I bought a Lelit Elizabeth about 6 months ago from Bella Barista. The OPV is set out of the box at about 9.5-10 bar. I haven’t seen any need to adjust it. I have one of the coffee buttons configured to deliver about 3 seconds preinfusfion using the pump to gradually increase pressure to 9 bar. The other is set for 4 seconds preinfusion using steam to hold the pressure at 3 bar for approximately 6 more seconds then up to 9 bar for the rest of the shot. I can switch off the steam boiler and alter the way the second button works at the press of a button on the controller. I drink mainly espresso or long black so if I’m not using the steam preinfusion I keep it switched off for economy. If I want steam milk it takes minutes to be ready from switching the steam boiler on. The machine has had its default controller settings adjusted according to the documents that Dave C has produced and I’ve been extremely happy with how the machine has worked without me needing to play around with it.I am constantly changing the coffee beans I use and have found I get really good drinks by just adjusting the grinder settings (Niche Zero) and keeping the machine set - only changing one variable if at all possible. Life is too short to mess around seeking perfection in a drink if what I’m getting is good. Bottom line is I would happily get another Elizabeth if the one I have failed although I don’t expect that to happen anytime soon. I also drink coffee using other methods (see signature) but that’s not relevant to this topic.
