Symptom / Description

FAULT

Ignis LTE Top-Loader & TuttoinUno Front-Loader Washing Machine: Motor stator tap field weakening failure F28; high-speed spin field switching relay does not engage.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

On Ignis washers: Open circuit in stator intermediate winding tap, broken motor wiring harness terminal, or defective field-weakening relay.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Measure resistance across stator tap winding connections on motor terminal block (nominal 1.2–2.5 Ω). Check 12V DC coil activation on field relay. Hold Start/Cancel button for 5 seconds until indicator light turns solid, switch off, and turn knob to 0.

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: Ignis F28

FAQ TREE

What does error code F28 mean on a Ignis appliance?

Ignis error code F28 indicates: Ignis LTE Top-Loader & TuttoinUno Front-Loader Washing Machine: Motor stator tap field weakening failure F28; high-speed spin field switching relay does not engage..

What is the root cause of Ignis error code F28?

The primary root cause for Ignis code F28 is: On Ignis washers: Open circuit in stator intermediate winding tap, broken motor wiring harness terminal, or defective field-weakening relay..

How do I fix or resolve Ignis error code F28?

To resolve error code F28: Measure resistance across stator tap winding connections on motor terminal block (nominal 1.2–2.5 Ω). Check 12V DC coil activation on field relay. Hold Start/Cancel button for 5 seconds until indicator light turns solid, switch off, and turn knob to 0.

Is it safe to clear Ignis error code F28 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Ignis code F28 persists, the physical component causing On Ignis washers: Open circuit in stator intermediate winding tap, broken motor wiring harness terminal, or defective field-weakening relay. must be inspected or replaced.

How do I test electrical resistance for Ignis code F28 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 Ignis code F28?

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.
