    I see, thanks for the advice Chris and MorganGT. I may consider doing this if i get my brother-in-law to help, he's pretty good with the electrical innards of pinball machines, so this kind of stuff should be familiar to him. I certainly don't have the experience/knowledge etc to confidently do it myself.

    To do it properly and neatly you need to tip the grinder on its side, undo the 5 screws on the base of the grinder to access the top side of the baseplate. There's a terminal strip that all the wiring runs through mounted on the top of the baseplate - you need to trace the 2 wires coming down from the microswitch to the terminal strip, disconnect them at the strip and replace them with a short jumper wire.

    You may also wish to disable the other microswitch in the doser base that restarts the grinder (when it is turned on) every time the doser star completes 2 full revolutions.

    To actually remove the switch, you need to remove the doser (2 horizontal screws at the top inside the doser with a 3mm Allen key, 2 vertical screws inside the doser at the rear of the floor of the doser with a large flat blasde screwdriver) to access the 2 tiny Philips head screws that are hidden at the back of the doser that mount the switch.

    Mazzer Super Jolly Auto upper micro-switch removal?

    Hi

    I got a second hand Mazzer Super Jolly Auto a few months back, and it's the one with the micro-switch at the top of the doser chamber, which (in a cafe/high-volume setting) stops the grinder when the doser is almost full. The unit would be approx. 5-7 years old i reckon.

    I obviously don't need this functionality in the home setting, and am wondering whether i can just unscrew it and remove the microswitch assemly altogether, so that i can get access to the chute for brushing out stale grinds etc. At present the switch assembly blocks the chute from access.

    I wonder whether you can just then cut off the wire (with the unit unplugged!) and block the hole with something convenient.

    Has anyone done this? (i've searched on the grinders threads but cannot find any reference to it)
