Symptom Diagnoser

Tell us what your machine is doing. You get the causes ranked by how often they are actually the problem — cheapest checks first — plus the guide and the part if you need one.

  1. 1 Brand
  2. 2 Model
  3. 3 Symptom

Model not listed? The list only shows machines we have actually worked on — we would rather say nothing than guess. Tell us which one you have.

Or start from the machine

Before you open anything Unplug the machine and let it cool completely — boilers hold scalding water and pressure for 30+ minutes after shutdown. Opening the housing usually voids any remaining warranty.

How the ranking works

Causes are ordered by how often they turn out to be the actual fault on the bench — not alphabetically, and not by how expensive the part is. The first one or two on any list are almost always free to check.

That ordering matters more than it sounds. The single most common way people waste money on a coffee machine is buying a pump because the machine will not push water, when the actual fault was a blocked tank valve costing nothing to clear.
