Viking Induction Cooktop Code 10: wrong terminal connected, supply over 400 volts

What 10 means

On Viking Professional VICU206 and VICU266 induction cooktops, the hybrid VCCU106 and VCCU166, and the VISC530 induction range, code 10 means a wrong terminal is connected. The secondary voltage of the power supply reads above 400 volts, so the supply connection has to be checked. This usually shows up soon after installation or after the cooktop was moved or rewired, and the 10 appears with no heating.

Common causes of 10

Supply connected to the wrong terminal
Supply voltage higher than the cooktop is built for

✓ One safe check you can try

1. Turn the cooktop's breaker off right away and leave it off. 2. Do not keep restarting the cooktop to see whether the 10 clears; an overvoltage supply can damage the electronics. 3. Tell us whether the cooktop was just installed or moved. We will check the connection and supply with proper meters at a visit.

! Why to stop there

Terminal and voltage checks are done with live supply and meters
Running the cooktop on the wrong supply can harm the boards
We quote the visit in writing first and warranty the work 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.

1010 questions

Why would voltage over 400 volts show up?

The cooktop reads the secondary side of its supply. A reading above 400 volts means the cable is landed on a terminal it should not be on, or the supply is not what the unit expects.

Can I just reset the breaker?

Please do not keep cycling it. A reset is not the fix here, and repeated starts on a wrong supply can stress the electronics. Leave it off until the connection is checked.

Does code 10 mean the cooktop is damaged?

Not necessarily. Caught early, it is often only a connection correction. That is why we ask you to stop using it, so a wiring mistake does not turn into a board replacement.
