Low water pressure through the unit, you just need to adjust your valves to supply the right pressure to the heat pump.

SOURCE: Heat pump will not start

Could be a firmware issue and require a new mother board. Unfortunately, you probably have done all you can on your own. Time to call the local HVAC service person...

SOURCE: 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.

The flow sensor within the heat pump must be clogged. not sensing any flow. clean your filters, backwash your filter. usually means low pressure.

LP (low pressure fault) is on screen.


This could be something as simple as a dirty filter. Heat pumps are notoris for pressure problems as they are very fickel. Make sure your filters are clean, then their should be a by-pass assembly on your inlet, outlet pipes for water this valve needs to be set at just the right spot to keep the water flow high enough to collect heat but not so high as to not warm enough. Setting this flow is easy enough with the unit on restrict the flow till the unit starts and wait to see that it keeps running. use a gentel hand and do this very slowley as the unit takes time to respond. But first make sure your filters are very clean and your baskets also. These are usually the culpret's when it comes to low pressure and low flow. The switch usually just tell's you that is where the problem is. If their is no corrosition or leaking at the pre. sw. more often than not it's ok and just tell's you to start looking for the problem. Good luck.

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.

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.
