# Wolf coffee system leaking water

### The fastest diagnosis is the code

Empty the drip tray and dry the shelf, then make one drink and watch where the water appears. Front, back or underneath are three different repairs, and knowing which halves the visit.

### Where it appears is most of the diagnosis

Water at the front, during or just after a drink, is the tray, the tank or a seal near it. Water at the back, whether or not anybody has made coffee, is the supply. Water underneath with a thin shot is the brew unit. Watching one cycle with the shelf dry tells us which of those three we are coming for.

The drip tray, simply full

The commonest reason by a wide margin, and it costs nothing. A tray that overflows looks exactly like a leak.

The tank or its seal

A tank seated on a crumb, or a seal that has hardened. Water appears at the front and only when it is full.

The brew unit seals

Water inside the machine rather than in the tray, usually with a shot that has also gone thin.

The plumbed connection

On a plumbed unit, the supply line behind the cabinet. This is the one that damages a kitchen rather than a machine.

Scale in the drain path

Water that should have gone to the tray finding another way out.

Empty the tray first

Then look again. It settles a surprising share of these calls.

Watch one drink

Note when the water appears — during the grind, the brew or the steam.

Front or back

Front is usually the tank or the tray. Back is the supply, and that is the urgent one.

Shut the supply if it is plumbed

There is a valve behind or under the cabinet. Turning it off costs nothing and stops the damage.

Worth reporting quickly in joinery

What it usually means

Water at the front, under the drip tray

Damp at the back of the cabinet

A puddle after every drink
