SOURCE: Rheem 50 Gal Hot Water Heater will not stay lit

On the back of the gas valve (where you turn the temp up) there is a stem that actually goes into the tank that senses the temprature of the water it could be dirty or buried in sediment depending on how old the tank is, or just bad. if the tank is over 10 years old i wouldn't bother replacing the gas valve, the tank is probably not far behind. A new valve will run around $100.00 maybe a little less. You wont find it at menards or home depot in stock but they may be able to order it for you. Menards sells rheem products or try you local plumbing supply house. REMEMBER TO RELIEVE THE PRESSURE ON THE TANK BEFORE YOU WORK ON IT. IF YOU CHANGE THE VALVE DRAIN IT FIRST!

Why when I turn the hot taps on I get milky water out of the hot taps and its a new HWS Vulcan 250 lit electric single element only 3 months old


Put that water in a glass and let it sit for a couple of hours. If it clears up, it is air bubbles. The old unit most likely had mineral deposits on the elements and they insulated the water from micro heating that creates the bubble. Since the unit is new, the water is in direct contact with the heating elements and micro bubbles are forming on the elements. When you turn the hot water on, the turbulence washes the bubbles out.

The hot water temperature is not constant with the burner shutting off


You can get a sound like that when there is too much sediment in the bottom of the tank. Turn it off drain and flush it until the water runs clean.

Junkers manual gas hot water


What are you expecting to happen?

I assume the water heater and water inside it is cold (otherwise you would not be lighting it). You light the pilot. The main burner comes on and the pilot lights it. The main burner should stay on until the tank is hot, When the tank gets hot the main burner should shut off but the pilot stay on. If you draw hot water, cold water will run in and cool the tank. If yu do nothing the tank will eventually just cools off. then the main burner should come back on to reheat the tank.

Raise temp above 120


Raising temperature above 120 degrees requires service call.
Or change dip switch settings and risk voiding warranty and causing service call expense.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html#temperature

Earliest versions of Rheem tankless 2006-8 let you set temperature up to 140 degrees F using remote.
However the hotter setting caused error codes because the burner cannot keep up with both high temperature and large volume of hot water rushing through pipe. Especially in winter with cooler incoming water that must be heated more to reach temperature set point.
The burner simply cannot keep up.
So Rheem changed maximum temperature at remote control to tepid 120 degrees, which is not hot enough for folks wanting hot shower, or folks filling whirlpool tub because water in tub cools before tub fills.

Water heater burner wont light


Problem is not thermocouple:
Thermocouple should be finger-tight plus 1/4 turn
Overtightening will short thermocouple against gas control valve, and solenoid switch will not open, and no gas will reach pilot once red button is released.
Tip of thermocouple has to sit in the pilot flame.
If pilot flame will stay on, then thermocouple is good.

Problem is not solenoid switch.
The gas control valve solenoid opens and closes gas supply to gas control valve.
On mechanical gas control valve, when you push down the red button to light pilot, then you are opening the solenoid and letting gas flow into gas control valve.
When heat is applied to thermocouple, a small electric current travels to gas control valve, and this causes solenoid to stay open.
If you extinguish pilot, then no current travels to gas control, and solenoid clicks off.
You can hear it click, and this is how you test it.
However, since you are getting gas to pilot light, then the solenoid is not the problem.

This leaves 4 possible problems:
1) Bad gas control valve thermostat.
http://waterheatertimer.org/pdf/How-to-replace-water-heater-gas-valve.pdf
2) Inadequate gas pressure. Call gas company.
3) Dirty combustion parts. Clean the burner with wire brush and water.
4) Clogged air intake on FV water heaters: Rheem FV gas water heaters have glass vial that will break if combustion is slowed by clogged air intake.

1 Answer

The water heater starts to heat for about 2 to 3 mins then shuts off. Then the pilot will not even light back up for about half hour. then does same thing.


May be the gas control/thermostat, probably the safest thing to do is replace the control. Are you sure the main tube to the burner is clear of debris and the pilot tube. If they are then replacing the control should work, you can find them on the internet, write down the model no. and the serial no. and contact Rheem for a part no. or just buy it from them. Some hardware stores carry controls for different water heaters. If you cannot do this yourself, find a reliable handyman that knows plumbing. The gas control part is probably $75 and up. take care.
