Samsung Dishwasher Error Code FE — What It Means & How to Fix It

What Does This Error Mean?

The FE error means your Samsung dishwasher has overfilled with water. Too much water entered the tub and triggered the overflow protection. The machine shuts down automatically to prevent flooding.

Affected Models

DW80R5061US
DW80R9950UG
DW80N3030US
Most Samsung built-in dishwashers

Common Causes

The water inlet valve is stuck open and won't shut off
The water level sensor (pressure switch) failed and gave the wrong signal
The float switch inside the tub is stuck in the down position
Low water pressure followed by a surge caused overfilling
A faulty control board keeps the fill cycle running too long

How to Fix It

Turn off the dishwasher and shut the water supply valve under the sink.

This stops any more water entering the machine immediately.
Open the door carefully and scoop or sponge out excess water from the tub.

Towels on the floor are a good idea — water may spill when you open the door.
Unplug the dishwasher and wait 15 minutes.

This resets the control board and water level sensor.
Check the float switch inside the bottom of the tub.

It looks like a small plastic cap or dome. Lift it up and down — it should move freely. If it's stuck down, water can't stop.
Plug back in, re-open the water supply, and run a short test cycle.

Watch the first few minutes of filling. If water keeps rising past normal, stop immediately and call a technician.

When to Call a Professional

FE involves a failed valve or sensor — both require disassembly. Do not restart the dishwasher until the standing water is removed. Repair costs for inlet valve or sensor replacement: $120–$280. A technician can identify the exact component that failed.

Frequently Asked Questions

Is FE the same as OC on Samsung dishwashers?

They are very similar. Both mean too much water. FE typically triggers when the overflow threshold is breached. OC is a separate overflow sensor at a slightly different level. The fixes are nearly identical.

Can the FE error damage my dishwasher?

Yes, if ignored. Water overflowing the tub can reach the control board and motor. Always remove standing water and identify the cause before restarting.

What is the float switch and where is it?

The float switch is a small plastic dome inside the tub, usually at the front-left corner. As water rises, it floats up and signals the machine to stop filling. If debris traps it in the down position, the water never stops.
