# Dacor coffee system brew group service

### Bitter and weak at once is grind and group

Burrs wear and the grind drifts coarse, which under-extracts and tastes thin; scale and old coffee oils in the brew group supply the bitterness. Two causes, one complaint, and both are maintenance rather than failure. On a discontinued platform the honest part comes first: we establish that the parts exist before booking labor. Seals, burrs and the water path are the failures most likely to be solvable; boards are the difficult end, and we say which one you are facing.

What this involves

Bitter and weak together is grind and group, not beans or settings

Discontinued platform — parts are checked before labor is booked

Seals, burrs and the water path are the solvable failures

Check the parts question first

Which components this machine needs and whether they are still available. This conversation happens before the visit, not during it.

Strip and service the group

Seals, screens and the path through it. Years of oils come off with the group on a bench, not in a cabinet.

Set the grind and prove the shot

Burr condition, grind setting and an extraction that is timed. The result should be tasted, not asserted.

### Would better beans help?

They will change the taste and not the problem. With a coarse grind and a dirty group, an expensive bean tastes like a cheap one, which is the frustrating part of this problem.

### Is it worth servicing a discontinued machine?

Often, yes — a serviced group and fresh burrs transform one of these. What decides it is which parts yours needs, and that question is answered before any visit is booked.
