I own a Expobar Leva and I can't get decent microfoam. I have watch a lot of videos, frothing soap water for at least two hours with some sucess. I have notice that there is some water spitting out from the steam wand, but only with tip unscrewed. Drawing hot water from the tap reduces the volume of water spiting out but the autofill kicks in just after I get pure steam. After the boiler is filled I get water spitting out again. What should I do?

Sounds like the water level in the boiler is too high. A common cause is scale build-up on the auto fill probe.

It is one month old and with water softener...

Another common cause is misadjustment from the factory (in general on espresso machines, I'm not calling expobar as a company known for this). You should be able to adjust the autofill level probe to set the maximum boiler level to meet your tastes. It's the plumbing fitting on the top of the boiler with a wire that goes to it, likely with a white plastic collar and a probe in the middle. With the machine cold, loosen the inner nut and carefully slide te probe down a small amount. Be careful not to overtighten the plastic bits.

Probably not scale then, no. Maybe the probe is in the wrong position then? Still sounds like the water level is too high, I think. At least I can't think of anything else that would cause water to come out of the steam wand.

Has it always been like this?

I recently discovered it because I am curious enough to open the valve with the steam tip off. With the steam tip on I don't see any water spitting out, just very wet steam, like those on thermoblock.

Sometimes the steam tube will condense a little water while idle. When the steaming wand is first opened, the steam may be wet, and you may get some water, but if you run it a short while, it dries out. Is that the case here?

Nope, I get tons of water spitting out after idling for a while. The strange thing is, as I mentioned, there is water spitting out only when releasing the steam without the tip. With the tip, I get no water but a very wet steam.

SOLUTION: Do not steam with the tip off... When steaming milk, leave the tip on...

With the tip off there is less back pressure and the steam will flow more freely and in greater volume than the engineers designed it to do. This has the potential to bring more moisture with it from the boiler and I would assume that some of the steam condenses more rapidly, so I would only be surprised if you said that there is less moisture exhibited with the tip off.

Sounds reasonable, but my problem has sudden gone...
