Answer to continue safely
Is it safe to keep using?
No. Operating a dishwasher with an active leak risks water damage to your floor, subfloor, and cabinetry. Do not use the dishwasher until the leak source is identified and repaired.
Can I reset the code?
Yes. Resetting will not clear AE permanently — the float sensor will re-trip as soon as water re-enters the base pan. The leak must be physically repaired before the dishwasher can operate normally.
When to stop immediately?
Stop if you notice: Water is actively spreading across the floor during a cycle., The leak appears to come from below the tub or pump area, not just the door seal..
Symptoms You May Notice
Visible Water on the Floor Around the Dishwasher
A puddle or wet area on the floor at the front or sides of the dishwasher base, appearing during or after a wash cycle.
AE Code on Display
The control panel shows AE and the cycle stops immediately as the base pan float sensor trips.
Drain Pump Activates Continuously
The dishwasher's drain pump runs repeatedly in an attempt to remove water accumulating in the base pan, even when no wash cycle is running.
Water visible on the floor
Puddles or moisture appear beneath or around the dishwasher, indicating water has escaped the sealed system through a leak or overflow condition.
Possible Causes
Worn or Damaged Door Gasket
The rubber door seal has developed cracks, tears, or a flattened profile that no longer creates a watertight seal during the wash cycle.
DIY PossibleLoose or Cracked Internal Hose Connection
Hose clamps connecting internal water supply or circulation hoses have loosened over time, or the hoses themselves have cracked and are dripping into the base pan.
Requires ProfessionalFailed Pump or Sump Seal
The gasket or seal around the wash pump housing has deteriorated, allowing water to weep from the pump assembly directly into the base pan.
Requires ProfessionalSafe Checks You Can Do
-
1
Inspect the Door Gasket
Open the door and run your fingers along the full perimeter of the rubber door seal. Feel for cracks, tears, stiffness, or sections where the gasket has pulled away from the channel. A damaged gasket is easy to see and straightforward to replace.
-
2
Dry Out the Base Pan
Tilt the dishwasher slightly forward (with power off and water shut off) to drain any accumulated water from the base pan. Once the pan is dry, the float sensor will reset. This allows the unit to restart temporarily so you can observe where a new leak originates.
-
3
Check for Excess Suds
Suds overflowing from the tub can fill the base pan and trigger AE without a true leak. If you see heavy foam inside the dishwasher, you may be using non-dishwasher detergent. Switch to a low-suds automatic dishwasher detergent and run a rinse cycle.
When to Call a Professional
Contact a qualified technician if:
- Leak source cannot be identified visually from door seal or accessible hoses.
- Water is escaping from the pump housing or sump assembly.
- Tub shows cracks or corrosion that cannot be sealed with a gasket replacement.
