Aqua pro 500 is flashing lp. We just had a new pump installed and are just trying to get pool warmed up. Pump worked fine last season. Any suggestions?thank you


LP: This code means "Low Pressure" or low pressure switch. Either the outside ambient temperature is below 50°F (38°F
for h/c units), which is too low for the heater to operate, or the unit is low on refrigerant. Once the outside temperature has risen above 60?F, and the LP code remains, call the factory for repair. https://ecoaquapro.com/wp-content/uploads/2014/06/AquaPro-Pool-Heat-Pump-Manual.pdf

Turned on my Heat Pump, kicked on for a few minutes, now it won't kick on and code said L5, now says LP. Left it alone all night, still says LP???


HOPEFULLY ITS STILL UNDER WARRANTY.
CALL HAYWARD OR GO TO HAYWARDPOOLS.COM.
THEY WILL SEND A LOCAL SERVICE REP TO COME ADJUST THE FREON LEVELS (LP).

Malfunction code tE


TE error code stands for thermistor error. You have to remove the front panel and ohm out the heating element. If you have continuity most likely it will be fine. There is a thermistor located next to the heating element that will probably need to be replaced. LG's are the only machine besides GE ref's that I have ever seen thermistors go bad on. There is probably an ohm reading you should get through the thermistor but unless you have an analog meter or a fluke most standard digitals wont read into mega-ohms. Removing the front panel is model specific. But i can tell you the spring around the front boot (drum gasket) needs to be removed and there will be some hidden screws at the bottom by the pump where the access panel is located.

Hope this helps _MJ_

I have a rome Industries Pool heat pump model 105 showing error code LP???? what does that code mean and what do I do?


I happen to work for Rome Industries and can help you out. The "LP" code on your control board represents "Low Pressure". This is referring to the refrigerant pressure within the unit. The unit is equipped with a low pressure safety switch that when activated shuts the unit down. This could be caused by a refrigeration leak, a stuck thermal expansion valve, or even a faulty pressure switch. If you live within the state of Florida contact Rome Industries and you will receive a free of charge service call including parts and labor as long as your unit is under warranty. If your outside of the state please contact your dealer to handle the claim. Have a good day.

Raypak gas pool heater with error code HL2


Do you have power to the heater?If you do then I would look for a hi limit switch to reset.It might be the pump you have to reset.
