So I pulled it apart to see if I could nudge the pressure up a bit (it may actually have dropped a bit from new). Anyhow, I opened it up and found a different pressure stat than the one in the Clive guide to adjusting pressure. It seems like the adjuster is waxed in place. Any ideas for getting the wax off? I just seem to be damaging the screw in trying.

I don't have a LMLM, but replace it when it needs replacing and not before. You may be able to disassemble it and fit a new O ring (Viton or FKM) for a few cents. You may even want to replace it with one of the more expensive memory metal vacuum breakers.

Sometimes we 'think' too much about coffee. Perhaps the best 'Prep Tool' a Home Barista has is their accumulated experience and intuition.

La Marzocco recommends annual replacement of parts that regularly last 2-5+ years in a home environment. If you have to do these maintenance order to fulfill some warranty requirements, then just do it till the warranty is expired... But... A Vaccuum breaker will start to hiss when the seal has hardened and isn't able to work as it should. It's quite noticeable. They usually last 2-5 years. I woul...

Somewhat unlucky. You have a heatsink that needs to be drilled out (the two rivets). The X caps look like the gray block looking thingies on the PCB under the heatsink. You could see that the parallel resistors are marked R1 and R2 and RN1 and RN2 and are in parallel with the capacitors. Also - the 1000uF 10V electrolytic (black through hole) capacitor may also be the culprit. It is probably the c...

that's a good point but I'm not so sure it would have an overall negative impact. Smaller particles may migrate downward where bigger particles would migrate upward (but maybe that's backwards) and the longer you "vibrate" the more they are going migrate. Where the smaller particle end up (top or bottom) is going to make it more dense and its going to have an impact on the flow with will...

ok so this is what i got so far: 1.charge temp : 174~220c, how do i know which one is the best? 2.soak for 1 minute or so... 3. turn up the gas...to which level? (i used 0.7 at my second posted graph) 4. let the roaster develop by it shelf and dont tought it to match 5.use costant air flow-flow, when using smaller batch size turn the drum RPM down to around 20-25, if not then 50-60 6.dumper settin...

I've had the LMLM for about a year and I'm looking at doing the annual PM. I can easily replace the screen, screw and group gasket. How often does the vacuum breaker need to be replaced? I think there are members here that have had the LMLM for about 5 years now and I would love to get their feedback.

Yeah, I totally agree with the overall "like" of the brand and those two coffees. Both their Balanced and Bright selections are excellent and I agree with the descriptions. I had written them off after trying them a few years back when I had an ailing grinder and different machine. Either the Monolith/Linea Mini has made a huge difference (duh) or I had gotten a batch that didn't work fo...

Interesting about no further mixing required after grinding into a separate container. I can see how that might be. Although I haven't found it particularly bothersome to give it a few whisks with a little cocktail whisk. I have been RDT'ing since before Kafatek existed. So I already have my little glass martini spritzer. I never even unwrapped the one Denis gave us. -Peter
