Kickr spin down issue


I have a Kickr I purchased off of a friend, it works just fine…I am using it currently via the Wahoo Fitness app. I wanted to perform a spindown calibration but when going through the procedure it would not display speed. I called Wahoo today and they said it was end of life nothing that can be done.

Is there anyone in the UK that can service the Kickr for me as I suspect the internal speed sensor has gone (if it has one).

Thanks in advance
