  1. Lelit Forum
    My Mara PL62 started sending a lot of water back to the tank, the tank got very hot, and thus the pump started often as well. I thought this had to be the 2way solenoid valve and replaced this now. There is still some smaller amount of water leaking to the tank when not operational, but less...
  2. Gaggia Forum
    Hi all! I mounted my pressure gauge to my portafilter to my Gaggia Classic 2002 today because I wanted to adjust the opv valve. I have tried as best as I can to turn the screw of the head of the opv valve, but I found out it to be stuck. No matter the force applied I could not get it to...

    Having had my GC apart for the first time I'm now both better informed about how it works, but also slightly confused! It's generally of no importance whatsoever other than for my general understanding, but I'm particularly curious as to how the OPV and the "overflow" work with each other. As...

    This will allow you to accurately adjust the OPV pressure on your Gaggia Classic is similar. Remove the spout on your PF and this attaches in its place. Fit the PF, but brew switch, and read the pressure output. I used regularly on my Gaggia to adjust pressure up and down for different...

    I have decided to sell my roughly one-year old Gaggia Classic 2019 (also called the Pro, Model Number: RI9480/18, Serial Number: TU901842081344) here in the forum (coming here directly from the Valuations section). It works perfectly, never had any problems with it, the only reason why I am...
  7. Sage Forum
    I'm not clear why Sage designed these machines to run at a higher pressure than most - it must have been a deliberate thing but I'm not sure what the benefit was supposed to be. Anyway, a few days ago the tank on my BE happened to run dry in the middle of a shot and I lost pressure. I had some...
  8. Gaggia Forum
    I hope that someone can guide me in the right direction. I've been reading lots of articles and watching loads of YouTube vids about how to make an espresso with my old Gaggia Tebe, that I rescued from gathering dust in the garage. I've had it in pieces (since it wouldn't pump water through...

    Hi all, I would like to find out if adjusting the OPV on the 2015 model is the same process as the older model, in that you remove the large brass connector thing and then use a 5mm hex to adjust behind? Many thanks in advance for your advice.

    I've had a bit of an odd outcome every time I try to check the OPV setting on my ISOMAC Millennium. I have a pressure gauge that I fit to the portafilter. When locked into the grouphead, water somehow flows past the grouphead seal so I can't get an accurate pressure reading. When I do normal...

    What pressure should I be reading on the brew head pressure gauge on my Minma? I think it might be a bit high at 9 bar. Where is the OVP and how it it best accessed if I need or want to adjust the pressure. These are probably rather naive questions, but this being my 4th express machine but...
  12. Rancilio Forum
    Can anyone point me to a UK supplier of a OPV (looks like I have a v3 as it's adjustable) OR a refresh kit It would appear the gasket within the OPV is severely degraded, and the hex nut doesn't look great (may be pierced?).

    Hi all, I would like to pick your brain as I ran into a dead end here. I have a V3 Silvia (2009) that I pretty much refurbished bit by bit. The problem is that I'm getting water dripping back on the return hose as the machine heats up, steam also escapes there. The first heat cycle is silent...

    Hi, I've tried searching but not finding the info I need. I've got an Isomac machine that uses the E61 group head. I'm in the process of an overhaul and need to replace the OPV (expansion valve) so need to adjust it to the right pressure once all together. I have a pressure gauge but need the...

    I've been watching eBay for a suitable Baby as a project, and the model I wanted was the one with 4 square buttons across the front, which should date from around 2004. So bought one and waiting for it to arrive. I wanted a Baby since the top comes right off and it's easier to work on than a...

    All, trying to get my head around the reason for adjusting the OPV on my new to me Gaggia Classic. I've done a whole bunch of searching, but nothing that exactly answered my question. Closest I got was here. Right now I am trying to dial in the tamp/grind/dose to just get flow through the...

    So, i've been reading a lot about pressure profiles for espresso and had been having issues with my Oscar II shots, so decided to purchase an OPV. (I can post a guide if anyone else is interested, and yes, I do realise the Oscar can't pressure profile..) Before installing I took a reading of my...
