I have a commercial wega double espresso and double frother. The frother works! you can see the fill line filled with water, but the espresso maker is not shooting water, you can hear it work when you...

This issue can happen if the site inlet water pressure falls below 1 bar. The boiler fills but as you draw drinks it won't refill.
Do you service the machine ever and replace the water filter? Limescale build up may be another reason you are experiencing problems.

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. Thanks Mike

Miniwx epu no water coming from group head to cup no water at cylinoid

Since there is no water at the solenoid, then the blockage must be at the metering jet, which sits under the nut on top of the group, turn of water supply and be careful when removing nut do not damaged o-ring if it is not a teflon O-ring, you might have a leak. Clean out jet and filter then reassemble.

It does not fill with water

Check the nut on the top of the grouphead, make sure water is off and machine has cooled down, carefully remove nut, try not to damage gasket on the bottom of nut, check the screen and jet.

I have a wega evd1 atlas; and there seems to be some sort of problem with the water not heating up at all. The steam wand is just shooting out water and the water is just coming out at normal temperature....

Hi The first thing I would check is a reset button on the boiler. The next thing would be to do a continuity check or Ohms check on the heating element. If you get no reading you have a bad element.

No steam coming out of heating nozzle for Wega

Remove the nozzle on the end of the steam wand, them open valve to see if the steam wand works, if yes use a paper clip to clear holes on nozzle, if no remove steam wand where it is connected to the valve then open wand(steam will be spraying be careful). If you have steam there then clean wand and nozzle.
