Can u tell me age of model#81V30D serial#R1094B17935

I can't find any information on that MODEL you listed in your question. It's sort of like the Rheem Air Handler models but notthing comes back. In any case you will NEED the SERIAL number, as that will tell you all you need to know about it. If you can't decipher SN, call RHEEM and they can give you the info on that unit. Sorry I could not be of more help.

call manufacturer

Reliance makes gas and electric water heaters.
http://www.reliancewaterheaters.com/

Best way to start is to look at label on side of tank.
Label has serial number, model number, plus it will say if heater is gas or electric.
Reliance water heater age is shown in serial number: first digit is letter, second two digits are numbers: for example numbers 02 would be the year 2002.
If water heater is 8-12 years old, it might be time to consider new tank.

Gas water heater has 3 inch metal flue pipe coming out of top of tank.
Gas pilot is probably off.
Relight pilot light: Most gas water heaters today have instructions on side of tank just above gas valve that say how to relight pilot light. Instructions vary by model.
If you have gas water heater that is older, it might be easier to call a plumber.

Electric water heater has panels on front.
Open top panel and push in red reset button.
If you have electric water heater of any age, you can usually fix it yourself same day:

The label would also say if water heater is gas of electric.
That would be helpful information that could lead to troubleshooting.
Serial number tells us water heater was made on Nov 1998, which tells us the manual will not be on the Rheem website.

So if you have electric water heater, and no hot water.
There can be 4 causes.
1) Circuit breaker is not delivering 240 to water heater. Test top two screws on upper thermostat to see if tank has 240V.
2) ECO red reset button is tripped. Open top cover on tank and push reset button.
3) Upper thermostat is bad. Replace thermostat.

Hi ,

Can you please tell me the model of the vaillant, and the approx age?

I can solve this problem

I await your reply

Thanks

Steve :)

Adjust each thermostat (one under the lower front cover, one under the upper front cover) at the same indication (thermostats may not have degree marks but warm, hot, very hot or A, B, C). Turning the screw clockwise is hotter. For safety sake, turn off the circuit breaker for the water heater at the house electric panel before removing thermostat covers.
