Gaggia Coffee Parts List

The shell of my Gaggia Coffee looks like the current Classic Coffee but the internal components look like those in the Gaggia Coffee Deluxe or Coffee 97.

It looks like the model numbers for the Coffee 97 are in the the 37000 range while the Coffee Deluxe is in the 97000 range

The Coffee Classic model numbers start in the 14100 range.

I have found good source of information about both of these machines at Parts Guru.

I hope to find the correct manuals and parts diagrams in the near future but until that time I will use the Parts Guru information as well as other Internet resources to help guide may way.

Classic Coffee Information

Coffee Deluxe / Coffee 97 Information

Figuring out the parts I need for a restoration is a challenge. So far I think I need:

DM 0041/088 - OR2025 Gasket - O-Ring for steam wand
DM 0041/022 - OR2018 Gasket - O-Ring for inlet fitting and group valve assembly
DM 0041/031 - OR2018 Gasket - O-Ring for suction pipe

Gaggia Tear Down

Nice looking crack on the portafilter. I should have caught this in the ebay photos but I didn't. One good twist to get the portafilter sung would have snapped the handle right off.




It appears the pump was leaking at some point in time. During my tests I did not notice any leaking around this area. The stains underneath the pump in the housing also support it was leaking at some point.



The inside of the housing is covered in some tan substance that does not want to come off easily. I hope it will come off with some 409 and hot water. I also noticed some black particles in the corners that may indicate the Coffee was home to some small critter. 



Note the increased staining in the pump area to the top right. I could not find any rust on the housing and the paint is sound.





It could be much much worse based on pictures I have seen on the Internet of other owners boilers after a tear down. I think descaling before disassembly helped. I will still clean it up with a Dremel tool.




It is interesting to see how the chrome is missing in certain areas of the group head. The boiler gasket was totally dried out. Pieces of the gasket were starting to fall off when I removed it. It is no wonder the boiler was leaking in this area.
