Frigidaire Oven F16 Error Code

When F16 appears on a Frigidaire oven, the control board has confirmed that water did not leave the machine within the programmed drain window. On Frigidaire FGEH3047VF, Frigidaire FPEH3077RF, 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 F16 calls are resolved without parts: order ui and erc together. 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 F16 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.
