The Hayward H400 pool heater is a top of the line product that is known for its quality and durability. However, even the best products can experience problems from time to time. If you are experiencing an error code on your Hayward H400 pool heater, don’t panic. In most cases, the problem can be easily fixed.
The most common Hayward H400 error codes are E02, E03, and E04. Each code corresponds to a specific problem that your heater may be experiencing.
E02 is the most common Hayward H400 error code. It indicates that there is a problem with the flow switch. The flow switch is responsible for detecting water flow and stopping the heater when the pool is drained. If the flow switch is malfunctioning, it will cause the heater to shut down.
E03 is the error code for a low water pressure situation. This can be caused by a number of things, including a clogged filter, a closed valve, or a low water level in the pool.
E04 is the error code for a high water pressure situation. This can be caused by a number of things, including a blocked line, a closed valve, or a high water level in the pool.
If you are experiencing one of these Hayward H400 error codes, there are a few things that you can do to try and fix the problem.
If you are experiencing the E02 error code, the first thing you should do is check the flow switch. Make sure that the switch is in the correct position and that there is no debris blocking the flow of water. If the switch is in the correct position and there is no debris blocking the flow of water, you may need to replace the flow switch.
If you are experiencing the E03 error code, the first thing you should do is check the filter. Make sure that the filter is clean and that there is no debris blocking the flow of water. If the filter is clean and there is no debris blocking the flow of water, you may need to replace the filter.
If you are experiencing the E04 error code, the first thing you should do is check the valves. Make sure that the valves are open and that there is no debris blocking the flow of water. If the valves are open and there is no debris blocking the flow of water, you may need to replace the valves.
If you are unable to fix the problem yourself, you may need to call a professional to help you troubleshoot the problem.

How do you clean a Hayward flame sensor?
A Hayward flame sensor is a device that is used to detect the presence of a flame in a boiler or furnace. The sensor is made up of two metal rods that are placed in the path of the flame. When the flame passes between the rods, it creates an electrical current that is detected by the sensor.
If the sensor is dirty or covered with soot, it will not be able to detect the presence of the flame. This can cause the boiler or furnace to shut down, or it may cause the furnace to run inefficiently.
The Hayward flame sensor can be cleaned with a wire brush. First, remove the sensor from the boiler or furnace. Then, use a wire brush to clean the rods. Be sure to clean the entire length of the rods, including the ends.
Once the rods are clean, reinstall the sensor and test it to make sure it is working properly.
Why does my pool heater keep shutting off?
If your pool heater is shutting off, it could be due to any number of reasons. Let’s take a look at some of the most common causes:
1. Low water temperature. If the water temperature in your pool falls below the setpoint on your pool heater, the heater will automatically turn off.
2. Clogged filters. If your pool filters are clogged, the heater will work harder than necessary to heat the water, and it will eventually shut off.
3. Low gas pressure. If the gas pressure in your pool heater falls below the setpoint, the heater will automatically turn off.
4. Dirty or corroded heat exchanger. If the heat exchanger in your pool heater is dirty or corroded, the heater will not be able to generate enough heat to keep the water warm.
5. Faulty thermostat. If the thermostat in your pool heater is faulty, it will not be able to accurately measure the water temperature, and the heater will shut off.
If your pool heater is shutting off, there are several things you can do to troubleshoot the problem:
1. Check the water temperature and make sure it is above the setpoint on your pool heater.
2. Clean the filters and make sure they are not clogged.
3. Check the gas pressure and make sure it is at the correct level.
4. Clean the heat exchanger and make sure it is not dirty or corroded.
5. Check the thermostat and make sure it is working properly.
If you are unable to troubleshoot the problem yourself, or if the problem is not resolved by following these steps, you may need to call a professional to help you diagnose and fix the issue.
How do you troubleshoot a pool heater?
If you are having trouble with your pool heater, there are a few things you can do to troubleshoot it. The first step is to check the filter and make sure it is clean. If the filter is dirty, it can cause the heater to work harder and may not work properly. You should also check the water level in the pool and make sure it is not too low. If the water level is low, the heater may not be able to generate enough heat to warm the pool.
You can also test the heater to see if it is working properly. Turn off the heater and then turn on the pump. The pump should turn on within two minutes. If the pump does not turn on, there may be a problem with the wiring or the circuit breaker.
If the pump does turn on, let it run for a few minutes and then turn off the heater. The heater should turn on and the pool should start to warm up. If the heater does not turn on, there may be a problem with the thermostat or the heating element.
