On But Not Heating

1. 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.
2. The high limit switch of the machine may have tripped.
3. If the machine is still not heating then the high limit switch will need to be replaced.
4. This issue typically occurs because the machine is left on for an extended time without use, the machine experienced a power surge, or the boiler wasn't refilled after steaming. 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. Additionally since the machine does not have an auto-fill function it is important to manually refill the boiler after steaming by using the hot water function. If the boilers becomes too emptied it can trip the high limit switch or damage the heating element.
