The pump on my 1999 classic just stopped working between coffees yesterday. I brewed one coffee fine, and when I tried doing a second, the pump wouldn’t start. It still makes a click sound when the pump switch is pressed, so the solenoid still works. There’s definitely power to the machine because the pid lights up. So I have a couple questions.
Firstly, is there anything I missed in my diagnosis? Maybe there’s something obvious to look for when opening the machine…
Secondly, if the pump is broken, is it simple to replace with something like the one in the link? My particular model is quite old, so maybe they don’t make compatible pumps anymore
You got a dead pump. But lucky for you, parts are cheap and it’s pretty easy to work in these things. Search YouTube for Gaggia classic refurbishing or get more specific, there’s a ton of videos.
I’ve bought a few old classics and fixed them up for myself and friends. They’re pretty simple, you might want to take the opportunity to replace the boiler gasket and descale it while you have it open. If you’ve never done this before and it’s that old, you might be surprised how gross it is inside. You can buy a kit to refurbish them that comes with all the gaskets you need. I would also highly recommend preemptively replacing the thermostat. It just screws in to the boiler. I’ve had one short out and catch fire in a old one, now I replace them as part of the refurbish.
