Breville Dual Boiler Glitch?

OK now you're talking... :wink: While I do not want to goad anybody into living with a machine that is not working the way it is supposed to, IF you do the "Slayer mod", you will not need the pump to run at partial power for pre infusion. You run the pump at full power and you set the flow (and or pressure) as you wish using the needle valve. An by the way, I too have mine plumbed AND ri...

Every Espresso is Sour - Please Help

Pre-infusion is merely a crutch/training wheel and far from necessary for great espresso. Might help channeling for some, but that's just an indication to work on puck prep. 'Might' be acceptable to bring out something consumable with the light roast/underdeveloped battery acid 'coffees' that some seek out, but I'll never waste my time/effort with that venture. More power to those that choose to d...

Brix to TDS conversion coefficient.... 0.85 or 0.79???

I think the reason is almost always cost. People have or can afford a refractometer that reports in Brix and they want to use it with their coffee. If what I tried to figure out above is true then you could use it, adjusting for the concentration you expect or initially calculate. Probably the temperature matters too (?) so best to measure samples at or very close to 20°C. I think I read that ...

Breville Dual Boiler Glitch?

I am going to have to look into the Slayer evolution. 20 years or so ago, I picked up a CMA single group(unbranded), E61 semi automatic machine that was probably about 2-1/2 times the physical size of the BDB. Massive single boiler! I had it plumbed in and rigged a switch to open the three way solenoid to line pressure without engaging the pump. I'd flip the preinfuse rocker switch for a few secon...

Decent 1+ year on

If you resist the temptation to fiddle with all the parameters it is a very easy machine to use. Initially choose one preset - gentle and sweet is quite forgiving - and don't fiddle with anything on the machine. Then adjust grind and dose for your coffee, as you would with any other machine and just use it. It now has a stop at volume function, which means you don't have to watch the pour. (It can...

Vibiemme Domobar Not Heating

So, with a multimeter set on resistance, when I touch the leads to the heating element, I get a '1' indicating very high resistance. What I see online suggests it should be close to 20 ohms. does that indicate a faulty heating element? NOTE: do I first need to disconnect the wires to these leads before measuring? And, if it is a bad heating element, should that be under warranty for such a new mac...

Brix to TDS conversion coefficient.... 0.85 or 0.79???

approximations are what we use for most measures and as long as it's reasonably good and has a predictible offset that's fine... I mean IR thermometry used a dreaded compensation factor, to cope with different materials emission and it's not that when I measure the length of something that I go get the standard 1 meter platinum rod from Paris. Personally I see not much point in TDS nor brix measue...

Best Thermometer for Mac

Are you using the original serial to USB cable? I have not many more ideas. I know this works for a number of users. I myself do not have a Center301 at hand to test. Sorry.
