Question: Why Does My Hayward Pool Heater Keep Shutting Off

A dirty filter can cause low pressure and as a result, cause the heater’s pressure switch to turn OFF. A dirty filter can prevent a heater from firing and it can also cause your heater to shut off before warming the water to the desired temperature.

Why does my pool heater keep shutting off?

Overheating Pump The modern-day pool heaters are designed to shut off when pool heater running but not heating, causing overheating to the pump. This is the duty of the thermal overload switches. So if your heater keeps shutting off, you may need to look at your thermal overload switches and change the faulty ones.

How do I reset my Hayward pool heater?

The heater can be manually reset using the keypad by cycling the MODE button through “STANDBY” and back to the original operating mode (“POOL” or “SPA”).

How do you troubleshoot a Hayward pool heater?

MEASURE VOLTAGE ACROSS GAS VALVE DURING IGNITION. IF 24V, BUT VALVE DOES NOT OPEN, REPLACE GAS VALVE. MEASURE VOLTAGE ACROSS GAS VALVE DURING IGNITION.Hayward Pool Heater Troubleshooting. PROBLEM PRESENTING PROBABLE CAUSES POSSIBLE SOLUTIONS HEATER WILL NOT BRING POOL TO DESIRED TEMP WATER FLOW IS TOO LOW ADJUST BYPASS FOR MORE FLOW.

How do I test my pool heater pressure switch?

To see if the switch is working right, you can check it for voltage with a power meter or multi-meter. You can also temporarily bypass the pressure switch by using a jumper wire to make good contact with both terminals on the switch. If the switch is the problem, bypassing it should allow your heater to start running.

How do you adjust the pressure switch on a Hayward pool heater?

Turn the adjustment knob on the pressure switch clockwise, until the heater turns off, then turn the knob 1/4 turn ounter-clockwise, so that the heater turns back on. Turning the adjustment knob clockwise increases the pressure needed to close the switch.

Why does my Hayward pool heater keep turning on and on and off?

If your swimming pool heater is cycling ON and OFF, it is an early indication that the electrical connection or power supply is experiencing issues.

What does if on Hayward heater mean?

The Hayward heater LED display will show a diagnostic fault code of “IF” which stands for Ignition Failure. Undetected gas pressure problems if not investigated properly may result in unnecessary replacement and servicing of your Hayward Pool Heater.

What does F1 mean on a pool heater?

FLO, FS, F1 Make sure the pool pump is receiving enough water. Check that the pump is sending enough water to the heat pump.

How do you troubleshoot a pool heater?

How to Troubleshoot a Pool Heater Examine Error Codes. If you find that your power heater turns on but then keeps shutting off, this could indicate that you are having water pressure issues. Examine Power Sources. Check Your Outdoor Temperature Settings. The Pilot Light. Leaks. Exhaust. Rust.

How do I reset my pool heater?

Reset the circuit breaker for the pool heater. Put the system in standby using the control panel (typically accomplished by pressing and holding the Up & Down buttons) Check for an error code (if you see a code like bD or HF this could indicate a gas problem and your system will not reset until the problem is resolved).

How long do pool heaters last?

You can expect a gas or heat pump pool heater to last 8 to 11 years, with an average of 10 years. Regular usage and maintenance is key to a longer lifespan.

What does Flo mean on a pool heater?

The FLO code is indicating that the filter pump has stopped the flow of water to your heat pump. The heat pump cannot heat without water flow so it will turn itself off until the filter pump timer turns back on giving the heat pump the water flow it needs.

What causes high pressure switch trip?

The most common cause of a refrigerant high-pressure switch tripping in the wintertime is lack of airflow across the indoor coil. One of the signs of lack of airflow is a high temperature split across the indoor coil. A dirty coil will prevent proper airflow and heat transfer across a coil.

How do you adjust a flow switch?

Turn the adjustment screw clockwise to raise the flow rate required to activate the switch. Turn the adjustment screw counterclockwise to lower the flow rate required to activate the switch.

How do I clean my pool heat exchanger?

Remove the heater screws that secure the heat exchanger in place; move it to a clean surface. Apply a degreaser to the heat exchanger using a soft-tipped brush. Allow the degreaser time to loosen any soot. Wash the heat exchanger with a garden hose.

How do I reset my Hayward EcoStar pump?

To manually clear, shut off the breaker supplying the EcoStar with power for at least 1 minute, then restore power.

Why is my electric pool heater not working?

The most common cause is flow, a dirty basket, or clogged or dirty filter. A pool heater is an “open boiler” system, meaning the heater is cooled by the water flowing through the heater. All pool heaters have a pressure switch or flow switch that measures the flow rate of water pumped into the heater.

Does a Hayward pool heater need a regulator?

Almost all pool heaters have a gas pressure regulator, which is both preset and sealed to prevent accidental changes in gas pressure. Do not attempt to change or open the gas pressure regulator on the pool heater, as this may cause a gas leak or even a potential explosion.

Where is my pool temperature sensor?

The temperature sensor is typically mounted in a hole drilled into the PVC pipe and then secured with a band clamp around the pipe and sensor. Temperature sensors in other pool equipment also use 10K thermistors, including: Pentair IntelliChlor – the Harwil Q-12DST-C2 in it has an integrated 10k thermistor.

Why does my pool heater cycle on and off?

The most common cause of a heater that cycles on and off could be inadequate water flow to a dirty filter or closed valve. (See information on How to Backwash a DE Filter or Clean a Cartridge Filter).

How do I know if my flame sensor is bad?

How do I know if my furnace flame sensor is bad? Switch off the power to your furnace. Close the gas valve. Take out the mounting screw. Carefully pull out the sensor. Inspect the sensor: if the insulation is intact but appears sooty, burnt or slightly corroded, it might only require cleaning.

Where is my flame sensor?

A furnace flame sensor is a very basic part of your furnace. It’s located on the burner assembly and is just a thin metallic rod. It’s usually bent, and it sits just in front of the pilot flame inside the furnace.

How do you trick a flame sensor?

Luckily, making such a check is very easy: Take a multimeter with microamps (µA) measuring system. Keep the furnace system turned on. Connect it to the wire that is leading to the gas valve. Connect the other side of the multimeter to the sensor terminal. Take the lead away from the flame sensor.
