Becouse the boiler is aluminium and oxidates with time even you relese 2 screws of valve again valve dont move easy off. you need to put screwdriver between valve body and old boiler, might be needed 1 ce or 2 ce to hammer the screwdriver after that it will come out.

PS before starting replacing valve release the copper pipe that goes out from valve.

Replace the thermal protector on a Saeco Espresso machine.

This expresso machine is a double boiler unit and the thermal fuse is located in the steamer boiler (boiler closest to the top of the unit). The fuse is actually wedged into the steam boiler. Make sure the unit is unplugged. Remove the water reservoir then remove the 4 screws that hold the reservoir housing in place (you will need a torx wrench for 2 of the screws). Next remove the warming lid on the top of the unit by lifting it from the back. Remove the 4 screws that hold the metal upper cover in place. You may need to remove the 2 screws that hold the front panel in place to have enough room to loosen the thermal fuse fixing plate. Unplug the wires that plug into steamer knob control unit. Remove the protective cover to the steam boiler. Loosen the screw to the thermal fuse fixing plate. Remove the thermal fuse and replace with new fuse. Do not solder in the new fuse otherwise you may cause the fuse to fail due to the heat of soldering. The original fuse is a 233 Celcius and 15A. I purchased a thermal fuse from radio shack that is rated at 228 Celcius and 10A ( So far it works fine. You can also purchase thermal fuses from For a schematic go to SIN 025RX explodeddiagram.pdf.

Water dripping not running when making coffee

First question:Are the rest of the machine still working correctly?
Second question:How was the waterflow before descalling?

Here are short description on how most of these machines work.

It will have a cold water reservoir for filling with cold water with some sort of water full sensor, it will then be followed with a high pressure pump.which are used to fill the boiler.After the boiler it will then go out to your to your case the steamer and one for coffee.The outlet at the boiler will propably be split in two by using valves.

To come back to your problem i assume it had a waterflow probleme before you descalled.When you are descaling your machine their are some times pieces of scale that is not propably disolved by the descaling process which will get stuck in the pipe work acting as a valve
causing waterflow problemes.

The other probleme might be that your water dispencers valve might be faulty either by a poor supply(power) or the sollenoid is starting to size up.

Just switch of the machine when taking of any covers you are working with water and electricity which do not mix well

No pressure in machine. i can't get any decent water stream from coffee outlet; only rare drops. steamer works fine. Can you help me?

Their are four posible reasons for above problem as follows.
First the Vibarating pump not creating pressure, usaly if here the sound it is pressing but not always. You can loose the pipe nut after the pump to see if you have any pressure after you press the coffee button. Be carefull with the water leaking.
Second the coffee solenoid valve that is on the grouphead might be stuck from dry coffee, it can be removed and cleaned with hot water and a wire brush.
Third the coffee group shower and inside round dish might also blocked from dry coffee, remove it and clean it.
Finnaly the more difficult problem might be that boiler-thermoblock is full off scale. So you must remove and descale the thermoblock boiler and the copper pipes to them.
This problem is the more difficult to be performed however if the water you have use was very hard then this is the most posible.
Good luck,

Burnt smell is coming from steamer wand

Boiler is contaminated with milk, check the water from the tea valve, if it smells the same or has swimmers, boiler needs to be descaled, if no floaties then removes steam wand and soak in purocaff for a few hours, then clean. Always flush ssteam wand before and after every drink.

Baby gaggia steamer doesn't work

Does the machine brew hot coffee? If yes, then remove the parnello and clean the holes at the end of the steam wand. If that does not solve problem, then it is blocked where valve is connected to boiler, Try descaling machine. If no then the thermostat on the boiler has tripped and needs to be reset.

I bought a coffee machine feama e98 but it was leaking pure water while active.Please help me,show me repair that problem.Thank you very much!

From the top: it is possible that the vent valve needs to be replaced, that would be the small cylindrical fitting with a brass pin in the middle of it. This valve is centered in the middle of the boiler or on top of the sight glass.
From group heads: the brew solenoids need to be replaced, they are the blue or black electronic boxes with the square base sitting on the side of the group heads.
From the drain tray there is supposed to be a slight drip from the expansion valve which will be located in the middle of the machine, if the front panel is removed there will be 3 pipe fittings directly above the tray 2 will lead to the solenoids on the group and the middle one which will be totally different is the expansion valve. it should produce a tiny drip no more than once a second.
From the steam wands: remove the bottom nozzle and check to see if the holes are clear, if not use a paper clip to clean, then open valves without nozzles and check if the pressure is the same, if not then it is being blocked at the boiler fitting or along the pipe connected to the valve from the boiler.
