Rancilio epoca e 2 group discharges steam out of safety valve what will cause this issue

Hi Ewah,

If you are getting steam from the group and no water when you turn on the water button - then you may have a group blockage.

The fix depends on the type of machine you have.
If it is a commercial type - then call in a qualified coffee technician.
If it is a domestic type like rancilio sylvia, the you could try to descale - maybe too late, but worth a go.JURA descaling tablets
If when descaling, no water is coming from the group try leaving the steam tap open when asking for water.That way you may get the descaler liquid moving inside the boiler and it may clear the solenoid valve blockage.
If no joy with that you may need to replace solenoid valve.

Domestic machines need regular descaling to avoid group blockages.

Hi Daren,
You could replace the whole steam valve wand but you don't need to.
The rubber grommet inside the steam valve is worn out and the tap wont close properly - that is why the steam is coming out.
You will find these parts with a commercial rancilio supplier.

Solenoid valve OR dirty and blocked shower screen OR dirty and blocked jet OR crap in the line to the R/H group..



Simple fix if you are in Brisbane.

You will need to get that manometer changed. Get a hold of a rancilio dealer and tell them you need a steam manometer.

The only thing that comes to mind is the metering jet on the group as well as the reducers on the tubes bringing water into the group.

Hold down right most button for 8 - 10 seconds, then press button to program when you get your volume press button to stop repeat for next buttons, when done press stop button to get out of program mode.

Your boiler is flooding because the water level probe is not behaving properly. The machine thinks it needs water.

The vent valve is stuck in the open position, leave the steam wand open, while the machine is heating until you hear it hissing, then close steam wand and machine should heat up properly. Replace the vent valve as soon as possible.

It is possible that the reset connected to the boiler tripped.

It's the thermostat for certain.

Te release valve is put there it be sure the tank pressure doesn't get too high such as to cause a steam explosion/rupture of the tank.
