I just got a Weber Key grinder. The recommended grind speed is about 70RPM. It takes about a minute to grind 16g. My previous grinder, a Baratza Sette 270Wi sounded like it ground at 10,000RPM. It would grind 16g in about 10 seconds. I'm gladly giving up that speed for the super quiet grinding of the Key. Its speed range

That is a control solenoid disconnect. It should have a screw going through it to keep it attached to the solenoid. Inside should look something like this: {image} If it has only 3 prongs ensure sure those 3 prongs mate up to the three prongs on your solenoid. Maybe you can find a wiring diagram and go through

I am actually stoked for the new Mazzer burrs, but I would like to know if Option-O or SSP burrs fit the Philos

I reassembled last night. The NOS pump leaked a little bit at line pressure (I am using a 2 bar regulator on the water feed), I pulled it apart and applied keg lube to all the seals, doesn't leak any more but I will keep an eye on it. I am hoping with a little run time it will wear

I grind 16g at their recomended speed of 75. It takes around a minute. I would guess 60-80g would take four or more minutes. The feeder didn't struggle for my 16g, just slow and steady
