What to do when Descale Unit. Check manual. shows on the home appliance

Kind of codeScale and descaling

Minerals from the water supply have built up where the appliance heats or freezes water: a steam oven's generator, a built-in coffee system, a dishwasher's heating path, an ice maker's mold and valve. The appliance asks for a descale because scale slows heating and blocks small passages. Run the descaling program with the descaler the maker names, check the water-hardness setting against your local water, and put the next descale on the calendar.

Usually leads toWater filter and descaling service

Fresh filters in dispensers and ice makers, and scale cleared from steam ovens, ice makers and dish care machines.

Shows up asWhite Scale on Appliance Water Parts: Steam Ovens, Ice Makers, Dish Care

White scale on appliance water parts is a chalky white or tan crust on a steam oven tray, an ice mold or plate, a dispenser outlet or the inside of a dishwasher, left by hard water.

MakeCove

Cove makes only dishwashers, so a Cove visit is all dish care: filters and spray arms cleaned, the door gasket checked and the water supply and drain inspected.

Questions
about Descale Unit. Check manual..

Can I clear Descale Unit. Check manual. myself?
Follow the descale steps in the appliance's own use and care guide. If it comes back, it needs a visit.
How often should a Cove appliance be descaled?
The guide ties the message to hard-water buildup rather than a fixed schedule, so households on hard water should expect to see it more often than those on softened water.
Can plain white vinegar be used instead?
Cove's own guide names a dishwasher cleaner or citric acid specifically; check the descale section of the guide before substituting a different household product.
Is streaking on glassware related to this message?
Cove's troubleshooting lists streaks or spots as a separate issue addressed by rinse aid dosing, so descaling and rinse-aid dosing are two different fixes for two different symptoms.
