I also called 888 437 8340 and they sent the switch right out. Very helpful phone rep. The company is called Empire Fulfillment.

SOURCE: LP (low pressure fault) is on screen.

Low pressure is usually a dirty filter ob basket. If you have a by-pass on the plumbing you can shut this down a little to get more flow through the heater. Or you may have a clog in your pump impeller. Hope this helps.

I had the same problem with my Paloma a year and a half after installation...contacted Rheem\Paloma\Richman customer service (800-432-8373) and they recommened a local installer in my area. The technican diagnosed the problem as the "flow control valve"; he managed to get Rheem/Paloma to cover the part under warranty...I only had to shell out the money for the install.

SOURCE: My water pump stops and starts. the contacts on

A lot of these pumps do have automatic thermal switches built into the motor end cap, Double check that its being fed the name plate voltage and that the voltage doesn't drop when the pump is running (which would indicate a loose or bad connection or just undersized wire in the circuit)

How do I adjust the pressure switch on my hayward h250 heater


The purpose of the pressure switch is to verify the pool pump is operating properly and water pressure is present in the heating chamber. When water pressure is not present, the heater control system is designed to not allow initiation of flame. The pressure switch is preset at the factory for deck level installations. When the heater is located below the level of the spa or pool, the pressure switch may require an adjustment to compensate for the no-flow static head.

CAUTION: The Hayward Pool Heater is essentially a furnace. A trained technician should be consulted to repair it. DO NOT OPERATE the Hayward Pool Heater without a properly functioning and calibrated water pressure switch. The pressure switch adjustment requires both the pool pump and the heater be operational. As a result, extreme caution should be used during this procedure since sources of energy can not be isolated during the procedure.

The following procedure is recommended to calibrate the pressure switch.

1. The water pressure switch is located behind the front service panel. The pressure switch is typically on the left side, above the burners.
2. Be sure the water filter is clean before making the adjustment.
3. With the pump and heater system switch on, carefully turn the pressure switch adjustment dial clockwise, until a click is heard from the gas valve.
4. Turn the adjustment dial counterclockwise 1/4 turn.
5. Turn the pump off and on several times. The heater should shut off immediately when the pump is shut off. If the heater fails to shut down when the pump is off, repeat the steps above until the pressure switch is properly adjusted.
6. If the adjustment process fails to produce proper results the pressure switch should be replaced.

Hayward heat pro error code HI


Low water flow, its heating up to high and doesn't want to melt itself down, sounds like a pressure switch problem or corrosion build up.

Heater has power but flashes code L.P


• The low-pressure switch senses the refrigerant pressure in the sealed refrigeration system to protect

against certain conditions that could be detrimental to compressor life. The switch turns the heat

pump off in the event of loss of refrigerant, fan motor failure, evaporator freeze-up, or airflow

blockage. The heat pump will automatically reset the switch after the system pressure rises to the
normal operating pressure. The display will show "LP", if this switch is tripped.

For more info, look at page 7 on this manual:

http://www.hayward-pool.com/pdf/manuals/Manual280.pdf

Either you need to defrost the coils, clean the air-flow chamber, get a new air-flow switch or you are running low on refridgerant.

Our Hayward gas heater keeps giving us a H5 error code and then shuts off. What does this mean?


Could the Error code be HS? That is high temperature limit. Perhaps you' don't have enough flow, allowing the heater to heat the water to a temperature higher, than the thermostat setting. Make sure your bypass valve is closed, allowing full flow through the heater. Check your filter pressure differential , and skimmer baskets.
You didn't give your model number, and there are many models. You can go the Hayward website below and select your exact model number and download the manual. The manual will explain each error code.

Hayward pool heater - p5 code


The code is "PS" for Pressure Switch and means there is insufficient pressure to operate (low flow) or the switch itself is bad.
