Tipple Shine PLC in Coleman Hanna Super Savor

[stampedecarwash]

Hello, the PLC for triple shine function keeps working by itself. No chemical coming out in any of the bays so I dont think the issue is with one of the keys stock on the selector box. It also goes away by itself if the carwash is open. We have been closed for 3 days now due to extreme cold. Thanks

UPDATE: noticed when I touch bunch of wires in the panel this stops/starts. So there must be a loos connection somewhere, so tightened the screws where wires connect. Lesson Learned: its good practice to tighten all the screws once a year.

If they were tightened properly from the start, they wouldn't have come loose.
