The blower intake fan was getting sticky so I removed it (caveat - you may void warranty; I'm an espresso machine technician so I forged ahead in an intrepid ... way) and soaked the cowl and fan in super hot water and two big tablespoons of Caffeto. Hot rinse; air dry.

Nice and clean. Apply high-temp food grade lube on pin shaft, ensure e clip in groove; thin wipe of Inox electrical lube on rotor (it's a very corrosive environment here by the sea) and reassemble.

Dry burn. Ready for another 125 roasts!
