Of recently I have come across an unusual problem where by Expresso Machine won't produce steam. When I turn the knob to the right the Expresso Function will work but soon after I turn the knob to the left for the Steam Function the Machine will not operate where by it doesn't make that thumping noise before the Machine will produce steam through the valve.
Any ideas? I had only de-limed it in the last month or so.
HI Folks, I had the same problem and I have found a solution that worked for me. I took a look at the circuit board (I am an electrical engineer) and I could see an ever so slight buildup on the circuits behind the chips. It looked like some water or steam dripped back there. Then with some effort I was able to peel the circuit board off the glue and wash the back of the board where the solder is with clean water and a gentle brush (all circuit boards are actuall washed after they are made) then I dried it by placing it in the sun. After and hour, I put the board back in and presto the "thumping" and steam were back !. I hope that helps.

I contacted Breville and they were very gracious about a return. They took mine even though it was a couple months beyond the warranty and replaced with a new machine. The new machine has some new changes that seem to help prevent the frothing arm from clogging so easily. I do like the improvments.
I too am having a similar problem with my breville espresso machine. Whereby i used to be able to froth the milk with no problems but these past couple of days, the steam button light is illuminated, when i turn the knob to steam the milk, the steam button's light goes off and the hot water gets illumintaed and all i get is hot water. It also does not make that thumping noise it usually does just before the steaming begins. Please help!
I have tried clenaing it, letting the hot water run for a few minutes (not just seconds) but still the issue isn't resolved. I am thinking about taking it back to the manufacturer as it is still under warranty. Only prob is they are on the other side of the state :o(

The steam function and the expresso use the same elements to create the steam but the valves will direct the steam to the expresso unit or the steam arm. Most likely you have a faulty valve. In most cases the valve will not open until the pressure gets to the right level. If you are just getting hot water out of the steam arm instead of steam via the expresso unit it most likely means that the valve is faulty. The valves can be replaced but is not easy. You will need to have the unit serviced or you could try to replace the valves. Make sure the flow meter is working before you replace the valves. You can check the operation of the flow meter by running the hot water cycle and making sure that you get the right amount of hot water. Good luck!
Hi, I dont know which brand machine you have, but I should be able to work out what is wrong. If your machine has a press button or turn knob steam tap, then it could be the solenoid which opens the steam flow. The solenoid itself maybe stuck or the coil maybe faulty. You just need to work back from the steam arm to work out which solenoid it is. It should make a clicking sound when activated. Commercial machine solenoids canbe disassembled and cleaned. If its a domestic machine, then just replace the solenoid. Also, some machines have a micro switch that activates the steam valve. If its faulty, then replace it. If its a domestic machine you have, then another thing that maybe at fault, and that is the thermoblock (small boiler). If it doesn't heat up then no steam canbe made. The thermoblock has an element inside, and they can not be replaced. You have to replace the whole thermoblock. It can be easily checked with a multi meter to see if the circuit is broken. On some thermoblocks, is a thermostat or overload sensor. It is also easily checked with a meter. So lets break it down a) solenid b) micro switch c) Thermoblock d) thermostat/ thermol overload Hope this has help you. Id be looking towards the thermoblock. Dazza
Your machine need to reach boiling point to produce stem? Then check if all the sustem is sealed other than the pip outlet gun and it should now operate with the gun trigger ( pull to operate, but only when the water within the vessel is boiling, producing steam)Hope this helps Regards Mike
Your are propably need to prime the machine. This mean that air blocked in the machine and need to get out and fill all pipe system with water.
To do this you need to warm up the machine and turn the hot water knob so you will get one cup of hot water from the steam wand. After that try to get some water from the coffee head without any coffee in the filter handle. Now the machine is ready for coffee again. You will need to prime the machine very often so try to remember the procedure. This will happen again usually after you use the steam process and this normal for your machine. http://www.fixya.com/support/r5772014-saeco_gaggia_spidem_ventilate_prime
The machine have a separate heating system for steam than hot water for steam. The steam system it might be full of scale. If you hand are good you can easily remove top panel and side panel. You can follow the teflon pipe from the steam wand and it will lead you to the steam solenoid valve and the small copper steam heating system and desasemble it both the valve and small boiler and remove any scale and dirt from it using a wire brush, shurp screwdriver and similar tool. Then poot them back together. You can try the machine with panel removed so if it needs something more to try once more again. One small tip advice. Use your camera and make pictures of everything before desasemble them, then you are safe if you forget about something. In this way you can clean everything metalic that the water pass though.
The thermal fuse in my Starbucks Sirena Expresso Machine failed. You will know if it has failed if you unit doesn't turn on and/or your unit doesn't produce steam. 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 (http://www.radioshack.com/product/index.jsp?productId=2102788). So far it works fine. You can also purchase thermal fuses from http://www.goodmans.net/get_list_632_2.htm. For a schematic go to http://www.saecoparts.com/user/Sirena SIN 025RX explodeddiagram.pdf.
Hi Unplug the machine! First remove the steam knob. hole below the steam knob. Straight blade screw driver. loosen the screw about 2 turns and the steam knob will unscrew. next remove the 2 screws on the front. Next remove the 4 screws on the under sides of the machine. The top will slide back and off.
