Everything You Ever Wanted To Know About The Tuttnauer Door Bellows (And Then Some)

The function of the Tuttnauer Door Bellows Assembly is to insure that the Door remains closed while there is pressure inside the Chamber.

How The Tuttnauer Door Bellows Works

The Door Bellows Assembly is located in a cavity of the Door, in the area which is engaged by the Closing Device.

There is an access hole, to this cavity, in the face of the Door. As steam pressure builds, the pressure is allowed into the bellows cavity and expands the flexible Silicone Bellows.

This pushes the metal Locking Pin out through a hole in the Housing Bolt and into one of the notches on the Closing Device. This locks the Closing Device and prevents the Door from being opened while pressure remains in the Chamber.

When the pressure in the Chamber is released, the spring like action of the Silicone Bellows pulls the Locking Pin back releasing the Closing Device.

How Do You Know If Your Tuttnauer Door Bellows Is Bad?

Indications of a faulty Door Bellows include (While Running A Cycle):
  • Leakage is noted around the center of the door or around the latch
  • Puddling of water on the counter below the Closing Device
  • A Whistling Noise
Also, a "LOW WATER" Warning Appearing On The Display can be caused by the Door Bellows allowing water or steam to escape at a higher than normal rate
