Symptom / Description

FAULT

Indesit Push&Go & Extra Hygiene DFP Series Dishwasher: Optical Water Indicator (OWI) turbidity sensor failure FA; infra-red optoelectronic receiver signal distorted or disconnected.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

On Indesit dishwashers: Soil deposition on OWI prism lenses, defective phototransistor diode, or wiring harness disconnect on base sump interface.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Clean optical prism face of OWI sensor inside sump. Verify 5V DC supply and signal line to main board. Replace OWI sensor assembly if cleaning fails. Press and hold Start/Reset for 5 seconds until drain pump runs, wait 60 seconds, then power cycle ON/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: Indesit FA

FAQ TREE

What does error code FA mean on a Indesit appliance?

Indesit error code FA indicates: Indesit Push&Go & Extra Hygiene DFP Series Dishwasher: Optical Water Indicator (OWI) turbidity sensor failure FA; infra-red optoelectronic receiver signal distorted or disconnected..

What is the root cause of Indesit error code FA?

The primary root cause for Indesit code FA is: On Indesit dishwashers: Soil deposition on OWI prism lenses, defective phototransistor diode, or wiring harness disconnect on base sump interface..

How do I fix or resolve Indesit error code FA?

To resolve error code FA: Clean optical prism face of OWI sensor inside sump. Verify 5V DC supply and signal line to main board. Replace OWI sensor assembly if cleaning fails. Press and hold Start/Reset for 5 seconds until drain pump runs, wait 60 seconds, then power cycle ON/OFF.

Is it safe to clear Indesit error code FA by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Indesit code FA persists, the physical component causing On Indesit dishwashers: Soil deposition on OWI prism lenses, defective phototransistor diode, or wiring harness disconnect on base sump interface. must be inspected or replaced.

How do I test electrical resistance for Indesit code FA 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 Indesit code FA?

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.
