SOURCE: water leak at top rheem 21v40s-2

you need to replace the water heater, the tank is cracked and under pressure so it is forcing the water to the nearest opening

SOURCE: I am getting alternate C7 and 76 code as unit

called Rheem and after giving them the info they are shipping out a replacement board which I can install, hopefully today..to overcome the hot water problem for the short term I disconnected the remote wires at the heater which lets the heater keep producing hot water albeit without the remote...I will keep the old board as backup in case this happens again as there seems to be problems with the PCB

Tempra plus not heating all water
This issue may be caused by several factors, including a malfunctioning or improperly sized water heater, clogged pipes, or a malfunctioning thermostatic mixing valve. Here are some steps you can take to troubleshoot the issue:
  1. Check the size of your water heater: If your water heater is too small for your home's needs, it may not be able to supply enough hot water to all areas of your home. Consider upgrading to a larger water heater.
  2. Check for clogged pipes: If your hot water pipes are clogged with mineral buildup or debris, water flow may be restricted, causing reduced hot water supply. Have a plumber inspect your pipes and clean them if necessary.
  3. Check the thermostatic mixing valve: If your home is equipped with a thermostatic mixing valve, it may be malfunctioning and causing the issue. Have a plumber inspect and replace the valve if necessary.
  4. Check for leaks: If there are any leaks in your hot water pipes, the water pressure may be reduced, causing reduced hot water supply. Have a plumber inspect your pipes and repair any leaks.
  5. Adjust the temperature settings: Make sure the temperature settings on your water heater are properly set. If the temperature is set too low, you may not be getting enough hot water.
If these steps do not resolve the issue, it is recommended to contact a licensed plumber to inspect and repair your hot water system.

Gas ignites flame but water is not getting hot
You have gas water heater with working burner.
But not getting hot water at faucet?

1) Bad faucet cartridge. Test for crossover. Copy following link:
http://waterheatertimer.org/Crossover.html


2) Is there hot water inside the tank? Open drain valve and check for hot water.

3) Drips and leaks: Turn off all taps and put ear against pipe and listen for water leak.
Water leak can run all the hot out of tank.

Ask the plumber who did the mods. to come a check that he hasn't crossed a hot/cold pipe. Really sounds like he has, this would cause hot water to mix with cold. Is the water hotter further away from where he did his work? This would be a clue. Easy way to check is to turn off the water to the hot water system, should be a valve on the middle pipe going in to the heater. This should turn off all water to all your hot taps. If you still have water at any hot tap or shower then the pipes have been crossed.

The water coming out of my faucets, washing machine, shower, etc. is not getting hot.
Your heater is on? Do you regularly drain off sediment?

Have you contunity tested your elements (power off)? Volt tested the same (power on)?

Has anyone fooled with the thermostat?

There is the possibility the dip tube (cold water going in) has broken off and instead of sending the cold water to the bottom, the cold goes straight from the cold water entrance pipe to the hot water exit pipe. Normally, one would expect cold water to sink and hot water to be on the top but, when you are drawing water off the top, with a broken dip tube, the water travels the shortest distance required, thus, your luke warm water.

I hope you can find your trouble by following one of these hints.

Thanks

No hot water
if the leak is behind the handle take the handle off and tightn the packing nut, do not over tighten, as far as luke warm water is this with just one facucet on, they way these tankless water heaters work they are by gpm, gallons per min, if you have more gallons of water going thru the unit then it is designed for then it won't get hot, if your water pressure is to high going thru it will push it to fast thru the unit and won't get hot, your house pressure should be no higher then 75lbs no lower then 65lbs
