Zero Pressure, CAT 310

[SplashnDashRoCo]

I recently took over a self serve car wash and have been testing out the systems. For about a week everything was flowing fine, then today both pumps are not registering any pressure at all. Water is on, power is on, tested each selection and there is nothing coming out of the spray guns or foam brushes. Any advice on what this could be? Thank you!

That's most likely an electrical problem. Are the high pressure pumps not coming on? You'll need a voltage meter and will have to test for power starting at the timed load.

Since you're new at this, start with the basics.
* Check your circuit breaker at the electrical panel.
* Lk in your reservoirs verifying there is product to be picked up by the pumps
* and the number one suggestion .... check your transformer!!! If you don't have power to signal the contactors and solenoids, it's no bueno...
