Question about Water Heaters
The burner comes on when it's supposed to and heats the water but must not heat it completely because the hot water runs out too soon. Any suggestions?
1) Thermostat may be bad, or out of calibration. Set temperature higher, and/or troubleshoot by type of gas control.
Copy following link to troubleshoot by type of gas control valve:
2) Dip tube broken
3) Water leak running hot water out of tank.
Turn off all taps and put ear against pipe listening for water leak.

Unless your AO is a high recover it will take a while for it to fill up with the water that you have used then reheat the water in the tank.

If it is a new water heater it might be that the water supplies are crossed. The cold water should be installed on the right hand side of the tank or on the bottom if your tank hooks up on the side. If its an older water heater the dip tube may have broken off. This is a tube that runs from the top of your water heater on the cold side to the lower portion of the tank.It puts the cold water in the bottom of the heater which pushes the hot water to the top.To change the dip tube out you must disconnect the cold water supply from the 3/4 inch nipple at the top of the tank. Then with a pipe wrench unscrew the nipple from the tank it will have the remainder of the tube on it.You can get a replacement dip tube at a plumming supply. Installation is opposite of removal. If this is your problem I suggest you get a new water heater .Usually its caused from minnerals in the water or buy two dissimiler metals being connected together in the water piping system causing corrosion Your water heater will probably fail in the near future.

Usually this type of fault is down to poor water flow. Basically you are asking the unit to work at a level below it's minimum output. Easy thing to try is to check any filters or water flow limiters in your tapware. Usually these are in the nozzle of the tap. I often take these out. The inifinty reduces water flow anyway and there is no reason to have water limiters. Try turning on two taps at once. If this stops the fault then you definately need to increase your water flow. Make sure the mains water is turned on full. Aslo you can check the cold water filter on the infinity. It's just above the cold water isolation tap (middle pipe as you look at it), turn that off first, the filter is a round plastic nut, unscreww it and clean the filter. Reconnect, turn you mains water back on.
There are other faults but this is by far the most common.

Hello. I see this all the time with these Whirlpool units. Do this:
Make sure that the end of the thermocouple is over the pilot light. The therocouple needed to be pushed farther thru the hole in the bracket.
That may solve your problem, I hope it does.
That said, if this is a new unit, seriously consider returning it. IF it is not new and the suggestion above does not solve the problem replace the thermocouple. IF that does not solve it, replace the gas valve. Joe
Thanks for choosing Fixya!
