Hi guys, I will be very grateful for any help on this.
Whenever I switch on my Vaillant boiler the control panel is completely stuck - see picture below. While the boiler still fires up none of the buttons on the control panel work, there is nothing on the display and I can't control how long the boiler is on for.
Is there any way to fix this?
