    Mine too, It kind of sounds like gym shoes in the dryer type of sound, just softer. The burners will burn for like 10 minutes but then shut off and not come back on without turning the unit all the way off and back on. The filter is clean and I checked as best I could for anything obstructing flow.

I recently bought a fisher and paykel front loader washing machine and since it was installed it has created loud banging noises in my water pipes. Do you have any idea how I could fix this?


If you're willing to do plumbing work yourself, these and more will show you what to do.

Otherwise, a plumber will be needed to bring an end to the water hammer you are experiencing by installing an air dampener as shown below - kind of like a shock absorber on your car but in this case, the backlash of pressure is softened or eliminated by it or something similar.

Basically what's happening is the water valves are shutting off the water flow so fast, the water flow ends up vibrating the pipes and they bang against what they are next to.

Odds are you were experiencing it before but it wasn't bad enough to be noticed - I installed a set at my water heater and another set right before the water connections for the washer.

Why is it always Rheem problems?
Every water heater problem is Rheem.
And Rheem doesn't post any service manuals, like the other two big manufacturers, AO Smith-American, and Bradford White.

Copy following link for troubleshoot by gas control valve.

When the burners ignite, within one minute it starts making a loud banging noise and then the HS code comes on and it shuts down. the noise continues for about 15 to 30 seconds after the burners shut...


This sounds like a low water flow situation. The heater is telling you that the high limit sensor is curring heater operation. The noises are the heat exchangers boiling the water either due to a blockage in the exchanger , a bad mixing vlve, or most likely poor water flow. This is tough to troubleshoot through a posting like this, but 1st thing is 1st. Check your water flow and make sure it is minimum 50 Gallons per minute.

No water comes out of the hot side of my shower or bathtub


Hello,

Based on gas prices, often gas hot water heaters can be a more cost-effective option than electric models and preferred by many homeowners. However, gas hot water heater models can have their own set of problems that differ from electric versions. You will not find it difficult to perform some basic troubleshooting to resolve an issue with a gas hot water heater.

Instructions

  1. 1 Determine if the gas supply has been shut off. No gas will cause the hot water heater to stop producing hot water. Turning the gas supply back on should be your first troubleshooting technique.
  2. 2 Check the pilot light. If you are experiencing no hot water, the pilot light of your gas hot water heater may have distinguished. Turn off the gas source and place a match over the pilot light tube to relight it.
  3. 3 Adjust the thermostat of your hot water heater. If you find that the hot water runs out quickly or does not get hot enough, you may need to set the temperature of the gas hot water heater higher. Typically, set the dial between the medium and hot setting for adequate hot water.
  4. 4 Inspect the gas hot water heater. The burner orifice and flue can both become clogged on a hot water heater. Turn off the gas and use a wire brush to clean out any debris that may have become lodged in these sections.
  5. 5 Ensure that all the burner access covers are in place. If the pilot light will not stay lit, it could be due to exposure to drafts.
  6. 6 Flush the tank. Certain deposits can build up over time when using a gas hot water heater which can cause the tank to produce a banging noise. To flush it, turn the heater off and open the pressure relief valve and drain valve on the water heater. Use a hose to flush water through the system until the hose runs clear.

Thanks.

We have a Surburban 10 gallon hot water tank in our RV. Today it started making popping noises. The burner keeps back firing and making loud popping/banging noises.


The burner tube is restricted. Try blowing the tube out with compressed air or cleaning the tube out with a small wire.

The heater makes a banging sound after the burners


What you have is a water flow problem. The water should be going through the heater but it is by-passing it. The water inside the heater is boiling and trying to expand as steam that makes the banging sound. Their is a internal by pass in the water manifold on the side of the heater. If you take this apart you will find a disc on a spring contraption, if it is stuck open the water goes past the heater but still has pressure to kick the pressure switch and fire the heater. Either clean or replace this assembly. The other thing to check for is an external by-pass. This will be a gate valve bridging the inlet and outlet pipes. If you have one of these it should be 80-90% closed or the water goes through it and creates the same problem. This is not on all systems so don't be alarmed if you don't find it. Good luck.

My water heater have countinous loud sound?


There are several different things the sound could be. If it is a popping noise it could be from the sediment inside the water heater as it is heating. It could also be noise(bang) from the water pipes having excessive pressure. If the water heater is gas it could be the noise from the burner when in operation or gas regulator vibration. Need a better description of the noise to be more helpful.

High pressure, and heater noise


I am not sure if you have solved this issue, or not, but if the PSI on the gauge is high then the problem may not be the heater. When you have the system turned on, and the PSI is reading higher than normal, just the flow of water coming out your return lines. If the flow is normal, like when you clean your filter, then see if you have a way to re-route the water so it bypasses the heater. If the PSI on gauge drops, then the issue is in the heater.

If the flow of water is slower than normal, with the PSI reading high, then you have a blockage somewhere in the system. It could be something simple like removing debris from skimmer and pump backets, to time to backwash, or clean, the filter.

If the flow of water is really hard and fast, with the PSI high as well, then you have too much water going through the system and need to slow it down.
