Answer to continue safely
Is it safe to keep using?
No. F6E4 indicates an active water leak. Operating the dishwasher risks water damage to flooring, cabinetry, and subfloor. Do not use until the leak is repaired.
Can I reset the code?
No. The fault will return immediately if any water remains in the base tray or the leak has not been fixed. The base tray must be fully dry and the leak source repaired before the sensor will clear.
When to stop immediately?
Stop if you notice: Stop all use immediately — F6E4 always means water is or was leaking inside the appliance and continued operation will cause water damage., Stop DIY investigation if water has reached electrical components in the base — disconnect power and call a technician immediately..
Symptoms You May Notice
Water pooling under or in front of the dishwasher
Visible water on the kitchen floor in front of or beneath the dishwasher is the clearest physical sign of the internal leak that triggered F6E4.
Drain pump runs continuously after cycle ends
The anti-flood response keeps the drain pump running non-stop to evacuate the base tray — you will hear a constant hum even when no cycle is active.
Cycle stops abruptly mid-wash
The dishwasher halts immediately when the base sensor detects water, regardless of what stage the wash cycle was in.
Musty smell or wet base panel
A musty odor from underneath the dishwasher or a damp kick plate panel suggests water has been collecting in the base drip tray for some time.
Possible Causes
Damaged or dislodged door gasket
A cracked, torn, or improperly seated door gasket allows water to spray past the door seal and drip into the base drip tray during the wash cycle.
DIY PossibleLoose or cracked internal hose connection
Hose clamps at the sump, circulation pump, or inlet valve can loosen over time, allowing water to drip into the base at high wash pressure.
Requires ProfessionalFailed pump shaft seal
The seal around the circulation pump shaft degrades with age and hard water exposure, allowing water to bypass the pump housing and enter the base.
Requires ProfessionalSafe Checks You Can Do
-
1
Allow drain pump to complete its cycle
Do not interrupt the drain pump after F6E4 appears. Let it run until it stops on its own (usually 2–3 minutes). Then disconnect power at the breaker before inspecting.
Tilting the dishwasher backward 45 degrees can help gravity drain water from the base tray faster, resetting the float sensor so you can run a short test cycle to identify the leak location.

2
Inspect the door gasket
With the door open, carefully run your fingers around the full perimeter of the rubber door gasket, pressing it into its channel and checking for any section that lifts away, feels brittle, or shows visible cracks.
A common failure point is the bottom corners of the gasket, where it bends sharply and is under the most stress during the wash cycle.

3
Remove kick plate and check for water stains
Remove the lower kick plate (usually two screws) and shine a flashlight into the base. Look for water stains, white mineral deposits, or wet insulation that indicate where water has been leaking.
Fresh water indicates an active leak; dried mineral rings indicate a past or intermittent leak — both require a proper repair before the dishwasher is used again.
When to Call a Professional
Contact a qualified technician if:
- Any internal leak beyond the door gasket — including pump seals, sump hoses, and inlet valve connections — should be diagnosed and repaired by a certified technician.
- If water has entered the base pan insulation, a technician can assess whether the insulation pad needs replacement to prevent mold and odor.
- A professional can pressure-test the internal hose circuit to pinpoint intermittent leaks that are not visible during a static inspection.
