One of my hot water heaters (5 years old) stopped working. Pilot is out and won't restart. It has a Honeywell gas valve. It is flashing 7 times-indicating "gas control valve failure." Any ideas of what I can do short of calling a plumber?

I've seen online that some of these valves can be "reset" after a fault to see if it's truly a bad valve or just a temporary fault.

Call the number on the water heater, they usually have long arse warranties on the controls. They will most likely send you a free one. Especially if a GE sourced heater.

The basic reset sequence I know is you need to power off, and hold the two temp buttons with in 10 seconds of turning the unit back on. Then when the light starts flashing, release then press both buttons again until the light is solid. Then the gas valve resets.


sounds like the seven blinks could be your flammible vapor lockout. In any case, call the number on the heater first and see if they will send you that part, that will save you $300 in parts when you do inevitably call the plumber.


If above reset not for your unit..

quote:

you can reset the control by unplugging the blower during start up, leave unplugged for at least 5 seconds, plug back in and within 30 seconds cycle temp control from hot to low 6 times."
Although my unit has no blower (just exhaust flue), this was enough of a hint for me to figure out reset:
Switch Off. Switch On. (probably within 30 seconds of doing that you need to do following): I cycled temp from Full Hot to cold. It was around the 4th or 5th cycle of turning temp dial to Hot/Cold that it reset.

I had the same thing happen to me a few years back (flammable vapor lockout). Was still under my one year construction warranty, so when the reset wouldn't work i called the plumbed who built the house. Was a bad controller. They actually went to another hose still under construction down the road and robbed its controller to get me back up and running.

Was a State Water heater
