What Is A Pressure Switch And How Does It Work
The pressure switch on your Honeywell hot water heater works as a safety component. When the fan inside the Honeywell heater starts rotating, the pressure switch detects the activity.
It closes the circuit to ensure the proper performance of the heater. However, if the pressure switch detects any abnormality, it keeps the circuit open, resulting in the heater blinking 3 times.

Honeywell Water Heater Status Light Blinking 3 Times [Fixed]
Here, we will talk about all the reasons behind the Honeywell water heater flashing 3 times. So, let us dive deep into the details of the Honeywell issues and their solutions.
1. Weak Fan
One of the major reasons behind the Honeywell water heater light blinking 3 times is due to the weak performance of the fan. This typically occurs when the motor is faulty or the blades are clogged.
If the fan doesn’t work properly, then the pressure switch won’t be able to detect the signal. This will prevent the water heater from working and result in the light blinking 3 times.
How To Fix It
Turn off the heater and examine the fan connected to the heater. Ensure that the fan is in proper working condition.
Repair or replace the motor if it’s faulty and clean the blades properly. Turn the heater back on and ensure that the issue is resolved.
2. Faulty Pressure Switch
The faulty pressure switch is another common reason that causes the Honeywell hot water heater to blink 3 times.
If the pressure switch is malfunctioning, then the switch won’t work, preventing the circuit from closing. This will stop the heater from functioning properly and cause the light to blink 3 times.
How To Fix It
Turn the water heater off and check the pressure switch properly. Identify the issue of the pressure switch.
Repair or replace the pressure switch and make sure that it’s installed properly. Turn the heater on and check whether the heater is working properly or not.
3. Blocked Exhaust Vents
Oftentimes, the exhaust vents get blocked due to an accumulation of dirt, debris, and so on.
The air cannot pass properly through the vents due to the blockage which in turn causes the pressure switch to remain open. Thus, the Honeywell water heater blinks 3 times.
How To Fix It
Turn off the water heater and let the temperature drop down properly. Check the exhaust vents of the heater and examine the dirt accumulation there.
Clean the vents properly and allow them to air dry. Turn on the water heater and ensure proper performance.
4. Faulty Gas Valve
Another major reason behind the Honeywell status light blinking 3 times is the faulty gas valve.
When the gas valve connected to the water heater malfunctions, it prevents the gas from passing through the unit. This prevents the pressure switch from closing, thus, resulting in 3 times blinking of the hot water heater.
How To Fix It
Turn off the heater and let it cool down completely. Turn off the gas valve and examine the valve properly. Repair or replace the gas valve with a new one and install it properly. Turn the gas valve on and ensure proper performance.
5. Clogged Pipes
Air input and output of the water heater are important to ensure proper performance.
Over time, dirt, debris, and so on accumulate in the pipes preventing the pressure switch from working properly. This results in the hot water heater blinking 3 times.
How To Fix It
Turn the heater off and ensure that it’s cooled down completely. Examine the pipes properly and clean them.
Remove all traces of dirt from the pipes and dry them properly. Turn the heater back on and ensure that the lights are working properly.
FAQs:
Why Does My Honeywell Water Heater Blink?
The Honeywell water heater blinks for various reasons. Depending on the flash numbers, it indicates proper performance or problems in the heater.
How Do I Know That My Honeywell Water Heater Isn’t Working?
If the Honeywell water heater doesn’t work properly, then the water will come out cold or lukewarm. In some cases, the heater won’t turn on at all.
