Symptom / Description

FAULT

Haier I-Pro Shine / Washlogix Ultra Silence Dishwasher: Circulation wash pump motor rotation error E07; tachometer sensor sends no pulse feedback to power inverter.

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: Jammed circulation pump rotor, detached tachometer coil or magnet, or open stator winding phase (~45–95 Ω).

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Inspect circulation pump volute chamber for foreign obstructions. Measure stator windings resistance (~45–95 Ω across phases). Verify tach coil (~100–180 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

!High-Voltage Safety Protocol & DC Bus: Wait at least 5 minutes after power cutoff to allow inverter DC bus capacitors (380V DC) to bleed down.
!Verify 0V DC across inverter filter capacitors before unplugging motor harness connectors.
!Keep hands clear of drive belt and pulleys during any manual rotation tng.

3. Preliminary Mechanical & Visual Checks

Slip off drive belt and spin drum/motor shaft by hand to check for roaring or seized ball bearings.
For universal motors: verify carbon brushes have at least 10mm remaining length and smooth contact faces.
Inspect motor suspension rubber mounts and drive belt tension/groove profile.

Frequently Asked Questions: Haier E07

FAQ TREE

What does error code E07 mean on a Haier appliance?

Haier error code E07 indicates: Haier I-Pro Shine / Washlogix Ultra Silence Dishwasher: Circulation wash pump motor rotation error E07; tachometer sensor sends no pulse feedback to power inverter..

What is the root cause of Haier error code E07?

The primary root cause for Haier code E07 is: On Haier dishwashers powered by I-Pro Shine Ultra Silence brushless wash circulation pump, dual-zone inverter spray system, and micro-filtration: Jammed circulation pump rotor, detached tachometer coil or magnet, or open stator winding phase (~45–95 Ω)..

How do I fix or resolve Haier error code E07?

To resolve error code E07: Inspect circulation pump volute chamber for foreign obstructions. Measure stator windings resistance (~45–95 Ω across phases). Verify tach coil (~100–180 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 E07 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Haier code E07 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: Jammed circulation pump rotor, detached tachometer coil or magnet, or open stator winding phase (~45–95 Ω). must be inspected or replaced.

How do I test electrical resistance for Haier code E07 using a multimeter?

Set a digital multimeter to ohms (Ω). Disconnect power and test 3-Phase Motor Windings / Tacho Generator / Carbon Brushes across Across phase pins U-V, V-W, U-W on motor harness; across tacho pins. Expected nominal reading is 3Ω–6Ω (BLDC phase U-V-W) / 60Ω–180Ω (Tacho coil) / 1.5Ω–3.5Ω (Universal stator). Tolerance: BLDC phase winding values must be strictly balanced within ±0.3Ω. Hand rotation generates 1V–4V AC on tacho..

What safety protocol must be followed before servicing Haier code E07?

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.
