From the manufacturer:
About this machine:
A great machine, that lasted in my mid-volume roasterie/cafe for 3 years. Well maintained.
Selling as is. Group 2 has a W38/40 error reading. This is for the temperature probe which helps operate the variable temperature profiling on group 2. Even with the error, we crushed our morning rushes with this machine.
A little love from a competent tech (and a couple hundred bucks) will have this workhorse cranking away in no time.
Contact me if interested.
