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
Swapping out the pump should be relatively straightforward. One thing you might consider when buying a new pump is getting the brass version (Ulka EX5) that many have said reduces noise. There’s also a higher wattage version (52W instead of 41W) of the same pump that has higher water debit and can give you more flexibility which is the one I got for my machine (Ulka EAX5)
