What E15 Means
E15 means the dishwasher's safety float switch has detected water pooled in the base pan and the AquaStop leak-protection system has shut off the water inlet to prevent flooding.
Common Causes of E15
- A genuine leak from a hose, seal, or pump
- A stuck or faulty base-pan float switch (false trigger)
- Excess condensation collecting in the base pan over time
🔧 One Safe Check You Can Try
Turn off the water supply to the dishwasher at the shutoff valve, tilt the unit forward slightly if safely possible to check for standing water in the base, and do not run the cycle again until the leak source is found.
⚠ Why You Shouldn't Go Further Than That
- Disabling or resetting the float switch to get the dishwasher running again removes the exact safety feature keeping water off your kitchen floor.
- A leak that isn't fully diagnosed and stopped can travel under cabinetry for days before it becomes visible, causing far more damage than the original fault.
- The base pan sits directly beneath live electrical connections — checking for standing water without shutting off the breaker first is a shock risk.
- Tilting or moving the unit to inspect the base pan can shift or damage hose connections that were previously fine.
- Continuing to run cycles while chasing this fault yourself risks water damage that most homeowners insurance treats as a maintenance issue, not a covered loss.
