Thanks for your help, I'll give it a look. My gut tells me that when I power washed it the meter got wet. When I pulled it I could see moisture inside. I appreciate your help.,Could be part of the problem, but you’ll have to do some electrical troubleshooting to solve this one. Here is the wiring schematic for your unit. I would start by disconnecting the hour meter from the circuit and try the unit. For an experienced tech this could be a 15 minute fix or a 3 hour trace and test. I wouldn’t throw any parts at it until I found the cause. Hour meter is $125.00+.
