What Descaling is necessary means

On the Viking Combi Steam/Convect ovens VCSO210 and CVCSO210 (2014 to 2016), such as the VCSO210SS, and on the VSOC530SS, the message Descaling is necessary means scale has built up in the steam generator and the descale function should be run. It is a user message about upkeep. Scale reduces steam output and cooking quality over time. The oven is not broken, and the message clears after a completed descale.

Common causes of Descaling is necessary

  • Mineral scale from hard water in the steam generator
  • Many steaming cycles since the last descale
  • A descale cycle that was started and then interrupted
✓ One safe check you can try

1. Let the oven cool completely. 2. Empty the water reservoir and fill it with descaling solution as the oven instructs. 3. Start the DESCALE function and let it run to the end. 4. Rinse the reservoir and run the rinse step with fresh water. 5. If the message stays after a full cycle, call us.

! Why to stop there
  • Descaling is an owner task and needs no tools
  • An interrupted cycle must be repeated
  • A visit is useful only if the message stays after a full cycle
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.

Descaling is necessaryDescaling is necessary questions
What does descaling do?

It dissolves mineral scale in the steam generator so steam output and heating stay normal. Without it, the scale thickens over time and the generator has to work harder to make steam.

Can I use vinegar instead?

Use only the descaler the oven's instructions name. Other products may harm seals or leave residue in the water lines. If you are unsure, call us before you start the cycle.

The oven still asks for descaling.

Make sure the cycle ran to the end and the rinse was done. If the message stays, we inspect the steam generator, with a written price first and a 30-day workmanship warranty.
