What Moisture Sensor means

On Viking Professional VDB450 and Designer DDB325 built-in dishwashers, the Pan Flood warning appears when both the Pots/Pans and Normal Wash lights flash continuously. The moisture sensor in the base pan has detected water where there should be none, which usually means a leak under the tub. The dishwasher stops and waits until you reset it. Dry the area before you restart it.

Common causes of Moisture Sensor

  • Leak somewhere inside the dishwasher
  • Overflow from the tub into the base
  • Moisture sensor wet from spilled water
✓ One safe check you can try

1. Turn off the water supply under the sink and switch off the dishwasher's breaker. 2. Look at the floor and cabinet for water and dry what you can reach. 3. Restore power and hold START for four seconds to reset. 4. If Pan Flood returns or you see water, leave the supply off and call us.

! Why to stop there
  • Water in the base pan means a leak that is likely to continue
  • Finding it may mean pulling the dishwasher forward
  • We give a written price first and a 30-day warranty on the repair
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Moisture SensorMoisture Sensor questions
What is the base pan?

It is the tray under the tub that catches leaks. The sensor sits in it and raises the alarm as soon as it gets wet, before water reaches the cabinet floor.

Can a spill trigger Pan Flood?

A large spill over the door could, but a real leak is more common. If the warning returns after you dry the area and reset, assume there is a leak.

Is it safe to keep running it?

No. Shut off the water, and stop using the dishwasher until we find the source. A slow leak can damage the cabinet and the flooring before you notice it.
