Where does LR digital preinfusion fit into process of dialing in a bean?

I'll pull the shower screen and use citrus solvent to clean it tonight -- gotta get the kids to a baseball game now.

I set the pump delay to 500ms in an effort to fault trace. It exhibits the same behavior at 1000ms and 500ms. If I'm splitting hairs, the heating element turns off at 1.03 bar -- the boiler pressure does not exceed 1.04 bar, and the heating element turns back on at 0.85 bar. I haven't adjusted the boiler pressure at all.

hi lee

no issues there then

thank you for confirming that you haven't altered the boiler pressure

you might want to try dropping the delay to 100mS for higher pre-infusion pressures

kind regards

reiss.

Oh no, I’m at 5.5 right now with one of my roasts! Maybe I should bring it down tomorrow
