Everything turns on, and the steamer works. However no water comes through to the cup; it doesn't percolate coffee.

Re: Gaggia espresso machine won't percolate

Does the steam outlet give water when coffee swith is engaged. If so when you get a flow going, shut the steam valve and water should eventually pout in the cup. If no water pours thru the steam pipe, it's pump failure or blocked wand. If no water at shower depending on last result same problems. Search web for solution i.e. google "jammed espresso machine"

Gaggia Evolution Filtering Weak Coffee

Basing on personal experience (you can find more on Google probably), solutions are:

On percolated (filter) coffee machines:

Check water temp, if water temp is insufficient , most common is scale heating element , faulty element, faulty thermostat.
Check if water is dripping right at the center of the filter, if it is dripping on one side because the orifice is clogged, that can result in weak coffee.
Coffee blend not well distributed on filter basket.

On Espresso machines:

Check water temp, same as filter coffee machines (thermostat element, scale on heating chamber).
Ensure that coffee is filled correctly in the filter cup (fill at level), and well pressed.
Ensure that the coffee mixture that you are using is not too coarse, buy the apposite one for espresso.
Ensure that you are not leaving the machine brewing for a time that is too long, and Italian coffee cup is very small, approximately one regular shot.

On the hob moka pots (espresso, Moka and Bialetti type):

This are the trickiest ones, you need art and practice to get a good espresso with a Moka, but when you learn, the result is better than what you may get with an home electrical espresso maker.
The frame on the hob must be not too strong, and the mixture coarse but well pressed, with water at level tag, or you will get a weak coffee.
On Mokas a good strategy is keeping hob at minimum, and turning up the flame at top when coffee starts coming out.

French and turkish cafetieres:

Ensure that you put enough coffee, water hot enough, and that you left the infusion enough time to get a strong coffee.

Note: insufficient pressure and clogged lines on electric machines never give you a weak coffee, exactly the opposite.
Not pressed mixture always gives weak coffee, but too much pressed mixture may give you coffee with bad taste.

Steamer on gaggia titanium

a. Possible air in the system. Switch to hot water iso steam, let warm water pas for a minute by turning the knob fully open. Stop tapping warm water (close the knob) and switch the machine to steam iso water. Try to get the steam by fully opening the knob (pump should start running). 
b. Solidified milk in the system blocking internal tubes. To avoid this always purge the system (shortly open the steam to an empty cup or a towel) after you steamed milk to avoid milk being sucked back into the system due to condensation of steam (this creates a vacuum and reverse flow). To resolve the blocked tubing: clean the nozzle and try flushing the system (tapping warm water).

You need a bellows pump or similar, when you start the pump you need to set the pump to the water inlet and press in the water with force.
