Answer to continue safely
Is it safe to keep using?
No. An FE code indicates a risk of overflow and water damage to floors and cabinetry. Do not run the dishwasher until the cause is identified and fixed. Turn off the water supply in the meantime.
Can I reset the code?
Yes. Resetting the dishwasher will not fix an FE code if the inlet valve is stuck open or the level sensor is faulty. The underlying hardware issue must be repaired first or the FE code will recur and overflow may result.
When to stop immediately?
Stop if you notice: Water is actively leaking onto the kitchen floor from the dishwasher., Water continues to enter the tub even when the dishwasher is powered off..
Symptoms You May Notice
Water Visible at or Above the Door Seal Level
The water level inside the tub is unusually high — you may see water near the door gasket or even seeping out when the door is opened.
FE Code on Display
The control panel shows FE and the dishwasher automatically activates the drain pump to remove excess water.
Water Running Into Dishwasher When Off
You can hear water trickling into the tub even when the dishwasher is not running a cycle, indicating an inlet valve stuck open.
Complete operational failure
The dishwasher stops functioning entirely — it will not start, respond to controls, or complete any cycle until the underlying fault is resolved.
Possible Causes
Water Inlet Valve Stuck Open
Debris lodged in the valve seat or a failed solenoid diaphragm keeps the valve open, allowing continuous water flow into the tub.
Requires ProfessionalFaulty Float Switch or Water Level Sensor
The float switch or pressure-based water level sensor that signals 'full' to the control board is stuck or failed, so filling continues unchecked.
Requires ProfessionalExcess Suds from Wrong Detergent
Regular dish soap or hand soap used instead of automatic dishwasher detergent generates foam that raises the apparent water level and triggers the overfill sensor.
DIY PossibleSafe Checks You Can Do
-
1
Turn Off the Water Supply Immediately
Close the hot water shut-off valve under the sink that feeds the dishwasher. This stops any further water entering the machine and prevents floor damage while you diagnose the cause.
-
2
Check for Soap Suds
Open the dishwasher door (carefully — water may be near the top) and look for excessive foam. If suds are present, you may have used the wrong detergent. Run a rinse-only cycle with a cup of white vinegar to cut the suds, then try a normal cycle with correct detergent.

Test Whether Water Enters When Machine Is Off
With the dishwasher off and the water supply reopened, listen and look for water trickling into the empty tub. If water flows when the machine is off, the inlet valve is stuck open and must be replaced before further use.
When to Call a Professional
Contact a qualified technician if:
- Inlet valve solenoid tests normal but water still flows when de-energized (valve seat failed).
- Float switch or turbidity/pressure sensor does not change state at high water level.
- Control board is not sending shut-off signal to inlet valve at correct water level.
