Our whirlpool Cabrio was displaying a F51 code. I found Appliance Parts Pro website and they helped me to diagnose the problem. I found out it was a roto position sensor error. It was very easy to determine the part we needed. I ordered the part and it came the next day. When it was time to perform the repair we followed the step by step video instructions. That made the repair quick and easy. The repair took us around 30 mins or so. Thank you Appliance Parts Pro !!
