Many pool owners face issues with this popular model. A well-functioning pool heater is essential for enjoying your pool year-round. When it malfunctions, it can disrupt your plans and cause frustration. This guide will help you troubleshoot common problems with the Hayward H250 pool heater.
From ignition issues to error codes, we’ll cover the basics to get your heater back on track. Understanding these issues can save you time and money, ensuring your pool stays warm and inviting. Let’s dive into the common problems and their solutions.
Common Issues
Experiencing issues with your Hayward H250 pool heater can be frustrating. These issues often disrupt your pool enjoyment. Below, we will explore common problems and how to address them.
Heater Not Turning On
A common issue with the Hayward H250 pool heater is the unit not turning on. First, check the power supply. Ensure the heater is plugged in and the breaker is not tripped. If the power supply is fine, inspect the thermostat settings. The temperature might be set too low. Adjust it to the desired temperature and see if the heater starts. Another possible cause is a faulty pressure switch. This switch ensures the pump is running before the heater activates. If the switch is defective, the heater won’t turn on. Replacing the switch usually solves the problem.
Low Heat Output
Low heat output is another common issue. This problem often stems from dirty filters. Clogged filters restrict water flow, reducing the heater’s efficiency. Clean or replace the filters regularly. Another potential cause is a malfunctioning thermostat. The thermostat might not be reading the temperature accurately. Test it and replace it if needed. Also, check for any obstructions in the heater’s gas supply. A blocked gas line can prevent the heater from reaching the desired temperature. Clear any obstructions and ensure proper gas flow.
Basic Checks
Experiencing issues with your Hayward H250 Pool Heater? Start with some basic checks. These initial steps can often resolve common problems. Let’s look at two crucial areas: the power supply and the gas supply.
Power Supply
The first step is to check the power supply. Ensure the heater is connected to a working outlet. Follow these steps:
- Verify the power cord is firmly plugged in.
- Check the circuit breaker. Make sure it hasn’t tripped.
- Inspect the power switch on the heater. Confirm it’s in the ‘on’ position.
If the power supply seems fine, but the heater still won’t turn on, consider using a multimeter. This tool checks the voltage at the outlet. It helps to ensure there is no fault with the power source.
Gas Supply
Next, check the gas supply. The heater needs a steady gas flow to operate. Here are a few steps to ensure everything is in order:
- Ensure the gas valve is open. It allows gas to flow to the heater.
- Inspect the gas line for leaks. Use a soapy water solution. Bubbles indicate a leak.
- Check the gas pressure. Confirm it matches the heater’s requirements.
If there is an issue with the gas supply, contact a professional. Gas leaks or pressure problems can be dangerous. It is best to handle them with expert help.
By following these basic checks, you can often identify and resolve simple issues with your Hayward H250 Pool Heater.
Thermostat Problems
Thermostat issues can cause your Hayward H250 pool heater to malfunction. These problems can lead to the heater not reaching the desired temperature or not turning on at all. Addressing thermostat issues promptly ensures your pool heater operates efficiently.
Incorrect Settings
The thermostat settings might be incorrect. Check the temperature setting on your pool heater. Ensure it matches your desired pool temperature. Sometimes, the thermostat gets accidentally reset. Make sure the heater is set to the correct mode: pool or spa.
Thermostat Malfunction
A malfunctioning thermostat can also cause problems. If the heater does not turn on, the thermostat might be faulty. Test the thermostat using a multimeter. Replace the thermostat if it does not show the correct readings. Check for loose connections or damaged wires. Fix any visible issues to restore proper function.

Pilot Light Issues
The Hayward H250 Pool Heater is a reliable choice for many pool owners. Yet, like any equipment, it can face problems. One common issue is with the pilot light. This section will guide you through troubleshooting pilot light problems.
Pilot Light Won’t Ignite
If the pilot light of your Hayward H250 won’t ignite, there could be several reasons. Firstly, check if there is gas supply. Without gas, the pilot light cannot ignite.
Next, inspect the pilot orifice. It might be clogged, preventing gas flow. Cleaning the orifice can solve this. Here are the steps:
- Turn off the gas supply.
- Remove the pilot assembly.
- Clean the orifice using a small brush.
- Reassemble the parts and turn the gas back on.
If the pilot light still won’t ignite, the thermocouple might be faulty. The thermocouple detects the pilot flame. If it’s broken, it will cut off the gas supply. Replacing the thermocouple is often needed.
Pilot Light Keeps Going Out
The pilot light going out can be frustrating. Several factors might be causing this issue.
A weak gas supply could be a reason. Ensure the gas valve is fully open. Check for any leaks or obstructions in the gas line.
The thermocouple could also be the culprit. If it is not properly aligned or damaged, it will shut off the gas supply. Ensure the thermocouple tip is in the flame. Replace it if necessary.
Another cause could be a draft. If your pool heater is in a windy area, the pilot light might blow out. Shield the heater from direct wind to prevent this.
| Issue | Possible Solution |
|---|---|
| Pilot Light Won’t Ignite | Check gas supply, clean pilot orifice, replace thermocouple. |
| Pilot Light Keeps Going Out | Ensure gas supply, check thermocouple, shield from drafts. |
Troubleshooting the pilot light issues in your Hayward H250 Pool Heater can be simple. Follow these steps to identify and fix the problem.
Filter And Pump Concerns
The Hayward H250 Pool Heater is a reliable tool for keeping pool water warm. Filter and pump concerns can disrupt its operation. Proper maintenance of these components ensures efficient heating. Below are common issues related to the filter and pump.
Clogged Filter
A clogged filter can limit water flow to the heater. This can cause the heater to shut down. Regular cleaning helps prevent this issue. Here are some signs of a clogged filter:
- Reduced water flow
- Increased pressure on the filter gauge
- Heater not reaching desired temperature
To clean your filter, follow these steps:
- Turn off the pump.
- Release the air from the filter tank.
- Open the filter housing and remove the filter.
- Rinse the filter thoroughly with a garden hose.
- Reassemble the filter and restart the pump.
Pump Malfunction
A malfunctioning pump can also affect the heater’s performance. The pump ensures water circulates through the heater. Look for these signs of pump issues:
- Unusual noises
- Water leaks around the pump
- Low water pressure
If you suspect a pump malfunction, inspect the following:
| Component | What to Check |
|---|---|
| Impeller | Debris or damage |
| Seal | Leaks or wear |
| Motor | Strange sounds or overheating |
Fixing these issues can restore the heater’s function. Regular maintenance prevents many problems. Always ensure your pool pump and filter are in good condition. This will help your Hayward H250 Pool Heater run smoothly.
