Jul 13, 2015 · I've had the Buderus GB142 for several years. Most recent problem happened after we lost power in the house for just a few seconds. Since then it will not fire up and produce heat unless I press the middle button for a few seconds. It will run until the temperature reaches the thermostat set point.
