What causes 'High Pres' to be displayed on Tuttnauer 3870E?
- TThomas CoxAug 31, 2025
The 'High Pres' message on your Tuttnauer Laboratory Equipment can be due to a few reasons. It could mean the air jet is clogged and needs cleaning. Another possibility is that the heating elements are staying on instead of cycling. A faulty or dirty temperature sensor (PT100) could also be the cause. For the latter two issues, it's best to call a technician.
