Bad pressurestat or bad heating element. PS feeds power to heating element, heating the machine til its up to pressure, which then turns the pressure stat off. If either of the two pieces are bad neither will work properly.

Could also be the machine is overfilled which causes the machine to take longer to heat up.

With the machine cold (or hot if you have the right implement and can keep your hands away from the steam) I would try to insert something like a pin or a small length of bicycle brake cable up the frother tube and see if you can free what probably is a plug of solid mik in the end of the frother. Sounds like a blockage, it may suddenly blast out steam if you free it and you have the valve open so watch out. If it's not that then I would take the valve apart, especially if the machine is making the right noises. I'm not farmiliar with AEG machines though.

SOURCE: Steam wand works, but no water for espresso

I have found that I have to remove the group valve assembly about once every 1 or 2 months to clean out the .030" to .040" opening in the valve body. The manual gives instructions on how to do this. It becomes clogged with a thick paste like substance.

I have had similar issues with my 40729.
Assuming that when you turn on the steam switch, the steam light goes on and then off when up to temp:
I have resolved this by filling my steaming pitcher with boiling water, remove the end-cap from the frothing wand and soak the end of the steam pipe in the hot water for several minutes. Then fire up the steam and blow it out. if the obstruction is more serious, then you may need to unplug the machine and run a thin and stiff wire ( like a guitar string ) up through the wand to break up the clog.

This unit uses one heater for both the extraction and the steam, so if you are getting extraction then the heater is good. You may also have either:

  • a bad needle valve in the steam knob on the right.
  • a bad thermostat that regulates the heater temp when you turn on the steam switch.

DPcurry is right. You may have to plug it in to get a "feel" for which way and to what degree to rotate the shaft, but works like a charm.

Ranchilio Silvia steam not working..
If you're experiencing issues with the steam function on your Rancilio Silvia espresso machine, such as low steam pressure or no steam at all, there are a few possible causes and troubleshooting steps you can take to address the problem:
  1. Check Water Level: Make sure the water reservoir is filled with water to an appropriate level. The steam function requires sufficient water to generate steam.
  2. Purge Air from Boiler: If you're getting low air with no pressure from the steam wand, it's possible that there's air trapped in the boiler. You can try "purging" the air by turning on the steam wand and letting water flow through it until a steady stream of water comes out. This might help remove air pockets from the system.
  3. Steam Wand Blockage: The steam wand could be partially blocked by milk residue or mineral deposits. Clean the steam wand thoroughly using a steam wand brush and ensure that the tip is clear.
  4. Vent Valve: The vent valve on the top of the steam wand might be clogged. Try removing the valve and cleaning it to ensure proper steam flow.
  5. Boiler Pressure: Low steam pressure could be a result of inadequate boiler pressure. Check the pressure gauge on the machine to ensure that the boiler pressure is within the recommended range. If the pressure is too low, you might need to adjust the pressure settings (if your machine allows for it) or seek professional assistance.
  6. Steam Valve: The steam valve might be worn or malfunctioning, preventing proper steam flow. If the steam valve is not functioning as it should, it might need to be repaired or replaced.
  7. Boiler Heating Element: If the heating element in the boiler is not functioning correctly, it could lead to low steam pressure. Check for any signs of damage or malfunction in the heating element.
  8. Professional Service: If none of the above steps resolve the issue, it might be best to seek the assistance of a professional espresso machine technician. They can diagnose the problem accurately and perform any necessary repairs.
Remember that working on espresso machines involves potentially hazardous components and high-pressure systems. If you're not comfortable with any of the steps or if the issue seems complex, seeking professional assistance is recommended to ensure your safety and prevent further damage to the machine.

Increase steam flow
If the steam is slow to recover the most likely issue is scale build up on the water level probe on the boiler. Scale builds on the probe and the boiler over fills leaving less room for steam to build.
the probe is usually easy to remove and clean but this MUST BE DONE WITH THE MACHINE COLD AND ALL STEAM LET OUT.
If you are unsure take the machine to an approbed repair centre to avoid risk of scalding.

Wega espresso
Steam out of the top is a bad safety valve.

Steam out of wands when they're off is bad gaskets in the valves which usually means they need to be rebuilt.

Steam out of groups is a water blockage and/or pressure stat is going bad and causing the machine to over heat.


Can be any one of the following. Need more information to answer properly.

We have an old Wega model EPU1(grey/burgandy) it is not frothing too well. It is as if there is water diluting the milk and the froth contains very large air bubbles, any ideas on what we we need to do...
i believe, if i am understanding this, as i guess here, when you are frothing the milk, it seems to also fill up faster, like water is not steaming as much as it is filling. As you know, steam is hot water turned into steam, now what is happening the steam is half steam and half water. If this is the symptoms along with air bubble, then it points to O RING replacement, direct water is getting through before it has time to steam, on a commercial type machine, you are better off to have a mobile espresso guy come out in your area, replace the o ring in the wand, and also make sure no other damage has been cause from back water pressure on electronics. I hope this helps, this is a do it yourself job, but would not recommend if you really don't know about guts of the machine and electronics. The computer is the major expense of the machine.

Zero steam from steam wands. No pressure.
First thngs first, make sure knob is turned to 2, then make sure there is water in the boiler, then turn machine to 0, remove back panel and reset thermostat on top of back boiler, if your machine has that feature installed. Then turn machine to 2, open one of the steam wands, If within 10 minutes boiler does get hot or there is no water bubbles, from steam wand, then the pressure stat might be damaged and needs to be replaced.

My shaerer expresso machine (ambiente) is giving error, level steam probe, when this happens it will not steam. This problem does not happen all the time and can be cleared by shuting machine off then...
"level steam probe" occurs when it takes more than two minutes to fill the water in the steam boiler. The easiest solution is low water pressure to the machine. Does it have a water filter? replacing it will probably help. Other problems could be the fill valve is not opening fully and or scaled water lines going to the steam boiler. The first thing I would do is activate the hot water tap and look at the pressure. If the water is coming out slow then I know its a restriction to the machine.

Espresso machine not steaming
If the machine heats up for coffee, then the steam wand tips are probably blocked. Use a paper clip or needle to clear out the holes at the end of the steam wand.

Espresso machine loses steam than recovers in minutes
It sounds like a heating element issue. Those elements look like a single unit but are actually made up of 2 or 3 independent heating coils - one may not be working. So, you're only getting 1/2 to 2/3 heating capacity, which isn't noticeable until the machine is under heavy steam load.
