Viking Built-In Dishwasher Code Motor Status Error (3-4): wash motor status reported

What Motor Status Error means

On Viking Professional VDB450 and Designer DDB325 built-in dishwashers, flash pattern 3-4 is called Motor Status. The Pots/Pans light blinks three times, then the Normal Wash light blinks four times. The control has received a status message from the wash motor that it cannot accept as normal, so it ends the cycle. Expect a silent or stalled dishwasher with water possibly left in the tub.

Common causes of Motor Status Error

Wash motor reporting an abnormal status
Motor wiring or connection problem
Motor or its control board needing replacement

✓ One safe check you can try

1. Switch the breaker off for two minutes, then on. 2. Check the bottom of the tub for a jammed utensil or broken glass around the filter, without reaching into the sump with bare hands. 3. Run a short cycle and listen for the motor humming. 4. If 3-4 returns, stop and call us.

! Why to stop there

The motor and its drive are under the tub and need panels removed
A stalled motor and a failing board both give this pattern
We quote the work in writing first and warranty it for 30 days

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.

Motor Status ErrorMotor Status Error questions

What counts as the motor status?

It is the information the motor side sends back about speed and operation. Pattern 3-4 tells us that information was not what the control expected.

Is this the same as Motor Under Voltage?

No. Under Voltage, pattern 3-5, names a low supply to the motor. Motor Status is a general report that the motor is not behaving normally.

Why is water left in the tub?

If the motor stops mid-cycle, the pump may not run, so water stays. Switch the power off and call us instead of scooping and restarting repeatedly.
