Use a flat head and pry it off the machine. Sometimes running some descaler will help loosen it up.

Gaggia Classic: how to replace the steam valve

WholeLatteLove has the necessary parts; they are the valve and an O-Ring or gasket. The valve is held in place by two Allen head metric cap screws. You remove the knob, open the case, remove the steam wand tubing (you reuse this), take out the cap screws and the valve comes off. Just reverse for assembly, don't overtighten the cap screws as they thread into aluminum. I've replaced several of these over the years; they don't hold up well. I have one to replace currently, and plan on using the old valve body as an adapter for a commercially available needle valve that hopefully hilds up better and is easier to get and costs less. IIRC, price on the Gaggia part is about $35. Hope this helps.

Gaggia Classic (3 months old). Suddenly there is steam only, no water flow.

If there is no water from the head then remove the screw and screen, then press brew button, if water flows clean shower, using a pair of plies hold screen over open flame, coffee will burn out of the small holes. If no water after trying above then remove the 2 allen wrench screws and carefully remove the diffuser and seat with spring, now try running the head, if water flows reassemble and you are back in busines, if no water descale machine.

I want to change the head gasket but cannot remove it.

Remove the water tank and drip tray. Then turn the machine upside down. That way you can see the gasket. Stick you allen wrench into the hole the screws were in and pry the center out. Now you can get a screw driver under the gasket and pry it out. It might come out in pieces but that is OK. They get hard and that is why they won't seal. They should be replaced once a year to work good.

My precious Gaggia Classic machine has developed a "fatal error". It will not pass water through the shower head. I have tried cleaning, re-priming to clear air block, several times over. The pump appears...

Remove the shower, then the 2 allen wrench screws for the diffuser, careful do not loose the spring ad valve seat that is above the diffuser, now turn machine on to see if water will come thru, if water flows, problem is either screen or diffuser blockage, if no water then you need a stronger descaler because blockage is in the boiler, at the solenoid or from the pump. Most likely in the boiler, if you have a boiler gasket go ahead and open the boiler to clear the blockage.

Hi, My Gaggia Classic is not working. No water

try to clean the group shower which it can be ansrew by one cetrer screw and if you can you can open the machine and remove to clean also the coffee group solenoid valve. Bothe the valve and shower can be full of dry coffee that can blocked the way of water coming to the grounded coffee.
If you manage to clean everything above and the machine work ok so from now on in order to avoid the problem again try to flush water from the group many times without any coffee. With this is like you wash the group shower and valve from any remai coffee.
Good luck
