Most of the time, it is the guarnizione sottocoppa, the group rubber gasket that has become stiff or worn. Sometimes, it is the filter basket that has been flattened or nicked from not using a proper battifondi, or knock box, and as such is damaged and will not form a good seal.
Last on the list is a worn handle, specifically the "ears" that you guide into the group to make the seal. When connected to the group, the handle should point to 5 or 4 O'clock. If it points to 3 or maxes out, this may be remedied by ordering paper spacers (shims) that are to be installed first, then the new gasket. Usually 2 shims do the trick.
check the oil pressure first, it should read around 10 to 14 psi. If pressure is inside the range then your pressure sensor is bad. If lower or reads 0 psi your got a engine problem, further diagnosis needed.
Good luck.
The gauge is connected with pump water output with a very thin pipe called cappilary pipe. So if any dirt that is comming from the water supply can blocked this cappilary pipe and if this happens during the pressuring phase then blocked a pressure of 4 bar inside the gauge. So if you desconect the cappilary pipe behind the gause the you should see if any water comes out from cappilary pipe. If not you can remove it also from the side of the water pump and try to clean it by blowing air from the side connected to gauge this can clean it perfectly. The you can conect it back together. The you will read normaly the pressure of the water mains and during making easpresso pressure of about 9 bars. If you dont have any change in the gauge after performing above the gauge might be the problem.
