Has anyone experienced trouble with their 1290 TCC G1316C? I am receiving an error message that the valve is not switching. I am using a 2pos/10port 1200bar valve

 Hi, valve if not switching (where we get error for valve failed) issue is generally with column switching valve or in some cases might be the main board

Hello, thanks for the response.  The repair has been made.  There were three possibilities.  The problem was actually the actuator valve.  The main board and the valve head were fine.
