The most common "no watering" hardware related issues our RainMachine users are reporting are mostly linked to irrigation valves being stuck or malfunction, no water flowing in the pipes for a long period of time, and power line failure on the RainMachine device location.

These type of issues ends up with the RainMachine device rebooting or stopping irrigation to protect itself. You should also check possible software configuration issues as explained in this support article.

Most common hardware-related issues are:

1. RainMachine stops watering or reboots immediately when starting watering a zone.

This usually happens when a valve is stuck or electrically broken. A notification about this electrical short will be sent to your phone. This can happen to a certain valve/zone or a group of valves, remove the wiring of those valves from RainMachine and check/replace the valves.

2. RainMachine stops watering or reboots after a zone was running for a longer time

Check if the water is flowing through that valve running the zone manually from the RainMachine interface.

Please check your valves integrity and wiring, if you have a Master Valve check its settings from the RainMachine mobile/web apps, or if your irrigation system connects directly to the water line check for possible outages and also check with your electricity provider for possible issues on the main power line.

3. RainMachine history logs show that a program only runs for the first zone(s) and after that, no zones were watered.

This is most likely a power failure. If a power failure happens during a scheduled watering event, the event will not be restarted but a notification will be sent to the user phone if RainMachine device starts up in the next 15 minutes. This is to differentiate between large power outages and outages because of something that happens in a short time frame during watering. 

Larger outages can be detected by inspecting RainMachine uptime using RainMachine mobile/web app and open Settings - About.
