Hi:
Have a dual boiler brewtus vibration pump model. Can make espresso but no
pressure or steam. Looking for a steer for how to diagnose the problem.
Thanks,
Justin

Quick guess is the heating element

Get out your volt meter and watch some basic troubleshooting:- making sure
the proper voltages are present at boilers, static relay, etc...

If there is no pressure or steam - it is probably the steam boiler
pressure sensor/switch. These devices first power the steam boiler up,
when it gets to pressure then it cuts over to the brew boiler. So it
sounds like it *must* be failed in a hard stuck over to the brew boiler
state. Otherwise, if there is no steam, there is no espresso :)
Easy fix, and easy to check - multimeter rated for mains voltage. There
is a common wire and then two others - one to the brew boiler heater and
one to the steam. THESE ARE ALL MAINS VOLTAGE. It *will* kill you. So
some care is needed :) The alternative is to identify the brew and
steam boiler leads, then with the machine off AND UN-PLUGGED FROM THE
WALL do a continuity test between the common terminal and the steam
boiler terminal. Should be continuous. If it's open circuit, it is not
working. The third way is to simply swap the brew and steam leads,
power up and watch the pressure - if it rockets up past normal, kill
power and open the steam wand - the pressurestat is toast.
Cheers
