catmastertech :

Have you tested the harness?

catmastertech :

Most electrical problems are due to connectors or wire failures. The solenoids rarely fail, some may stick but, this usually doesn't give a failed solenoid code.

 

Sorry, I cannot get the chat window to work on my end. I must change to this format to continue.

 

If you will send me your serial number, I might find more information on this machine to help. Some markets I cannot access but, most of these are the same so, it should be easy to find.

 

How are you viewing the codes?

What codes have you recorded?

Do you have a service manual and electrical schematic for this machine?

 

Please let me know what you have done so far and I will be glad to help more.
