Low pressure. Could this be the problem?

Recommended Posts

Hi,

 

I have taken apart my Gaggia Classic and I see that water is only coming out of one of the holes in the picture below. Is this normal? If not, what is the best way to unblock these? IMG_1543.jpg

 

Thanks

Looks like the shower screen holder bolts are removed. You should be able to pry the aluminium lump off the head and give it all a good clean underneath. It probably glued on with the coffee oils!

take as much off the grouphead as you feel comfortable and soak in a bucket of descaling solution (cafiza) and also look to replace the rubber seal around the grouphead as im assuming that isnt in good nick either!

It is acting if it is welded on. Are you sure this should be able to come off?

Yes, thats the dispersion plate.

The center hole is the shower screen retaining screw hole, the two bolts you then removed hold the dispersion plate in place.

See images of it here

Yeah, most definitely comes off! Considering the symptoms it is no surprise that it is stuck on! There was a thread in the gaggia section recently regarding removal, but can't find it at the moment.

 

Edit: still cant find it! Generally the easy option is to take the shower screen screw into a hardware shop and buy an inch long version with the same thread. Screw that into the central hole until it meets resistance (indicating the screw hitting the boiler body) and then continue to apply gentle, regular torque to try to pop the aluminium puck off the boiler base. Sometimes heating it up will help, others have recommend a good tap to the bolt to jar it off the boiler. I personally use a wood screw into the portafilter seal, screwed in until you just feel an increase in resistance to turning (indicating it is about to go all the way through the seal). Then grab some pliers and lever the gasket off, and by default the shower screen holder too. Care must be taken as if you screw it too far you may mark the surface under the seal. Depends on how confident and delicate you are, or if you are near a hardware store to buy the bolt :)

Another method can be a broad, flat bladed screwdriver levering it off from the side. Expect the screwdriver to slip and mark the aluminium. Not recommended unless you are happy with damage or are annoyed enough to not care. I mention this as an option just to complete all the methods I've tried with success. the lever can be used in conjunction with the bolt to provide extra force.

But that puck looks in nice condition and would be a shame to scrape it... Use the bolt method!
