Er8
Bad (Open) Motor Driver - The
motor errors (Er7 and Er8) do
not cause a system error and
will not shut down the machine.
Immediately upon detection the
machine will beep twice and
show the error message. Every
time the key is pressed to
activate the dispense motor it
clears the error and allows
another attempt to be made. If
this error occurs the dump
valve still will release water.
Bad/open motor driver. Product

occurs then replace main
