What does Schaerer Timeout coffee heater mean?
After the machine is switched on, each boiler heats toward its set temperature. The control allows 4 minutes for this. If the coffee, hot water or steam boiler has not reached its set temperature in that time, the machine shows the timeout message for the boiler named. The manual lists one cause: the set temperature was not reached within 4 minutes after switching on. The operator steps are to switch the machine off and on, and to make sure the grounds bin is in place, since a missing bin can hold up the start-up. A heater that cannot get a boiler warm in time may have a failed heating element, a heater control that does not switch on, or a temperature reading that is wrong. Those are for a technician.
