What Does Error Code FL Mean on a GE Appliances Dishwasher?

Flood switch activated — water in base tray.

The FL code fires when the anti-flood float switch in the base pan lifts, signaling accumulated water beneath the tub. The control cuts the wash cycle and often activates the drain pump to protect against overflow. Unlike drain-fault codes such as OE or a leak-detection code like C5, FL specifically means liquid has reached the base tray sensor — whether from a worn door seal, oversudsing, a loose internal hose, or a cracked tub. It stays latched until the sensor dries.

Models affected: GE built-in dishwashers with a base-tray flood switch, including models such as GDF630PSMSS, GDT665SSNSS, and GDP630PYRFS

What owners report: Owners commonly report FL appearing mid-cycle or after switching detergents, and it often clears once the base is drained and dried. A frequent false trigger is oversudsing from regular dish soap or too much detergent, so many find the quick win is simply drying the pan and cutting back detergent before assuming a hardware leak.

Frequently Asked Questions

Can I keep using my GE Appliances Dishwasher when error FL appears? +

It is not advisable. The dishwasher may still power on, but running it while FL is active can worsen the leak fault or damage related parts. Treat it as a soon-as-possible repair.

What most commonly causes FL on a GE Appliances Dishwasher? +

Across reported GE Appliances dishwasher repairs, the most frequent is door seal damaged or worn (35% of cases), detergent oversudsing causing overflow (30%), then loose hose connection inside dishwasher (25%). Check them in that order before replacing any parts.

FL keeps coming back after a reset — what should I check next? +

A reset only clears the stored FL fault; if it returns, the leak problem is still present. Move on to the physical checks — tilt unit to drain base, then inspect door seal — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.

How much does it cost to fix GE Appliances Dishwasher error FL? +

A DIY repair typically runs $0–$100 in parts, versus $150–$340 for a professional service call, so handling it yourself saves around $150. Expect the work to take roughly 30–60 minutes.

Which GE Appliances Dishwasher models show error FL? +

FL is documented on GE built-in dishwashers with a base-tray flood switch, including models such as GDF630PSMSS, GDT665SSNSS, and GDP630PYRFS. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
