The Frigidaire Gallery Dishwasher i20 error code signals standing greywater that the drain system cannot remove. Clearing the blockage in the drain hose and filter assembly resolves the code for most units.
Begin troubleshooting by disconnecting power and removing the lower front panel to expose the sump area. This direct inspection often reveals debris or kinks that prevent proper flow. Further steps address the air gap and pump components if water remains after the initial clearing.
Frigidaire Gallery i20 Error Symptoms Table
The Quick Look table summarizes the most frequent symptoms tied to the i20 code on Frigidaire Gallery dishwashers. It identifies the leading mechanical suspects and assigns a difficulty rating to each repair path. Homeowners use this overview to match their specific observations before opening tools or ordering parts. The ratings help prioritize safe first actions over complex disassembly.
| Symptom | Primary Suspect | Difficulty 1-5 |
|---|---|---|
| Standing water after cycle | Clogged drain hose | 2 |
| Water in bottom after drain | Blocked filter screen | 1 |
| Gurgling during drain | Kinked air gap hose | 3 |
| No drain activation | Faulty drain pump | 4 |
Frigidaire Gallery i20 Drain Hose Obstructions
Standing greywater in a Frigidaire Gallery dishwasher usually traces to a physical obstruction rather than an electrical failure. Food particles, grease, and mineral buildup collect in the drain hose or filter screen and stop flow. A kinked hose or clogged air gap produces the same result by restricting gravity-assisted drainage. Checking these locations first avoids unnecessary part replacement.
Frigidaire Gallery i20 Drain Hose Flush
Disconnect power to the unit and pull out the lower access panel. Remove the filter screen from the sump and rinse it under hot water. Disconnect the drain hose at both ends and flush it with a garden hose to clear internal debris. Reconnect the hose without sharp bends and reinstall the filter. Run a short rinse cycle to confirm water exits completely.
Frigidaire Gallery i20 Filter Screen Debris Removal
The filter screen traps debris before it reaches the drain pump on Frigidaire Gallery models. Over time grease and particles form a mat that blocks water passage even when the hose remains open. Remove the screen by twisting the handle counterclockwise and scrub both sides with a soft brush. Rinse the screen housing to clear any remaining sediment lodged in the grooves. Reinstall the screen until it clicks firmly into place.
Frigidaire Gallery i20 Air Gap Clearing
The air gap assembly prevents backflow and maintains proper drain pressure on these dishwashers. A clogged air gap cap stops greywater from exiting the tub during the drain phase. Twist off the cap and clear the small ports with a thin wire or pipe cleaner. Flush the air gap body with water while the dishwasher runs a drain cycle to confirm flow. Replace the cap once water moves freely through the assembly.
Frigidaire Gallery i20 Drain Impeller Check
The drain pump impeller must rotate freely to expel greywater from the sump. Access the pump by removing the lower panel and the pump cover. Spin the impeller by hand to check for resistance caused by lodged debris. Clear any foreign material and test pump operation with a multimeter set to continuity. Reassemble the cover and panel once the impeller turns without binding.
Frigidaire Gallery i20 Drain Pump Replacement
Persistent i20 codes after cleaning indicate a worn drain pump or valve that requires replacement. Match the part number on the existing pump to ensure compatibility with the Frigidaire Gallery series. Install the new pump by aligning the mounting tabs and securing the wiring harness. Run a full diagnostic cycle to verify the code clears and greywater drains completely.
