Frigidaire Dishwasher i30 Error Code
Leak detected in base pan
What this error means
i30 means water collected in the bottom pan and lifted the styrofoam float. The drain pump may run continuously as an anti-flood measure.
How I30 is detected
When I30 appears on a Frigidaire dishwasher, the control board has confirmed that water did not leave the machine within the programmed drain window. On Frigidaire FGID2479SF, Frigidaire FDPH4316AS, and similar variants, the drain pump runs for a fixed interval—often three to seven minutes on washers and dishwashers—while a pressure switch or turbidity sensor verifies the tub or sump is empty. If water remains, the cycle stops to prevent spin with a full tub or overflow on the next fill.
Most I30 calls are resolved without parts: shut off power and water. Restricted drain paths mimic pump failure because the impeller spins against a blocked hose or filter. Document whether the pump hums audibly during the drain step; a humming pump with no water movement points to a clogged filter or kinked hose, while silence may indicate a failed pump motor or loose wiring at the harness.
After clearing blockages, run a short cycle and listen at the drain hose for steady water flow. If I30 returns on the next load with a clean filter and straight hose, measure resistance at the pump motor connector per the service manual for your model before ordering a replacement pump assembly.
Common causes
- Loose drain hose clamp at sink
- Door gasket tear
- Over-suds pushing water past seal
- Cracked inlet valve body
Step-by-step fixes
- 1Shut off power and water
- 2Remove toe kick and dry the pan with towels
- 3Confirm float drops freely when dry
- 4Inspect door seal and under-sink hose clamps
When to call a technician
Water returns to pan after drying—trace leak before replacing control.
Affected models
- Frigidaire FGID2479SF
- Frigidaire FDPH4316AS
- Frigidaire FFCD2413US
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use dishwashers to prevent I30 from lint and food debris buildup.
- Record when I30 appears in the cycle and whether it clears after a 60-second power reset on your Frigidaire dishwasher—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for I30; Frigidaire uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting I30; reversed plugs on pumps and valves cause immediate repeat faults.
