What we can confirm
Code 3-1, from the manufacturer's own documentation
A code is only meaningful together with the generation showing it — the same two digits mean different things across generations, and that is the commonest reason a code looked up online leads somewhere wrong. This one is recorded on 301 Series, 324 Series, 451 Series.

What it looks like from the kitchen
The symptom this code usually arrives with
A code names the subsystem; the symptom is what sent you to look at the display in the first place. That page says what it usually turns out to be, cheapest cause first.
-
Door, latch, and the four-second reset Dishwasher will not start
A machine that does nothing when the cycle is selected, or starts and stops immediately. Two of the causes are free to check and one of them is a habit rather than a malfunction.
- Nothing happens when START is pressed
- The start light blinks and nothing runs
- It runs for a moment and stops
On the same generation
What else belongs to the 301 Series
A code belongs to a generation rather than to one cabinet. These are the other codes yours can show, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.
Other codes this generation can display
Pan flood sensor
Motor control status
Motor control comms
Diverter timeout
Drain error
Huba sensor
Fill timeout
Low level sensor
High level
Drain pump
Motor status
Motor under voltage

About Viking dishwasher error code 3-1
What Viking publishes for it
On a Viking dishwasher, the manufacturer publishes this for a UI to motor control communications error. That sentence is Viking's own, read out of the code table in its Use and Care manual for this equipment rather than worked out from the outside. Everything below it — what the condition covers and what is worth doing first — is ours, written from what this equipment does in Miami kitchens.
Which alphabet this belongs to
Viking dishwashers do not show an error code. There is no number and there is no letter. Two lights on the front — Pots/Pans and Normal Wash — flash a count each, and the pair is the code: one flash then five is a drain problem, two then two is a fill problem.
What it covers
What a published cause names is a circuit rather than a component, which is the single most useful thing to know before anybody orders a part. This one covers:
- The harness between the door panel and the machine
- Either board
Worth trying yourself, in this order
- Hold START for four seconds and run a cycle
Then what
Two boards that cannot hear each other is most often the ribbon or the harness between them, not either board. In a coastal kitchen that harness has spent years in salt-laden air, and the connector is where that shows first.
Viking publishes this one for the built-in dishwashers — that is dishwashers on this site. The full Viking archive has the other conditions, searchable, and it is worth knowing that the same token can mean two different things on two different Viking machines, so the group above is part of the answer. We repair this equipment across Miami-Dade, Broward and Palm Beach.
