I replaced the pump and it's working, however, when I turned on the machine and the boiler came up, there's a stream of pressured steam coming out of releasing through the top of the machine. Any id


Hopefully, your pressure gauge is working, and if it is at 1.2 bar or so, then you have a failed anti-suction valve or boiler safety valve.
The ASV is the smaller fitting; it might be stuck, so you could try tapping the little button. The boiler safety valve is another matter - it will open at some point past 1.8 bar, which means the pressurestat is shot or its adjustment has been tampered with.

It's most likely the ASV - they do get stuck open as well as closed...

No steam pressure


Leave the valve open until it starts slowly hissing, then shut off valve and wait for the pressure to build up.

Espresso machine HISSING!


It sounds like you have the cup warmer turned on. But if that's not it there is a leak in a connection coming from the bolier. If you open it up it will be obvious where it's at. Don't wait too long because the moisture will effect the electronics.

I had a similar problem. I took the guages out and found the hands were loose on the dials. I fixed them on at gthe low point when the machine was cold and they worked well after that point.

La Marzocco espresso machine troubleshooting


Where is the steam coming from the small valve on the top or the big tall one? If it is the tall one then the problem is in the block electrical box(pressure stat) on the left above the element, that may be stuck and not telling the machine that it has enough pressure turn off the elements.

Old 1996 nuova simonelli mac digit no pressure or heat


There is a reset thermostat on the right side of the machine above the element, check to see if it tripped. If it did make sure there is enough water in the machine and when turning it on, open one of the steam valves and turn off the cup warmer. Leave the steam wand open until it hisses or small amounts of steam or air will vent out.

Avanti stovetop exploded while on the stove


Could this happen if you fill the bottom chamber over the pressure release valve so that the steam pressure built up and couldn't be released. Or perhaps the pressure release valve got blocked. Not sure. But it is important to take it off the stove promptly when you hear it make that gurgled hissing sound that indicates the top chamber is full and now steam is coming through rather than water.

Water not coming through espresso side although steam wand works fine


you both can have same problem, solution is:

  1. low pressure of pump (or too fone grinded coffee)
  2. security valve of boiler openes to early and dont let the pump to rise pressure enough for good brewing( if it is this you can see water returning back to container if you have 2nd pipe in your machines reservoir)
