Follow a calm troubleshooting order when a system fails

Most failures are simple: a tripped breaker, a flat battery, a clogged filter. A fixed order of checks keeps people safe and finds the cause faster.

How

1. Make it safe: if there is smoke, fire, gas smell, burning smell, water near electrics or anyone hurt, leave the area and follow the emergency plan (safety module).
2. Check the obvious: is the battery low, is the tank empty, is it simply dark or cloudy, has a breaker or fuse tripped, has the low-voltage disconnect cut in?
3. Read the monitor and any error codes, and look them up in the manual.
4. Check the logbook: when did readings start to change, and what changed around that time?
5. Reduce load: switch off non-essential loads and use the backup (generator, stored water, pantry) while you diagnose.
6. Do only safe user-level fixes: reset a breaker once, change a filter, clear a blockage. If a breaker trips again, stop.
7. Call the installer or a qualified professional for anything involving wiring, battery terminals, gas, pressure vessels or structure.
8. Record the fault, cause and fix in the logbook and restock any spare you used.

Safety: Never repeatedly reset a breaker that keeps tripping, and never bypass a safety device.
