    Hi,

    I need your help removing the PCB from this Wilo Yonos Para SD15/6B PWM1 W MC Pump.

    If anyone has experience with this pump, any advice would be greatly appreciated.

    AI: Could you describe what’s preventing you from removing the PCB—are you stuck at a particular step, or is there a specific part that’s difficult to detach?
    I feel like I have to pull on the PCB to remove it, but I am afraid to break it in the process. Do I need to desolder and unclip a few components in order to remove the PCB?
    AI: Have you already tried any steps or do you have access to a service manual or technical documentation for this pump?
    I just removed the back cover. I don't have access to documentation.

    I have no experience of these particular ones, but I'd start by vacuuming out the red ones, looks like windings. Check if the pins (green) don't hold, examine the purple one somehow, could be the connectors.
    PS.
    Do you have a lovely hole in the blue IC?
