Buzzing Espresso Machine

Hi
My name is Danell, and I use a La Marzocco Linea 2EE (I think that is it) at work, and just recently, it started to make a buzzing noise when I pull shots. But only sometimes, and most of the time, I am using the hot water or steaming milk. The buzzing noise stops immediately stop the water from coming out through the group head. I was hoping you might be able to help me find a solution.
Thanks.

    I have a similar issue with our Linea 2-Group.  When I run the grrouphead, instead of a nice distribution of streams of water it all pours and sprays down the center and hisses.   Red boiler light stays on for longer periods too, but our volume is the same.  Any ideas much appreciated.  Thermostat recently lowered to 197F to try to help.

That noice is from your solenoid valve during brewing coffe.

  1. as first you should clean the group with blind filter and special detergent for washing coffe from group. if you didnt do this long time you should repeat the cleaning 3 - 5 times same day.
  2. if you follow the 1st instruction but you have the problem again you should change your solenoid valve.

To increase dispense pressure you turn the adjustment screw at the pump. When pulling a shot (use espresso) on one group the bottom needle of the gauge should read 9bars while pulling the shot.

La Marzocco Expresso g3 how do you reouble


Check the thermostat on the top of the back boiler, if the red pin is up then, make sure that there is water in the boiler then push in pin and turn machine on. Now comes the exciting part we have to find out why the boiler overheated, is it because the elements are damaged or the pressure stat is not working properly.
