Hayward heater 100id - less than a year old. When the pump is low setting (3 gpm) the heater makes a whining high pitched noise. It fires and heats but makes the noise, only when the burners click on. ON the high setting, from the pump, no noise at all. I just put in a new filter cartridge too.

    This is a pool heater. Forgot to mention. It is only months old. There definitely is a difference when the water is running trhough it at hosetting 10 gpm vs. 3gpm

  • jvalvoda Feb 01, 2010

    It's not the gas line because it does not make any noise when the water pressure rises from 3gpm to 10gpm. I am wondering if there is a diaphragm or diverter valve in the heater that is not fully opening at low water pressure. It's not a whistling type noise. It is coming from the heat exchanger. Not a clanking noise either

  • jvalvoda Feb 01, 2010

    It started about a month ago. Coincidentally or not?? Around the time the filter was getting dirty enough that the low flow water did not kick the burner on. Once I cleaned the filter and subsequently put in a new one, the burner kicks on at 3gpm. Whether that is a cause and effect - I have no idea

  • jvalvoda Feb 01, 2010

    I'll try it. It makes sense at this point as it is water flow related

This could be your gas line if you have a flex gas feed to the heater. They are normally to small and will wistel.

    Their are two things inside your water manifold that could cause noise at a low flow, one would be an internal by-pass assembly that could give you some noise. Or more likley a thermal govener that looks like a thermostat in a car and does much the same job. It slowes water from going through the heater to keep the internal temp up so you don't get condensation on the heat exchanger. This may be working better at higher pressure.

    Has this always done this or did it just start?

  • Kieran Ruppert Feb 01, 2010

    If the problem is in one of these itims this could very well be the cause. If the heater got enough pressure to start but not enough flow the excess heat could have caused the problem. Once again the thermal govoner is more likley to have problems from this. But both are inside the manifold and if you open it up it may be worthwhile to replace both while you have it open.

  • Kieran Ruppert Feb 01, 2010

    Good luck and let me know how you do with it.

Hi
It could be very high water pressure, especially if there is no thermal expansion tank. 7 years is average heater life in some areas. It is possible that there is a pinhole leak in the tank. If you don't see any evidence, the leak could be in the central flue where you won't see it. Next time it happens, check to see if the burner is on. That may rule
In/out gas as the cause. Sometimes the pilot burner can make noises, but running the water should not affect the pilot. Check if there is a little dribble coming out from the TP valve (Temperature & Pressure) on the side near the top of the tank with as pipe going down almost to the floor. You might even try touching it to see if you can feel the sound. It could be building up too much pressure in the tank due to no pressure release and too much pressure in your home. It also could be build up of deposits on the bottom of the tank. It depends on the local water conditions. A weak TP valve is easy and cheap to replace. However not much you can do after the fact about the buildup.

My 2hp hayward super pump is just out of warranty and has begun leaking. It also has a high pitched whine which comes and goes. Does that mean waters gotten into the bearing and if so can I replace it?...


Yes, water may have entered into the motor, mainly into the front motor bearing, where it washed away the lubrication. This will only make the noise louder and will need to replace the bearing. otherwise it will eventually seize and no longer work.

This reminds me of some of the High temp sensors ive replaced. I would start with checking the pumps flow to the heater. Make sure there are no abstructions and at least 35 GPM (gallons per minute) running to the heater. If your flow is too low, you will trip the high limit sensor after a short while.
This could also mean you need to clean out the heat exchanger. When an exchanger gets dirty, it blocks the flow of water, slowing it down and "super heating" itdue to the water being in contact with the exchanger for too long. This will also trip the high limit and call for service.
If both the above items check out, contact me @ adamh@newconceptchem.com and I will guide you further.

sounds like the bearings are going out on the motor. The noise will increase as they wear out more until it locks up and throws the breaker. You can have the motor rebuilt or just replace the motor. Consult a pool professional to help out with this.

I have Hayward Centurian SE 2 hp pool motor pump,around 15 years old. Just the other day it started making a loud whining noise. Is there a quick fix for this?


if its whining but still spinning, the bearings are done. If it just makes a loud noise, the capacitor could be bad or the bearings have seized.

Dryer still heats up, but it sounds like the motor is making a high pitch whining noise?


something might be hitting the blower wheel or the wheel could be cracked,remove the bottom panel,take out the lint filter and remove the duct that the filter slides into, start the dryer and check the blower wheel to see if it's that or the motor,clean out the duct and vac out the inside of dryer while you're in there,blow out the vent line,do this once a year and you'll have less problems with dryer and no fires

This sounds like a problem with impurity buildup on the coils. About once a year, More often in high mineral content water, you should clean your heater user a a cleaner that removes lime and mineral deposits. This is usuall called a descaler cleaner.

My propane heater rumbles and thumps when turned on.


Sounds like you have a 2 speed pump. The heater needs high speed to operate. The noise is due to the low water flow. The water is actually boiling in the heater. Crank up the flow and that should solve your problems.

Dishwasher Making Loud High Pitched Noise.


A loud high pitch whine while running the dishwasher means that there is something caught in the chopper assembly. To get to the chopper assembly you need to take the racks out and take the pump apart from the inside of the dishwasher. The chopper assembly looks like a metal grate with holes in it. And it might not even be stuck in the grate but somewhere in the pump area due to the water being pumped out, so the best idea is to take the whole thing apart and clean everywhere. However I do not recommend doing this unless you are completely certain you will remember where the screws and gaskets go, otherwise you risk damaging your pump or house from a leak or improper installation. You have been warned.
