Symptom / Description

FAULT

Frigidaire Gallery / OrbitClean Wash Dishwasher: Water drain timeout error i20; wash water remains in sump after 90 seconds of drain pump activation.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

On Frigidaire (Frigidaire Gallery / OrbitClean Wash Dishwasher) models: Clogged fine mesh filter in tub sump, lemon seeds or broken glass jammed in drain impeller, kinked waste hose, or drain pump coil open (160–220 Ω).

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Remove sump filter cylinders and clean under hot water. Check drain pump impeller through sump cavity. Measure pump motor resistance (160–220 Ω). Press and hold Cancel / Drain for 3 seconds, or cycle the control lock for 5 seconds to clear persistent memory fault log.

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: Frigidaire I20

FAQ TREE

What does error code I20 mean on a Frigidaire appliance?

Frigidaire error code I20 indicates: Frigidaire Gallery / OrbitClean Wash Dishwasher: Water drain timeout error i20; wash water remains in sump after 90 seconds of drain pump activation..

What is the root cause of Frigidaire error code I20?

The primary root cause for Frigidaire code I20 is: On Frigidaire (Frigidaire Gallery / OrbitClean Wash Dishwasher) models: Clogged fine mesh filter in tub sump, lemon seeds or broken glass jammed in drain impeller, kinked waste hose, or drain pump coil open (160–220 Ω)..

How do I fix or resolve Frigidaire error code I20?

To resolve error code I20: Remove sump filter cylinders and clean under hot water. Check drain pump impeller through sump cavity. Measure pump motor resistance (160–220 Ω). Press and hold Cancel / Drain for 3 seconds, or cycle the control lock for 5 seconds to clear persistent memory fault log.

Is it safe to clear Frigidaire error code I20 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Frigidaire code I20 persists, the physical component causing On Frigidaire (Frigidaire Gallery / OrbitClean Wash Dishwasher) models: Clogged fine mesh filter in tub sump, lemon seeds or broken glass jammed in drain impeller, kinked waste hose, or drain pump coil open (160–220 Ω). must be inspected or replaced.

How do I test electrical resistance for Frigidaire code I20 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 Frigidaire code I20?

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.
