Rainbird ESP Modular Controller M rain sensor problem

We have a system that was installed about a year ago, working fine. We've had the rain sensor on "bypass" mode until recently, during a rain, changed the setting to "on". The problem is, the watering programs never resumed even after it got warm for several indicates the sensor is wet (red light), so we finally set it back to "bypass". We plan to be gone for a month soon and would like for the rain sensor to be working while we're gone. Does anyone have a suggestion?

Take a close look at the rain detector. If you can't get near it, then bypass it.
