I have a rheem vulcan 160 solar water heating system but the red light flashes "attention" when it is sunny. What does this mean? No manual was provided with the house!

This means the solenoid to the modulating gas valve is sharing a fault. You will need to inspect the wiring to the solenoid to make sure it's ok. You can ohm out the solenoid to make sure it's not open. If it is, you will need to replace it.

Green active lights on but not red standby and no hot water


If tankless computer is less than 5 years old, then call Rheem for local technician qualified to work on this type of computer that heats water.

If tankless is older than 5 years, then replace with tank-type electric water heater for $285 from Lowes.

Avoid Rheem, Richmond, Palmoa, GE water heating products since this company does not post service manuals.

Choose AO Smith, American, State, craftmaster, Whirlpool etc.

How long will it take Rheem solar hot water to heat up


read manual:
http://www.rheem.com.au/Assets/1294/1/Rheemsolarlolineelectric511series.pdf
Usually electric element heats about 20 gallons per hour.
It appears the element is controlled by thermostat and automatically kicks ON when tank falls below thermostat set point..
This will be handy since element will continually heat the circulating water when outside temperatures turn cool... of course it will also be wasteful if thermostat is set high.

Rheem power vent 2 flashes red led twice


Copy following link to identify gas control valve and download error code information by type of gas control, and possible service manual.
http://waterheatertimer.org/How-to-troubleshoot-gas-water-heater.html#intellivent

If you have Honeywell gas control, then 2 flashes with three second interval can mean pressure switch has failed. And or related issues.

Scroll up on same page to find pressure switch heading among the troubleshoot links.
Or use Ctrl+F find feature on browser, and word search page for 'pressure'
Same page also has Rheem parts list 2010 so you can locate exact part number using model number that shows on label on side of tank.

Rheem does not post service manuals, but other companies do, and they can apply to Rheem (except for the FV system, which varies by manufacturer)

Best that you save product manual when possible because it will have important information including, parts warranty, error codes and parts list. Plus routine recommended maintenance that can prevent outages and error codes

Rheem rte13 standby (green) light not on


You might have crossover problem caused by bad faucet cartridge.
http://waterheatertimer.org/Crossover.html

The green standby light should come on when 240Volt power is applied. Page 6 manual.
Both red lights should come on when tankless is activated. Page 6 manual

RTE 13 requires 60 amp breaker and 6 gauge wire
http://waterheatertimer.org/How-to-wire-Tankless-electric-water-heater.html
http://waterheatertimer.org/pdf/Rheem-TanklessElectricUC_AP15447.pdf

Factory temperature setting is usually default 120 degrees.
Adjust temps page 11 manual
Thermostat calibration is always approximate.
120 degrees is not hot enough to burn the skin.
Exceptionally cold incoming water temperature can cause tankless not to heat enough hot water: install tempering tank to preheat water to room temperature.
Tankless cannot be exposed to more than 11 grains hardness in water. Delime tankless yearly, clean water filter monthly, do not install low-flow restrictions or conserve water since the flow rate must remain high for tankless to activate.
Rheem does not post service manuals for their tankless water heaters.

I am getting a C2 11 code on my eco sense tankless water heater. There is also a flashing 24, any ideas? Thanks


Multiple error codes can mean PC board failure.
C2 11 is no ignition.
Error 24 is malfunction of operational switch: "press max or mim button on PC board, or replace PC board." On some models, max and mim button can be located just above dip switches, and rotates with screwdriver. See diagram in manual.

Before calling service technician, open following links for troubleshoot resources including error codes, Rheem chat, and possible manual.

Rheem, Richmond, Ruud, and Paloma are all the same manufacturer. After about 9 months, my tankless RTG-74PVN started giving me error code 11 and cold water!. I fixed it by cleaning the burner, as shown in this video:

Remote is flashing C8 and 76, alternating. I turn the unit off, then back on, and I get hot water for about 10 seconds, then it goes cold and the same error message occurs. Unit is Rheem Main Remote...


Before calling service technician, open following links for Rheem tankless resources including error codes and Rheem chat.
Disconnect wires from remote to see if system stabilizes. Unit will heat to default temperature without remote.

Error codes are considered start-point for troubleshooting.
C8 76 can mean PC board failure.
76 can mean communication failure with remote control

Rheem Power Vent 2 water heater is flashing 4 times and there is no hot water. Model # 41VRP50NT What can I do to fix this? Do I need to call a plumber?


The flashing light is a trouble sequence light. Find your manual to see what 4 flashes means. It's usually attached to the side of the water heater tank. Try a quick fix by unplugging the power vent and see what happens.
