If I am correct dial valve 2 failure is related to valve 25. Either the valve, x25 on the distribution board the driver on the actuator brd or once a bad software chip (heard from another tech)

dial valve 1 is valve 24 
dial valve 2 is valve 25
dial valve bypas is 26

Pls let us know what it is.

Cheers.

Your honor, your word and your skills you break any of those and you will drum out within 3 months
