Gaggia color leaks

You need to identify what's leaking before you can fix it.

Clean the engine well, perhaps even pay for a 'steam clean" there.
Drive home. Use a light and a mirror to examine where the oil is coming from.
Oil leaks can come from oil pan, valve cover, front or rear seal, oil filter not fully tight, more.. .
I finally tracked a stubborn oil leak down in my car when I took it in for oil change. Was the filter that hadn't been fully tightened the last time...

If it is coffee colored water, check the chamber under the white plastic valve behind the brew unit, that might be blocked with coffee grounds. If it is clean water one of the lines might need new o-rings.

What color is the steam manifold? It is located under the black cover with the trough in back under the white tube. If its white or black it probably needs to be replaced. If you cool down the manifold after steaming you can prevent this from happening. Just turn off the steam and then open the knob again to run water. It comes out steam at first but then will turn to a water stream. Then you can close the knob and go about brewing or just let it stand. But its going to have to be replaced.
If it is silver you probably have O-rings that need to be replaced. I would use the black O-rings, not the red. The red ones are a little smaller and can leak.

Sounds like the gaskets need replacing.
A faulty steam solenoid can cause no water from the group head too

I have ordered a new valve and rubber seal-thanks for getting back to me.If this does not do the trick I will buy a new machine.Cheers colin.

The steam valve tap rod needs to be replaced, or check machine if it has a plastic steam valve, Gaggia designed a new Stainless steel steam valve for the compact machine.

you have very steam because like you know our loosing our pressure you need a seal kit be carefull when you play in there calcium buildup is very hard to remove cheers

i had this same problem. the solution is simple if you are a little bit handy.
there is a bad valve inside. i called Whole Latte Love where i bought the machine and ordered a Steam Valve complete - Compact Frame
its part number GA-%0345.R and two O-Rings

the valve that comes with the machine is plastic and the new one is a brushed metal casing. my guess it will last for 10 years!

two screws on the back and the machine is open
near the front, by the steam wand, with a hose attached coming from the heater, is the valve, attached to the knob on the side
two more screws and the valve wrapped in a plastic housing comes out.
open the plastic housing, remove the insulated hose to the steam wand and the water/steam plastic hose that comes in. replace the valve, hook up the two hoses, but back in housing and you're done. attach back to knob on the outside, put back together and in 30 minutes, the Titanium is like new. no leaks.

it sounds daunting but is pretty easy and beats sending the machine back for repair. i can't go a morning let alone a month without coffee from my Gaggia. once repaired, the coffee is hotter too.
