      If your Tuttnauer Laboratory Equipment displays ‘Low Pres’, clean the water level electrode inside the vessel. Also, check that the door is fully closed, the door gasket is seated, and there is no steam leakage; replace the door gasket if necessary. Finally, check the leveling of the machine.

      If your Tuttnauer Laboratory Equipment displays ‘High Temp’, clean the air jet. If this doesn't resolve the issue, it could be that the heating elements are remaining on instead of cycling on and off, or the temperature sensor (PT100) is faulty or dirty, in which case call for a technician.
