Melitta Caffeo Barista T Replace grindstones

Inleiding

When the coffee becomes weak, the grindstones may be worn out (after about 10,000 brews). The grindstones are not sharp enough to grind the coffee cleanly, the beans are only crushed and not cut.

Note: From step 12 onwards, the identical grinder from Jura is shown, there may be slight visual differences, but this does not matter for the repair.
