Jump out the thermostat to test the unit. If it comes on, you have your answer. If it does not come on, you will need to look at the control.

on start up the clicking noise is normal as well as knocking noise ....one important item with fan , if the fan was removed cleaned and then reinstalled with power to unit could have ruined the fan and it will have to be replaced..... Cant tell you why is wasn't firing before with no codes...other than flow sensor not working( most likey stopped with sand fragments or trash) the flow sensor detects hot water demand and ignites heater and if clogged it will not light up but doesn't give error code and the water running through hot side will be cold..... flow sensor is a turbine that detects water movement and lets heater light..... may want to get serviceman to check this out and clean turbine.... hope this helps...

How to troubleshoot and maintain a gas or electric water heater


Water heater problems normally become self-evident: A hot water faucet fails to summon hot water, you see dripping or puddles near the water heater, or the tank emits strange gurgling or popping sounds.
Though many gas utility companies will make a free house call to solve problems with a gas water heater’s burner or the gas supply to the tank, it helps to know how to solve basic outages yourself. For more difficult issues, contact a qualified local hot water heater repair person.
Typical water heater problems include a leaking tank, not enough hot water, water that is too hot, water that is not hot enough, strange noises in the tank, and discolored water. Most water heater problems are easier to diagnose and relatively easy to handle if you understand how they work. For more about this, see How a Storage Water Heater Works. Note: Leaking natural gas can be dangerous. If you smell natural gas (it smells a bit like garlic) near the water heater, shut off the pilot light, close the gas shutoff valve, and call a plumber or your gas utility company for assistance. See our information on gas leaks.
How to Flush & Drain a Water Heater
Before draining and flushing your water heater, turn off the gas or electric power (depending on whether it is a gas or electric water heater) and let the water cool a little. Close the incoming water valve and attach a hose to the drain valve to run the water into a large bucket or to a drain or the outdoors. Open the drain valve and open one hot water faucet somewhere in the house to let in air. When all water has drained from the water heater, turn the cold water valve on and off until the water from the drain runs clear. Then close the drain valve and the hot water faucet, open the cold water valve, and turn the water back on.
Water heater tips
Set the temperature control to about 150 degrees F. or lower if you have no dishwasher or if you have small children or elderly people in the home who might scald themselves. To minimize the energy it takes to heat the water, insulate your water pipes if they run a long way from your heater to your faucets. Also consider installing a point-of-use water heater. Always shut off the power to an electric water heater before working on it. Periodically check the temperature-pressure relief valve, which keeps pressure in the boiler from building up too much. Lift or lower its lever on this valve. Water should drain from the overflow pipe. Do not work on an electric water heater if there is standing water pooled on the floor near the appliance. Shut off the circuit to the water heater and call a qualified water heater repairperson.

I have a motorhome that has an LP gas hot water heater. The unit lites and you can see the flame but I have no hot water. Someone told me there is some kind of a valve that is stuck that is restricting the...


If you run hot water thru the hot side of the kitchen faucet does the water heater come on and burner run to provide hot water or does it just start then shut back off. If it starts then shuts back off I would turn thermostat up to a higher temperature. If it will not go any hotter you may need to rplace the gas valve.
Make sure your burner is clean and has a good quality flame .if not clean burner andcheck gas pressssure ti your water heater burners.
I do not know of any valve then normal so I can't help you there. Good luck Thank you.

Erratic water delivery from gas hot water heater


I can understand if it was an electric water heater doing this with a faulty thermostat, but a gas water heater with erratic heat control is very odd. I am assuming this is not a boiler, or an instantaneous or tankless water heater, correct? And you have not had any issues with the pilot going out or it shutting down? Is this an old unit? I've seen some water heaters with so much sediment in the tank, that it crackles and sputters every time the burners come on, which affect how well it heats the water and gives it a slower recovery time. What temp setting do you have the gas control set at? Maybe it's set to low? I'm curious about the burner. When it is calling for heat, have you watched the burner light up and stay lit for long periods of time? It should be a strong blue flame and there should not be any black soot build-up in the combustion chamber around it. It 's certainly a lot easier to diagnose appliance problems when you can actually see it in it's installation, as there may be some unknown factor that may be adversely affecting it. Douglas

Yes usually it is indeed the thermostat, or Thermistor, all part of the control circuit. You did not indicate what type of setup you have. I suggest you Google for a thing called a service manual. This will aid in diagnosis, and repair of your system.

Laars-lite LD 97-2000 pool heater wont burn


cycling usually begins as the result of poor water flow caised by debris in the pump, dirty filter or low water level. once you have had some cycling the heater burners and ignitor become sooted and this requires pulling the burner tray, de-sooting the burners and pilot and reassembly. unless you are very competent you may want to call a service tech. Pool heater repair is a high laibility endeavor if done improperly. During the certification class our instructor showed us several houses that were burned down from improper heater repair.

Rinnai R53 Natural Gas Tankless Water Heaters


It sounds like the Rinnai units are working correctly but you've got some plumbing problems.  Any tankless heater has a minimum water flow required to keep the burners going.  If the burners were going with very little water flowing through them to carry the heat away, the heat exchanger could overheat and fail.  The solution is generally to the electronic controls to set the desired temperature and then just use hot water.  Once you start mixing cold water in, you actually reduce the flow of hot water and the burners turn off.  If you are right near the cut off point, the burners will cycle on and off resulting in those very annoying hot-cold-hot-cold showers.  
The fact that you've got those very loud noises indicates some other sort of plumbing problem.  Hooking up two tankless units in series is much more complicated. In heavy draw situations, the second unit is asked to finish heating the water up to temperature when the first unit couldn't quite get it there. Now you're putting hot water into a heater and heating it more.  You have a lot more issues with fluctuating temperatures and pressures within the pipes which could conceivable cause these horrible noises.  Everything's got to be set up right to for things to function properly and it's easy to get something wrong.
From your description, it sounds like a better solution would have been to mount the two heaters in different places. e.g. One in the basement to serve basement and first floor faucets.  The other on the second or third floor to serve those two floors.  Since these units are direct vent (don't use inside air), they can even be mounted in a closed closet as long as the vent can get to the outside.  With this setup you avoid the complexities of a series installation and you also have a much shorter wait time (and therefore less waste) for the fixtures on the upper floors.

Assuming you have waited a couple hours and the water is still not getting hot there are too many different reasons that the tank might not be heating. Is it Gas or Electric? Is the burner on? Is the thermostat set to turn on, or set to a higher temperature? if you open the water valve at the bottom of the tank, check to see if the water is warm, cold, or hot. (POSSIBLE BURN HAZZARD BE CAREFUL so dont put your hand under the valve and open it, have it pour into a container, and then touch the water with a stick, and then touch it to your hand or some other safe way like that)
Check the simple things 1st, like if its Gas, that the gas valve was turned on, or if its electric, then then electric was turned back on etc.
More info would be needed to help you further.
Good luck
