i am working with a BIAlite ugrade system. It worked fine for 20+ Years. However since wednesday the system displays a temperature failure.
The temperature is not longer constant. It varies from 24 to 27°C. The room temperature is constand at 22°C. I looked in the handbook, but there is no hint how to solve a problem like this.
Does anybody have an Idea or a suggestion how to repair the maschine?
For me looks like an hardware problem.
Temperature sensor is broken or a malfunction in the cooling/heating element.
Contact the service to ask if you can do any diagnostics before they come.
Probably you have to replace some parts ...
Thanks for your answer.
For me it looks like the sensor. It changes from 24 to 27 °C in one second.
I disconnected the sensor, used contact spray and connected it again. Now i have to wait a little bit to see an effect
Service for this old system (25 Years) is no longer available
