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

  1. Stop using the dishwasher – Do not run it again until the leak source is identified.
  2. Unplug or cut power – Turn off power at the circuit breaker.
  3. Check the door gasket – Inspect the entire perimeter of the door gasket for cracks or areas where it has separated.
  4. 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.
