Rocket Cellini Evoluzione - How to replace steam tap?

There was a groove in that brass rod for the circlip, and the rod broke off at the groove. The circled bit is what broke off. You need a new valve rod. Your part breakdown doesn't show it but it should be available from Rocket or a Rocket spare parts supplier. I recently got one from

Molar Z Grinder

Not just yet! I'll have more time to experiment next week so I'll give it a try. I haven't had any 98mm burrs (yet) so can't compare. Thanks!

Black and White Classic help

Tried letting the ground coffee sit for a little bit before extracting. Made it worse. Now 18gms runs thru in 13 seconds. I think one of 2 things has happened here, either this is just a bad batch, which I've had happen with other roasters, or this coffee just isn't going to work with my setup. I'll just

Olympia Club pressurestat malfunctioning

I bought some spare bellows from Migg last time I bought a spring from him. I identified US based source for the microswitch that is used in this marvelous device, but I can't find it right now. I think the manufacturer was Temco, but I am not certain. Migg might have them as well?

Good sealant for heat exchanger and heating element?

Anything that holds up well at high temperature. And easy to remove. It seems that permabond A131 is a good fit used by some manufacturers but they are hard to get. I've used loctite 542 but they adds to the difficulty to removing. Also any problem with using an impact wrench to remove? Will there be any

Auto-fill not stopping - Bad controller?

And if the flow meter is fed through the voltage regulator you would want to do preceding test for voltages between pin 1 and the ground lug of the 7805.

Auto-fill not stopping - Bad controller?

Try jumping the pin four level sensor wire to the pin two ground wire and not the machine ground. This is the path of least resistance. You can loosen the four pin Phoenix connector and insert your probe wire. This should shut the water off. If it still runs on then measure the resistance of pin two to the top

Rocket Cellini Evoluzione - How to replace steam tap?

Hi and welcome on HB. You have to replace the whole shaft, the part you circled in red is part of the shaft that got worn by friction, not a separate part. If you want to do it by yourself just watch this video.{video}

ACS Vesuvius Evo Leva - Consecutive shots and long shots

K-Type thermocouple like this {image} Of course it is a steady state temperature. The time and how to measure It depends on the machine and thermofilter you use. When the needle valve is full open, the flow rate is high so the grouphead cannot be filled. If the time is too long, the boiler will be cooled down and
