# Wolf coffee system repair

### Five stages, and the machine names the one

It grinds, doses, tamps, brews under pressure and steams milk. Each is a stage that wears, and the useful part is that the appliance rarely leaves you guessing which — a message about filling is not the same problem as a shot that runs thin, and treating them the same is how a working machine gets replaced.

### What decides the figure

Which stage, and whether the unit is plumbed. The “from” is a brew unit service or a tank seal on a machine that comes forward in its housing.

What this involves

The published fill routine tried before any part is named

Grind and brew unit separated before either is replaced

A plumbed leak treated as urgent, because the cabinet is

Water and air first

The circuit fill message is air in the line and the maker publishes a routine for it. We try that before anything is opened, and it costs you nothing when it works.

Grind against brew unit

A shot running thin and fast is one or the other. Beans that have changed, burrs that have worn, or seals in the brew unit — and they are told apart rather than both replaced.

The pump and the boiler

Pressure and temperature, measured. This is where scale shows itself as a part rather than a message.

Where the water is

Front, back or underneath are three different repairs. Water at the back of a plumbed unit is the one worth stopping for on the day.
