Viking Built-In Dishwasher Code Current Sense Error (5-4): motor current reading problem

What Current Sense Error means

On Viking Professional VDB450 and FDB451 built-in dishwashers with the second-generation control, flash pattern 5-4 is a Current Sense Error: five flashes of the Pots/Pans light, then four of the Normal Wash light. The control is not getting a normal electrical current reading from the circuit it monitors while running. It is a service-level code, so expect the cycle to stop and the lights to repeat.

Common causes of Current Sense Error

Current-sensing circuit on the control reading incorrectly
Wiring or connection problem in the monitored circuit
Control board needing replacement

✓ One safe check you can try

1. Switch the dishwasher's breaker off for one minute, then restore power. 2. Hold START for four seconds and run a short cycle. 3. If the 5-4 lights return, stop using the dishwasher. This code reports on the dishwasher's electrical monitoring, so we do not recommend more resets or opening any panel.

! Why to stop there

A current-sense reading can only be verified with meters on a live circuit
The cause could be wiring or the control, and the wrong guess is expensive
We tell you the price in writing before we begin and cover the repair 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.

Current Sense ErrorCurrent Sense Error questions

What is the control measuring?

It watches the electrical current of the circuit it drives. Pattern 5-4 means that reading is not in the range it expects, so it stops the cycle to be safe.

Can I try the cycle again?

One reset from the breaker is fine. If the lights return, additional starts will not help, and we would rather you leave it off until we look.

Is a visit really needed?

Yes, since the check requires measuring the circuit and, if needed, opening the dishwasher. Resets and filter cleaning do not affect an electrical monitoring code.
