Viking Built-In Dishwasher Code Pan Flood Sensor Disconnect (1-1): flood sensor not connected

What Moisture Sensor Disconnect means

Flash pattern 1-1 on Viking Professional VDB450 and Designer DDB325 built-in dishwashers is Pan Flood Sensor Disconnect: one flash of the Pots/Pans light, then one flash of the Normal Wash light. The control can no longer see the moisture sensor in the base pan, so it cannot watch for leaks. It stops the cycle and waits for you to reset it.

Common causes of Moisture Sensor Disconnect

Moisture sensor connection loose or open
Sensor damaged
Control not detecting the sensor

✓ One safe check you can try

1. Turn off the breaker for the dishwasher for a minute and turn it back on. 2. Hold START for four seconds and run a short cycle. 3. If 1-1 shows again, stop using the dishwasher. The sensor is in the base pan under the tub, which you should not reach into.

! Why to stop there

The sensor is under the tub and needs panels removed
Running without leak detection is a risk
Written price first, with a 30-day warranty

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 Sensor DisconnectMoisture Sensor Disconnect questions

Is a disconnect the same as Pan Flood?

No. Pan Flood means the sensor found water in the base pan. Pattern 1-1 means the control lost contact with the sensor itself, whether or not there is any water.

Can I run the dishwasher without the sensor?

The control will not let you. It needs the sensor connected so that leak protection is in place before it starts a cycle. That protects your floor and cabinets.

Do I need a new sensor?

Not always. Often the cause is a loose connection, but we test it first. If a part is needed, we quote the price in writing before we order it.
