ECM Synchronika: dual boiler, PID temp, 3 way solenoid valve. Notably it has $400 upgrade wood accessories (steam/hot water, main handle, and portafiler). I have original box to transport with too. I added a flow control valve, temperature monitoring at the group head, and pressure monitoring at group head. All will come with purchase. Only ever used filtered water. Cleaned monthly. I can provide cleaning solution if desired.
I’ve used it daily for 5 years and has always produced great coffee. There is a small water leak under the machine when it’s turned on. I’m selling to upgrade to LMLM.
