Hello all, I have a Mahlkonig K30 ES (stepped version) for sale. This grinder was up a while back. I ended up keeping the grinder because I finally got some time off from school and wiggled some time from work and was able to figure out the problem with the grinder. As I had mentioned earlier in the previous ad the power board might need replacing. Sure enough it was the power board and also the circuit breaker fuse as well. I got those parts in and was able to replace them and sure enough the grinder was up and running. Keep in mind this grinder was used in a commercial setting so it shows signs of wear. I think some one interested in this grinder could probably use it as a project grinder, by refinishing the exterior and doing some customization as well. The hopper does not come with the grinder. My asking after parts is $650, I am asking so I am welcome to offers.
