Honeywell Hot Water Heater Status Light Blinking: What the Code Means

Knowing your Honeywell hot water heater status light blinking can help you determine whether your heater is acting up or running normally. The different water heater has their own mechanism and operational specialties.

For Honeywell, however, the status light blinking can notify you whether it’s normal. Keep in mind, though, that the light blinking is quite normal. That’s how the heater is supposed to run and work. But pay attention to how many it should blink.

Honeywell Hot Water Heater Status Light Blinking

Understanding the Honeywell hot water heater status light code is crucial for diagnosing your unit’s condition. A normal functioning heater will have the status light blink once every three seconds, indicating everything is in order.

This blinking pattern serves as a reassuring signal that your water heater, including its gas supply and other components, is operating smoothly.

The normal heater should have the status light blinking once within 3 seconds. If you see this, you have nothing to worry about because your unit runs normally and well. The Honeywell heater should flash the blinking light once in three seconds, functioning fine.

Different Blinks, Different Problems

However, there are some possible issues when your Honeywell heater blinks several times consecutively every three seconds. You can tell the possible issues depending on how many blinks or flashes.

For instance, if the heater blinks two times every three seconds, it may mean that the main valve isn’t turned on or there is a low thermopile voltage. If the unit blinks 3 times every three seconds, it may likely mean that it experiences blocked exhaust piping, a (bad) draft pressure switch, or a clog within the condensate drainage system.

You should consult your manual to find out what’s wrong. It’s also possible to contact the manufacturer through customer service. But if you want the fastest result, contact the certified and skilled professional in your area to get help.

Honeywell Hot Water Heater Status Light Blinking 7 Times

When the Honeywell water heater status light blinks 7 times in succession, it often points to an electronics failure, potentially within the gas control valve. Before considering a replacement, it’s advisable to try simpler fixes, such as cleaning the burner or replacing the thermopile.

Ensure the gas supply is not obstructed and the knob is set to the pilot position before depressing the piezo igniter button. If these steps don’t resolve the issue, replacing the gas control valve may be time.

In most cases, the status light blinks when something is wrong with the gas control valve. You should be able to reset the blinking situation by replacing the (gas) valve or repairing the electric problems.

You should:

  • Check the wire connection of the heater (each one of them). It would be even better to hire a professional and certified electrician to ensure.
  • In the event the wiring is okay, check the gas control valve.

Honeywell Water Heater Status Light Blinking White

If your heater has a white blinking light, it’s most likely that the unit is in delay mode. Wait for around 5 minutes. Afterward, it should be on cycle again.

However, if the cycle doesn’t happen, then it’s most likely that your heater will experience bigger problems, and you need to fix them right away. It’s always better to hire and consult a certified professional to find and deal with the core issue.

Resetting the Heater

It’s not difficult to reset the Honeywell heater. Consult your manual to relight the pilot. Once it happens, maneuver the control knob to the position ‘Very Hot’ and wait for 10 seconds. Afterward, turn the knob to ‘Hot’ and then wait for another 10 seconds.

Then, turn the knob to position ‘Pilot’ for 10 seconds more. After doing all of these steps, turn the knob to the temperature setting that you want. It should successfully reset your unit.
