Free the top by unscrewing the 2 screws in the front shiny cupwarmer section and the 2 screws in the plastic part in the back.
-
Carefully take off the top to reveal the inside of the Gaggia.
-
Be sure to unplug the power cord before working on your Old White Coffee Gaggia!!

Here you see the water intake hose, sucking water from out of the water tank and delivering it to the water pump.
-
The hose connects to the pump at its bottom side, so you can't quite see it.
-
The hose is secured to a black plastic piece in the bottom of the case by a metal clip that can be loosened with pliers.
-
Take off the hose and be careful not to lose the metal clip!
-
You can't take off both endings yet as the end that goes into the pump is still hidden!

Very dirty but functional, this is where the power cable is connected to all the wires we just freed.
-
You will only need to take out the cables on the right (bottom side on the picture), starting with the 3 from the power cable. (ground, brown and blue)
-
Unscrewing the whole luster terminal can make your life easier here.
-
-
-
Unscrew the nut securing the steam valve assembly to the top of the boiler.
-
You can just pull the steam assembly out of the way for now.
-
If you have the fitting Allen key, you can also take out the steam assembly by taking off the black knob and pulling the assembly out to the back.
-
-
-
The vibratory water pump sits on a rubber fitting.
-
Unscrew both screws to free the pump.
-
Take out the whole pump/fitting assemby.
-
Unfortunately, the black rubber thing on the bottom of the pump originally connecting to the high pressure teflon hose is broken, be careful with this piece as there may not be a replacement!

Let's have a look at the portafilter holder and the screen at the front of your machine. As you can see, mine has its share of rust and gross dirt.
-
Unscrew the single screw in the middle of the screen.
-
The screen might be held in place by dirt and coffee of decades past.
-
-
-
Ewwwww...
-
I managed to take the screen off by jiggling a little on it with a screwdriver.
-
There are 4 screws holding the outer ring in place, unscrew those and the outer ring should come free.
-
-
-
Return to the inside of the machine and unscrew the 4 screws at the top of the boiler. Be careful not to strip the screws!! Gently pull the top of the boiler off.
-
Prepare to be grossed out.
-
Somewhere below the white/brownish stuff in the 3rd picture there is a black gasket hiding. Can you find it?
-
This is very similar to, if not a gaggia classic. Even a machine at such a state can be 100% repaired
