I have Futura IBA that shows car wash busy on Auto cashier. When I manually turn on the cycle inhibit on the uniop I can wash one car and then it goes back to Car wash busy and I have to manually turn the inhibit back on. The machine had been down a few days for repairs and ended up having to replace the PLC cpu and reprogram the wash cycles. I don't know if I missed something in this setup. Not sure how the cyle inhibit works on these machines. Any thoughts?
