Viking Built-In Dishwasher Code Pump Flow Error (3-2): wash flow not as expected

What Pump Flow Error means

Pump Flow Error is flash pattern 3-2 on Viking Professional VDB450 and Designer DDB325 built-in dishwashers: three blinks of the Pots/Pans light, then two of the Normal Wash light. The control sees that water is not flowing through the pump as expected during the cycle. It stops the wash right away, and the dishes inside will not be properly cleaned until the cause is dealt with.

Common causes of Pump Flow Error

Wash pump not moving the expected amount of water
Clogged filter or debris restricting flow
Pump or its motor drive not performing

✓ One safe check you can try

1. Pull out the lower rack and rinse the filter at the bottom of the tub; food and labels restrict flow quickly. 2. Check that both spray arms turn freely and that nothing blocks their holes. 3. Reset the power at the breaker and run a short cycle. 4. If 3-2 returns, call us.

! Why to stop there

Flow problems can come from a blockage or from the pump itself
Opening the pump area is not a home job
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.

Pump Flow ErrorPump Flow Error questions

Is a dirty filter really enough to cause 3-2?

It can be. A packed filter restricts water to the pump. Clean it first under running water, because it costs nothing and sometimes clears the pattern.

Is this the same as a drain problem?

No. Drain errors are about water leaving. Pump flow is about water moving in the wash circuit, so the check starts with the filter and spray arms.

What if cleaning the filter does not help?

Then the pump or its drive needs testing. We confirm the cause on site and quote the part in writing before replacing anything, so you are never surprised.
