Viking Induction Cooktop Code 6: filter board error

What 6 means

On Viking Professional VICU206 and VICU266 induction cooktops, plus the hybrid VCCU106 and VCCU166 and the VISC530 induction range, code 6 reports an error on the filter board. The board may hold wrong stored data, see a permanently low voltage, have an electronic device error, or have lost its data. The cooktop treats this as a control problem, so zones commonly will not start while the 6 is showing.

Common causes of 6

Wrong data stored on the filter board
Permanently low voltage reaching the filter board
Electronic device on the filter board has failed
Filter board data lost

✓ One safe check you can try

1. Check that other appliances on the same circuit are working and that the cooktop breaker has not tripped. 2. Switch the cooktop breaker off for a minute and back on. 3. If the 6 returns, keep the cooktop switched off. The filter board is under the glass, and a low-voltage check needs instruments, so schedule a visit instead of lifting anything.

! Why to stop there

Several different board conditions share this one code
A voltage check and a board check are needed to tell them apart
We explain the finding and the price before any work and warranty it 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.

66 questions

What does the filter board do?

It sits between the incoming power and the induction electronics and cleans up the supply. Code 6 means that board reported a data, voltage or device problem.

Could my house wiring cause code 6?

A permanently low voltage is one listed reason, so we look at the supply during the visit. If the cooktop's breaker is tripping, mention that when you call.

Will you replace the board straight away?

Not before checking. We confirm the reading on site, give you a written price, and replace the board only when it is the part that is actually reporting the error.
