My machine is a Bezzera BZ10. The reservoir has three white silicone tubes. One feeds the pump. The other two smaller tubes come together in a Y-connector and dump back into the reservoir.

With a blind basket, the pressure gauge shows 12 bar. I expected water from the OPV to...

So a couple months ago my Barista Express got the not-uncommon buzzing and low pressure that's usually due to a bad solenoid valve. I ordered a new valve which was backordered for 2-3 months and just did the replacement, but I still get the same buzzing and low pressure during a...

Hello,

Do these dents around the pressure safety valve look detrimental enough to warrant punching it out (as I've seen some people do on this forum) or source a new tank? The supposed problem is that the pressure valve fittings won't seal/tighten onto the tank because of them....

Refurbing a 2011 PL41, and there's some leaking around two of the plumbing joints. How essential do you guys find the thread locking glue in this regard?

Hello! I'm a relatively new (1.5 years) owner of a Bezzera BZ13 and recently started seeing some strange behavior from it. It has worsened over time and I'm hoping you all can provide some insight into what I should do next.

Over the past 4 weeks I've noticed increased activity...

Hi all,

My QM-67 is behaving like the water tank is empty, even though the tank is full and the floaty is touching the top screw. I took the screw out and cleaned it, as well as the tank, but it's not coming back on. The power switches are on, but the PID isn't, and the pump...

Hello everyone! I'm new here as I just acquired an Oscar ii for a steal. It's producing great steam pressure but the water at the grouphead stays around 140F. I've descaled the boiler and heat exchanger but the water coming through is still not getting hot enough. If anyone has...

I have owned my Pro800 for a few years now, have always kept it clean and regularly maintained the group (new seals annually). Beyond that, the machine has not undergone any maintenance or repairs. Has only had Crystal Geyser bottled water (Mt. Shasta source).

I've been in...

Hi all - I have a 9 year old Expobar Office Control that does not flow any water when I press the brew buttons. If I test the pump directly it will produce a very low flow, 75ml per 30 seconds, but if I bypass the flow meter it will pump water as per specs - about 300ml per 30...

Hi: recently the brew pressure on my pro 500 PID has been unexpectedly dropping but it's not consistent. Sometimes it drops from 10 bar and fluctuates between 5 and 7 bar when making coffee. This doesn't happen at all when I use the blind disk and the brew pressure it at 10...
