What we can confirm
Code Er03, 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 Virtuoso 6 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.
-
Often a spill, sometimes the sun Cooktop controls locked or unresponsive
A touch panel that ignores you, or a cooktop that shuts every zone down and reports a key error. A large share of these are liquid, a cloth or direct sunlight, and every one of those is free to correct.
- The panel does not respond to touch
- A key error token in the timer window
- It only happens at a particular time of day
On the same generation
What else belongs to the Virtuoso 6 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.

Electronics disrupted
Cooktop overheated

About Viking integrated downdraft cooktop error code Er03
What Viking publishes for it
On a Viking integrated downdraft cooktop, the manufacturer publishes this for the controller keys being covered. 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
This one is a European board and it does not share a single code with the rest of the make. It writes Er and a number, or U400, and it is the only Viking cooktop that will tell you its internal bus is the 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:
- Liquid across the touch area, which is the usual one
- A pan lid, a cloth or a phone resting on the keys
Worth trying yourself, in this order
- Clear the touch strip and wipe it dry — the symbol goes as soon as the keys are free
Then what
A key condition is worth ten minutes of your own before it is worth a visit: clear the glass, dry it, and take the power off at the breaker for five full minutes. If it comes back on a clean, dry, cool top, the touch board is reading a key that is not being pressed and that is a part, not a habit.
Viking publishes this one for the the integrated induction cooktop with the downdraft in the middle — that is cooktops & rangetops 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.
