So i bought a car wash with razor IBA. Nearly daily I get a fault F70 speed controller 1 lost communication. I have been working with distributor via phone and have tried a few different things but no luck. Does anyone know what could be culprit? Wash was installed 2022. It will run presoak across front of car and when it's time to make turn down driver side it just shuts down...
 
Have you called manufacturer tech support? They usually have a good idea of stuff to check/replace based on which code and how you get the code.
