What Does Monogram Dishwasher “LEAK DETECTED” Mean?
The “LEAK DETECTED” message on a Monogram dishwasher indicates that the dishwasher’s built-in leak detection system has found water in the base pan. When water accumulates in the drip tray at the bottom of the dishwasher, a float switch rises and triggers this alert. The dishwasher automatically stops, shuts off the water inlet valve, and activates the drain pump.
Do not ignore this alert — an unaddressed leak can cause water damage to your cabinetry and flooring.
Common Causes of LEAK DETECTED
- Deteriorated door gasket – The rubber door seal can crack or stiffen, allowing water to leak past during wash cycles.
- Loose or cracked internal hoses – Hoses connecting the wash pump, spray arms, and drain pump can develop cracks or loosen at clamps.
- Overfilling from a faulty inlet valve – An inlet valve that fails to close can overfill the tub, causing water to overflow into the base pan.
- Cracked sump or tub – In older units, the plastic tub or sump can develop hairline cracks.
How to Troubleshoot LEAK DETECTED
- Stop using the dishwasher – Do not run it again until the leak source is identified.
- Unplug or cut power – Turn off power at the circuit breaker.
- Check the door gasket – Inspect the entire perimeter of the door gasket for cracks or areas where it has separated.
- Allow the base pan to dry – The float switch will keep the alert active until the accumulated water evaporates or is removed. The base pan must be dry before normal operation resumes.
