded connector spade terminals, or broken wire in door hinge harness..

How do I fix or resolve Haier error code E01?

To resolve error code E01: Measure inlet valve coil resistance (~3.5–4.5 kΩ). Inspect wiring harness continuity from control board. Replace valve assembly if coil is infinite ohms. 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 E01 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Haier code E01 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: Burned inlet valve coil (~3.8 kΩ nominal), corroded connector spade terminals, or broken wire in door hinge harness. must be inspected or replaced.

How do I test electrical resistance for Haier code E01 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 E01?

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.
