Question about Hayward Heatpro 100,000 Digi. Thermostat Heat Pump

1 Answer

Frost all around outside unit coils

Hayward digital heatpump purchased new 2 years ago, has white chalky build-up on outside coils (when not in use). When i tried to heat spa, I noticed icy frost forming all around unit ( &inside on copper), which caused unit to stop working properly. I sprayed the coils with garden hose water to melt, which caused normal operation to resume. Is there any thing I can do, besides service call?

Well Its a little complicated and unless you understand the heat pump /refrigeration cycle and the need for defrost and how the defrost is limited and initiated, well Id say yep...you need a pro.

About the only thing I can suggest you check is the initiate termination thermostat (assuming your Heat pump works with one of these). It will be identified by 2 wires going to it and it will be clamped on the line (Not brazed on or screwed on). Now there will also be a reversing valve which has 4 tubes going to it and 2 wires. and it could have high, low, pressure switches that have 2 wires. This thermostat is usually mounted 1/3 to 2/3 way down on the coil and is suppose to be mounted on the "U - Bend" of the out door coil tubing. It usually resembles a pancake and will have a wire or metal clip that holds it securely on the coil U bend. Make sure it hasn't fallen off or come loose. This can cause your heat pump to miss its required defrost.

You can try this also. Some defrost timer boards have a set of "test pins" you put them together with a screwdriver or a piece of wire for a few seconds to initiate a defrost. It defeats the time logic in the board It should go on into defrost and stay in until the coil is cleared of frost and or about 10 minutes which ever comes first. If it comes out right away it may be the termination switch I talked about above. It could also be the board. To check out the thermostat locate the 2 wires going to it from the board. pull them off the board and retry it. Sill goes right out of defrost then jumper the 2 wires together and try it again. If it still comes out this time it most likely the board. If it stays in defrost either time when removing the wires or jumping the wires its the thermostat.

Hope this helps you. If so please rate me as high as you can. Thank you for using fixya and good luck.
Hope this helps you

I installed a complete hayward filter with a new multiport valve. i can see DE in my pool. what would cause this? Thanks for your help.


If these Hayward pool filters are leaking DE back into the pool, there are a couple things that you will want to check. Check for loose bolts on tube nest plates and tighten them if necessary. Make sure that you don't have a worn or loose fitting diaphragm gasket and that there are no rips and holes in it. Replace the gasket if any of these is the problem. Check for openings or tears in one or more Flex-
Tubes and replace them if necessary.

un-screw the entire top valve unit. I would duct tape over the top of the riser pipe at the top.You do not want to get any sand inside that pipe. Turn upside downand rinse out completely. Add new sand remove duct tape and replace top valve unit

Torpedo pump...I have one when I plug it in...it trips breaker


I had the exact same issue. I left mine out for the winter and when I plug it in, the breaker trips. My warranty was up so my friend took it apart. The seal had broken alowing water to leak into the bottom the pump where the wires connect to top of motor. This is supposed to be water free and is protected by several seals.

I am currenlty trying to put sealant where the cord goes into unit to stop water from going in. I will let you know how that works.

One tip my friend recommeded is to make sure there is no stress on the cord as it appears this seal is weak and and kind of stress will break it. hope this helps -- Rob

Hayward Vari-Flow valve SP710X making cavitation noise w pump on.


These valves will get stiff with time and grit and sand will get into the shaft of the valve and make it hard to turn. As far as the noise, the valve is probally an 1 1/2" valve. The volocity of the water through the valve will cause cavation and this noise. When you get to the point where you need a new valve you can fix this by using a 2" valve.

I would answer that you would need two 120hp motorized pumps with control panels and an 18hp jockey pump with control panels, but that is only a guess and is most likely way wrong. I am definitely no expert in this area. Best wishes.

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.

Hayward Heat Pro Electric won't stay running


from the Hayward support site....

Why is my pump cutting off and on every 5-10 seconds?
  • Hayward motors are factory wired for 240 volts unless the motor is 120 volts ONLY. Check the voltage of the incoming supply power and ensure the motor is wired or can be wired for this voltage (data plate on motor will help provide voltage and wiring information). Also check for loose or badly connected wires. Contact a certified electrician for repair.
