  If the drain of your Tuttnauer Laboratory Equipment is clogged: 1. Open the drain by turning it counterclockwise and place a heavy object over the reservoir cover. 2. Blow compressed air into the drain to force debris back into the reservoir, then clean out the reservoir. 3. Alternatively, disassemble the drain valve, clean it, and blow out the line. Reassemble the valve, ensuring the large 'O' ring is properly seated.

Why does Tuttnauer 3870E show 'High Temp'?
- D
  Daniel RossAug 30, 2025
  If the 'High Temp' message appears on your Tuttnauer Laboratory Equipment during heat up, it could indicate a faulty temperature sensor. Alternatively, the heating elements might be staying on continuously instead of cycling on and off. In either situation, it's recommended to call a technician for assistance.

  To address a clogged drain in your Tuttnauer Laboratory Equipment, open the drain by turning it counterclockwise. Place a heavy object over the reservoir cover, and blow compressed air into the drain to force debris back into the reservoir, then clean out the reservoir. If needed, disassemble the drain valve by turning it counterclockwise past the stop point, remove the valve, clean it, and blow out the line. Reassemble the valve by turning clockwise, ensuring the large “O” ring is pressed into the groove on the autoclave.
