My Model 8ZULWC Rachio 3 controller started making a loud clicking sound this morning. Earlier in the morning the zones all functioned and completed normally. I manually turned on one zone for a minute and there was no change in the clicking sound. I eventually unplugged the controller and the clicking sound stopped. 30 minutes later I plugged the controller in and it rebooted normally. The clicking sound did not start up again until about 45 seconds after I manually turned on one zone.
