Got A Honeywell Water Heater With 4 Flashes? Here’s How To Reset It Fast!

If your Honeywell water heater is flashing four times, it indicates an issue that requires immediate attention. This blog post will provide a comprehensive guide on how to reset your Honeywell water heater 4 flashes and resolve the underlying problem.

Understanding the 4 Flashes

The 4 flashes on your Honeywell water heater signify a fault code that points to a specific issue. It typically indicates a problem with the gas control valve or the flame sensor.

Troubleshooting the 4 Flashes

Before resetting your water heater, it’s essential to troubleshoot the issue to identify the root cause. Here are some common reasons for the 4 flashes:

• Faulty gas control valve: The gas control valve regulates the flow of gas to the burner. If it malfunctions, it can lead to insufficient gas supply and ignition failure.
• Dirty flame sensor: The flame sensor detects the presence of a flame and sends a signal to the control board. If the sensor is dirty or obstructed, it can fail to detect the flame and trigger the 4 flashes.
• Ignition failure: The ignition system is responsible for creating a spark to ignite the gas. If the igniter is malfunctioning or there’s a problem with the spark plug, it can result in ignition failure.

Steps to Reset Honeywell Water Heater 4 Flashes

Once you’ve identified the potential cause, follow these steps to reset your Honeywell water heater:

1. Turn off the gas supply: Locate the gas shut-off valve near the water heater and turn it to the “off” position.
2. Turn off the electrical power: Switch off the circuit breaker or fuse that powers the water heater.
3. Wait 5 minutes: This allows the water heater to cool down and discharge any residual electrical energy.
4. Turn on the electrical power: Restore power to the water heater.
5. Turn on the gas supply: Slowly open the gas shut-off valve.
6. Relight the pilot light: If your water heater has a pilot light, follow the manufacturer’s instructions to relight it.
7. Reset the control board: Locate the reset button on the control board. Press and hold the button for 10-15 seconds, or until the LED lights stop flashing.

Additional Tips

• If the 4 flashes persist after resetting, contact a qualified technician for further diagnosis and repair.
• Regularly inspect and clean the flame sensor to prevent dirt buildup.
• Replace the gas control valve or igniter if necessary.
• Ensure that the water heater is properly ventilated and has adequate air supply.
