A faulty leak sensor can prevent the dishwasher from starting at all by sending a false leak signal to the control board, which disables operation as a safety measure.
If the sensor malfunctions, it may trigger a persistent LC or LE error code even when no actual water leak exists, causing unnecessary shutdowns.
A failed sensor that doesn't detect an active leak allows water to continue flowing into the base pan, resulting in water pooling beneath the appliance and on the kitchen floor.
An intermittently failing leak sensor can interrupt a running wash cycle by sending sporadic leak signals to the control board, halting the cycle unexpectedly.
A completely failed sensor becomes unresponsive and fails to detect genuine leaks, leaving the water supply running and risking water damage to flooring and cabinetry.
💡 Pro Tip: Is Your Leak Sensor the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Dishwasher displays a leak error code (e.g., LC or LE) but no visible water leak is present
⚠️ Dishwasher refuses to start or stops mid-cycle without explanation
⚠️ Water pooling or dripping underneath the dishwasher on the floor
⚠️ Leak detection system appears unresponsive — no error even when water is present in the base pan
🔍 Diagnostic tip: Pull the dishwasher out, remove the lower access panel, and visually inspect the base pan sensor. Use a multimeter to test for continuity — a failed sensor will read open circuit in dry conditions or shorted in wet conditions when it should not be. If the control board is known good and error codes persist, replace the sensor first — it's the lowest-cost fix.
