Error code on a Haier water heater — is it urgent?
Codes usually point to an ignition fault, a sensor fault, or a safety sensor that has shut the burner down. If anyone smells gas, everyone leaves the home now, leaves every switch as it is, and calls the gas utility from outside. Otherwise, photograph the display, the controls and the base of the tank before anyone resets anything, and use the power switch or the gas control only as the label on the tank directs. Codes that name a leak, a flame or an ignition fault, and any code with water at the base, move this up; the Triage Profile reads the panel and everything else in the photo.

In the next five minutes
Safe first steps, before the call. Nothing here needs a tool.
If you smell gas, a carbon monoxide alarm sounds, or anyone feels dizzy or sick: don’t touch any switch or plug, leave and get everyone out, then call 911 or the gas company from outside.
No gas smell? Take a photo of the code or flashing light, if you can see it without opening anything, then turn the water heater’s gas control knob to OFF if it’s gas, or switch off its breaker if it’s electric.
If you can read its label without moving it, note the brand and model number for the call.

Usually not an emergency — the code is the appliance reporting a fault it detected. Note the code, then turn it off at the breaker for a minute and back on. If the code returns with a burning smell, smoke or a leak, leave it off and call a pro.
