Question about Hayward Pool & Spa
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.

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)

Tips for a great answer:

• 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:
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.
