📹 Gaggia Classic Pro: Flow Check, Pump Check and Pump Replacement

Learn how to resolve flow issues with the Gaggia Classic Pro, including how to check for flow, check the pump, and how to replace the pump.

If you've already checked and cleaned your solenoid valve, and sent forced air through it, and your machine is still not producing brew flow, you can actually check the pump itself. If you find that the pump is faulty, you can replace the pump.

Before checking the pump, though, make sure that your intake tube is clear, and that it's not kinked or pinched behind the reservoir. Be sure to take a look at the "Gaggia Classic Pro Parts Diagram" and use it as a point of reference.

1. Remove your reservoir

2. Check the intake tube. It's the longer of the two tubes going into your reservoir. It's location has been circled in the image below.

  • Make sure that tube is in the reservoir, and NOT wedged between the reservoir and the machine housing. Also, make sure there's no gunk in the intake line.
  • If that's clear, you can check the pump. To check the pump, in isolation, remove your machine's lid, and locate the tube leaving the pump. This has been marked with arrows in the image below.

  1. There's a knurled nut (#32) that holds the tube onto the boiler intake. Unscrew this nut, and dangle the tube into a mug.
  2. Turn on the machine
  3. Hit the brew button.
    • If no water (or just a dribble) is expelled into the mug, then your pump is faulty, and needs to be replaced. If that's the case, the follow the steps in the video below.
