@DavecUK and all.
A Lelit E owner on Facebook told me that he has installed a 200w single pole dimmer dial, wired in sequence to the vibe pump power in (hot) wire. He says it works well, and that he can control pressure in 1 BAR increments from 1 to 9 BAR (his OPV max). This apparently allows him to do flow profiling. He says that he has not lost any other Lelit E functionality and that the machine continues to work well (after one year).
Does this ring true? Are there any downsides?
Alternatively, as per the preceding HB link, might I better consider installing a:
- High speed PWM (Khz)?
- synthesized, lower frequency, ½ AC cycle sine wave controller?
- Low speed, unsyncronized PMW (10s of Hz)?
I would love to be able to do flow profiling, which is why I’ve come back to this topic.
I unfortunately cannot afford a new Lelit Bianca at this time, especially as I will be buying another NZ for the cottage. Buying both would not sit well with my wife, who enjoys Keurig coffee and cannot understand my espresso hobby affliction (“Its just coffee!”).
Or maybe I could find a used lever machine, if we could give up more counter space, which would not sit well with my better half.
Or should I just forget the whole ☕️🐇🕳️ thing.
Sigh 😮💨 … Its a rough espresso life 😁
Just musing 🤔💭
