the complete pump unit has to be replaced.

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.

appliance.

If this procedure does not restore the function, then switch

off the coffeemaker when the acid has passed through

condition overnight and continue/repeat the cleaning

operation. After the de-scaling procedure, operate the
