    OPV only adjust the pressure of the brew water. It's not related to the steam pressure. thermocouple is the temperature sensor used i commercial. In brew priority, the machine uses the brew head thermocouple to set the temperature of the boiler. if there are short circuit between the 2 different material wire, it will sense temperature outsidebthe brew head which is much colder. Thus the heater will keep heqting up the boiler and causes extremely high pressure. Try to switch to steam priority and see if the pressure can maintain. In steam priority mode, it uses the thermocouple in the steam

    Hmm... sounds like a brew thermocouple short circuited halfway.
  3. U need to inject air into the milk by lifting the tip of the steamwand to almost touching the milk surface. Procedure. 1- reat the steamwand on the spout. rotate the milk pitcher clock or anti clock wise so that the tip is at 9 oclock or 3 oclock with and angle while still resting on the spout. 2- submerge the tip to the separation line of the steam wand. start steaming. 3- When u see the vortex forming, lower ur pitcher till the tip of the steam wand almost touching the milk surface... U hear psssttt psssttt sound. that's air injecting into the milk. continue for about 15-20s then lift the p

    Hi everyone, does anyone knows the steam boiler pressure of all 3 temperature settings in the brew priority mode?
  5. Hi... I don't have a specialita. But I have an Eureka Mignon Mk2. This is how I do it. I have the adapter machined from aluminium and the top funnel 3d printed. The bellow is brand new silicone boot for car pwer steering. Sent from my SM-N975F using Tapatalk
  6. 15 bar is only the maximum pressure the pump can supply. Therefore, in order to achieve 9 bar of pressure, you will have to dial in your grinder accoding to beans type and roast togher with good puck preparation to provide just enough resistance to produce 9 bar of pressure through the coffee puck. If you think you already do your best to prepare the puck, there's still an OPV to tune down the pressure Sent from my SM-N975F using Tapatalk
  7. I think most of them are produced from the same factory. Even Crema start selling those. I think Pullman used to machine the original portafilter and sell them. Thicker material. But they too sell the thin wall now. They just change the handle.
  8. I am using Mignon Mk2. The only differences from the silenzio is the desinged bigger body to incoporate sound insulation material for noise reduction. There's also an anti clumping screen at the inlet of the chure to break the clumps. adjustments and burrs are the same.
  9. No. The 65mm won't fit into the Mignon with 50mm burr. Sent from my SM-N975F using Tapatalk
  10. I was actually asking the 50mm. Are there any difference between those Mignon with 50mm burr. Example Mignon Mk2, Perfetto, Manuale, etc. Sent from my SM-N975F using Tapatalk
  11. Thanks DavecUK. So, meaning there's no difference in grind quality between those Mignon with 50mm burrs. Maybe just the dial adjustment screw thread pitch. I don't believe it can. Sent from my SM-N975F using Tapatalk
  12. I'm using Eureka Mignon mk2. I would like to know if there are any differences between the burrs of Mk2, Perfetto, Manuale etc which utilizes 50mm burrs? Thanks. Sent from my SM-N975F using Tapatalk
  13. I've learned that there are 2 types of E61 portafilter. Difference is 1mm thickness on the wings. Sent from my SM-N975F using Tapatalk
  14. thanks. will keep an eye on your channel then. Sent from my SM-N975F using Tapatalk
