Report "The machine was working fine until the trouble lights started to flash after I started the machine was turned on one morning. I turned it off and waited 30 sec just like the manual asked and showed the same lights warning. Seem like the brew group is making the initial cycle but instead of stopping in the neutral position it ends up in the marc dumping stage. Is it a common problem? Is there an easy solution? Thanks for any help you can provide. No more waranty"
