Rain Bird ESP-6TM Counting Down but no water Flow
My Rain Bird ESP-6TM with 6 zones has been working fine for the last 5 years. However, last weekend, despite the controller counting down....water isn't flowing. Here are the events...
Short (but heavy) storm about 8 days ago
Went to turn on system but had NO DISPLAY.
Opened controller and trouble shot...two things found.
1. Battery was not enabled (tab preventing connection still installed since house was built)
2. Fuse was blown. Changed fuze. System reset like normal.
Went to start system. System appears to be starting (Zone 1 counting down) but no water flowing.
Manually advance through other zones...all the same...appear to be counting down but no water flowing.
Trouble shooting 1: Checked voltage through COM & Zones...voltage is sitting around 25 on all
Trouble shooting 2: Checked the relays to see if there is water. When I turn the solenoids of the relays...water flows.
So looking for help. Any ideas wold be appreicated. I'd be especially interested in how I would disconned the rain sensor or test if that is keeping the water from flowing. But that seems strange given that voltage is flowing when a zone is one. Beyond the controller...where are the common points of failure that would cause all zones to fail?
Thanks for any help!
