Frigidaire Dishwasher iE0 Error Code

When IE0 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 IE0 calls are resolved without parts: remove lower filter and wipe sensor lens. 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 IE0 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.
