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.

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](https://vikingmiami.support/error-codes/) 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.
