====On But Not Heating====

#Unplug the machine and open the top. Check the machine for any loose or disconnected wires. Check the steam and brew thermostats specifically to make sure the leads to them are securely connected.
#This issue typically occurs because the machine is left on for an extended time without use, or the machine experienced a power surge. Home units like this should only be left on for a maximum of 45 minutes without use. The machine should be turned off if it is not going to be used within that time.
