No water, and the pump rattles
Load the circuit through the wand
The pump runs with a dry rattle and no water comes from the group or the wand. It happens on a new machine, after a long rest, after the tank ran dry, or after steaming for more than 60 seconds. The manual blames an air bubble and gives this cure.
- Check there is water in the tank and both silicone tubes are in it.
- Put a cup under the steam wand and open the knob anticlockwise.
- Press the brew button. After a few seconds water comes out of the wand.
- Run about a cup of water, close the knob and press the brew button again.
- If water is left in the wand, let steam out for a few seconds to clear it.
Force-prime the pump
If the manual's method does not bring water, the retailer Whole Latte Love pushes water into the pump by hand. It is not in Gaggia's manual.
- Switch the on/off button off, and press the brew and steam buttons down.
- Open the steam knob fully.
- Push water into the intake tube with a rubber bulb, a turkey baster or a squeezed bottle. It is the longer tube, with the angled cuts.
- Switch the power on while you push. When the pump's note changes, switch off.
- Refit the tank with both tubes down in the water.
- Switch on and let the wand run until solid water flows. Close the knob, then check the group.
A steady hum with no flow anywhere, which priming does not cure, is a failed pump: see the pump.
