Moccamaster: descaling and the official cleaning routine

Technivorm backs every Moccamaster with a 5-year warranty — an industry-leading figure — but that warranty assumes basic descaling, because every drip brewer scales with hard water.

Descaling

Technivorm sells its own descaling agent through the "Filters & Cleaning" section of its official store. Frequency depends on water hardness and brew volume; the manufacturer's cleaning products come with their own instructions — follow those rather than improvising with generic acids on a handmade machine. After any descale, run full tanks of fresh water before brewing for consumption.

Routine care

• The glass carafe and hot plate: clean the carafe regularly; coffee oils bake onto hot-plate carafes and go rancid.
• The brew basket is removable on the KBGV — rinse after every brew and clean the drip-stop mechanism so it seals properly for half-pot brews.
• The water reservoir holds the brew path's first defense: use reasonably soft water and scale forms slower everywhere.

Parts availability

Official replacement parts — carafes, brew baskets, lids, and internal components — are sold directly by the manufacturer, which is unusual for a drip brewer and part of why these machines stay in service for decades.
