Hi, first post here and can't find anything similar to the problem I have - any help appreciated.
I have an old Gaggia Coffee machine (about 18yrs old). It's been maintained well, descaled reasonably regularly, etc. A few replacement parts (gasket, brew head, etc). It's worked so well for 18 years, I'm loath to buy a new machine which will be less repairable.
A few days ago water stopped coming through the brew head. Steamer still works. I've checked for airblocks using usual methods and can't find any problems. So I did a full teardown of the machine (boiler and group head) and gave it a full clean and check. Back together and same issue persists.
I turned the machine on, left to heat up for a minute, then switched on the coffee switch. Pump *sounds* like it's working properly, but still no water making it out of the brew head. If I take the brew head off and remove the spring/rubber valve mechanism from middle of the group head then hot water flows through (about 100ml in 10s) when I switch the coffee switch. Put the spring/valve back in and, again, no water comes through.
Could it be a faulty pump? I think the flow rate without the valve in seems OK, but maybe there needs to be more pressure to push the valve open (these 'Coffee" machines don't have a solenoid/switch). Everything is definitely clean and free of any major scale.
Any help would be much appreciated to try and resurrect the beloved machine!
