IC7 Spin bike question

Hi people, please go easy on me
I picked up a second hand unit for a very good price, knowing the wattrate pc wasn’t working
It might be the pc or it could be something more, I don’t know
I can use an app on my phone but if it wasn’t silly money, I’d like to get it as new
Any experience of similar
