When overtemperature protection kicks back in although possible causes (see error log) have been

Measures After Power Outage
After a power outage, the formation of condensation can occur at the sensors due to moisture. This can
impair the sensor function and lead to erroneous values being displayed or to failure messages (sensor
breakage, see
“Troubleshooting” on page 6-46 ).
The following measures must be taken to ensure safe operation:
1. Drain the water and wipe the interior dry.
2. Let the device warm up without water for 1 hour to 55 °C.
3. Then let the device cool down with the doors opened.
4. After this, start the device at incubation temperature according to Chapter “Start-up” on page 4-1 .
Alternatively, or when the above mentioned measures were not effective, start a sterilization run at
180 °C. Refer to Chapter
“Steri-Run Sterilization Routine” on page 8-7 .
The sterilization routine can be interrupted after approx. 1 hour. The sensors should then have dried.
