I have run into that before and it was the display battery.
Hi ORDA!
Thanks for your attention. Yes it is strange,but is true.The display shows a weird symbols and the clock settings and some other parameters are reset each time i disconnect the battery!Friends told me in this forum that it might be the 3.6v battery memory of the display,or the display defective.
To start,i´ll change the 3.6v battery,lets see!!!
What´s your opinion about that?
Best regards!
PM code is overheating of the pump motor (sensor mounted in the motor), it is very strange that only the tilt function is not working good.
