- De-scaling
If the water system is nearly or less clogged by scale then
operate the coffeemaker a few times with vinegar or with a
10-15% solution of either vinegar-acid, citric acid or tartar
acid, into cold tap water.
Do not use other de-scaling agents
as these may harm the
appliance.
If this procedure does not restore the function, then switch
off the coffeemaker when the acid has passed through
