Rheem has a tool for you to test theories like this. It is being overhauled


Yes, your element is discontinued.


Here is the one you are considering. At 1,000 watts less, it will just take a little longer to recover. Phone them, as to speak to someone in the Service Department. They will know. You know we aren't them? We just have a category here at Fixya.



Rheem Water... | Answered on Jan 19, 2021

The system I am familiar with uses a vapour pressure type thermocouple and if the pilot remains lit the thermocouple is working as it controls the gas for the pilot and the burner at the same time from the same source - if the gas control is ok and the flow isn't prevented by the thermostat then if the pilot remains alight, there should be a flow of gas and the burner should light - unless the gas jet is blocked or something else, some other type of blockage is preventing the flow of gas to the burner...

I suggest you check the gas jet and the flow of gas to it...

Rheem Water... | Answered on Dec 31, 2020

Have 2 of these Rheem units in my house. Both had this same error code within 30 days of each other. And my neighbor has 2 units as well - and guess what - 2 months after mine stopped working because of the code - so did theirs. It is not something that can be fixed. It is a manufacturer's defect - and it looks like Rheem has yet another class action on their hands (like the one for the RTG - 74 PVN). They need to do a recall to repace these units.

Rheem... | Answered on Dec 30, 2020

Not for sure what your root cause was and I know it's a little late but I just suffered this same exact scenario on the same water heater. Storms came through, power went out, power came back on and the water heater keeps blowing the 3 amp fuses now. I removed all the cables and plugged them back in one at a time. When I plugged in the Fan Motor connector the fuses blew. Installed new fuses with the connector out, the Fan Motor was putting out 150 VDC through the connector port (on main control). I pulled the control from the unit and Q1 is visible blown and disintegrated on the control board. Obvious control design issue. I've ordered a new control and will put a surge protector on the heater now when the new control comes in. Very disappointed that this was not caught in controls testing within the manufacturers facility. New control is not very cheap. Half the cost of a new Heater. Hopefully the Fan Motor survived the high voltage with the fuses blowing. I'm putting this here for anyone else that suffers the same issue on this water heater or the Richmond equivalents as they use the same control.

Rheem Tankless... | Answered on Nov 01, 2020

So you had water enter the burner combustion chamber through the access panel. That can be cleaned out, but was the gas control valve just above it on the water heater submerged under water as well? If so, do not use it or try to repair it. It is unsafe to use and the control must be replaced. Now whether or not it's worth while to replace just the gas control, depends on the age and condition of the water heater itself. Also, is this covered under your home owner's insurance policy? Damage from flooding is usually not covered in a standard policy,unless you had it added specifically. But it is covered if you had a water line break which resulted in the water damage. You should find out before you proceed with changing the control. We had the latter occur and our insurance co (State Farm) covered everything from clean-up to replacement). Hope that helps. Douglas

Which type of tankless water heater do you have? The Rheem Professional Prestige gas tankless water heater gives error 11 if the gas valve isn't fully open. See the manual here: https://s3.amazonaws.com/WebPartners/ProductDocuments/C5D97959-73D7-4482-9242-83DCE78310C8.pdf . For this water heaters, the first option to check that the gas valve is fully open. If the valve is fully open at the water heater, you may need a technician to check the regulator for your gas line. Every once in a while, I have to contact the gas technician from my local propane dealer to adjust or replace the regulator. It's time to call when the gas appliances have ignition problems due to dirt in the regulator.

On another model, https://s3.amazonaws.com/WebPartners/ProductDocuments/7E641D99-EAB1-49E9-8F8A-53AA99F8E0BE.pdf, the error 11 indicates that the unit could not ignite after 10 tries. This can result from low gas pressure (the regulator issue I noted above), a problem with the igniter (power or oxidation on the spark igniter), an issue with the gas valve wire, an issue with the flame detection sensor or the main control.

I hope this helps. Note: I've found a number of appliance repair technicians who don't handle gas line problems.

I have a code showing C7 13 the heater runs for about 2 to 3 mins then shuts off. Any suggestions?

Rheem Paloma... | Answered on Oct 17, 2020

Rheem fault code 11 - No ignition. Check to make sure there is gas to the unit and that the pressure is correct. Ensure the ignitor is operational before calling for service. Rheem fault code 16 - This is an over temperature warning which could indicate a possible clogged heat exchanger.

Rheem 50 Gallon... | Answered on Jan 22, 2020

It is unlikely to be the hot water heater causing the smell, it is more likely the input (the well water) having excess sulfur, bacteria and/or organic material

Because it sits in the tank longer, the smell accumulates. If it is a bacterial source, the hot water tank may be a breeding ground for anerobic bacteria. Draining and doing a disinfect with Hydrogen Peroxide (H2O2) is the easiest and safest step



Rheem Water... | Answered on Nov 13, 2019

I had the same problem with my Paloma a year and a half after installation...contacted Rheem customer service (800-432-8373) and they recommened a local installer in my area. The technican diagnosed the problem as the "flow control valve"; he managed to get Rheem/Paloma to cover the part under warranty...I only had to shell out the money for the install.
