What to do if my Heinner HBM-900WHBK displays "H:HH"?

If the Heinner Bread Maker displays "H:HH" after pressing the start/stop button, it indicates that the temperature inside the bread maker is too high. To resolve this, press the start/stop button again, unplug the bread maker, remove the bread pan, and leave the cover open until the bread maker cools down completely.
