Thank you guys so much for responding!
I disconnected a lead to the block on the motor on a recommendation from Roger (lead LM tech). He instructed me to cap off this wire, shut off the water inline ahead of the machine, and use the group solenoid to let off any positive pressure remaining in the brewing boiler.
Power off, service done, wires reconnected, water line opened, power on.....no motor response.
Going in right now to check the fuses and transmission of power with the multimeter.
More to come.
