My name is ***** ***** I look forward to helping you!

I am a factory trained and certified repair and installation technician for Rinnai, Takaghi, Noritz, Bosch, and Navien. Judging by your error code I'm guessing its either a Rinnai, Takaghi, Or Noritz. Can you give me a model number please?

Customer: replied 3 months ago.
it is a rheem ecosense.
Expert:  WCohn replied 3 months ago.

Excellent Rheem actually on makes tank style water heaters. They buy Takghi's and rebrand them.

Expert:  WCohn replied 3 months ago.

Error code 11 is no ignition. Is this a brand new install? Never has worked?

model number is *****
Expert:  WCohn replied 3 months ago.

Gas valve I assume is on? Have you purged the gas line?

Customer: replied 3 months ago.
for a little while, how long should i purge it.
Expert:  WCohn replied 3 months ago.

You should purge it as close the the water heater as possible and until you smell the gas. Is it a natural gas unit?

Customer: replied 3 months ago.
it is, and i could smell the gas.
Expert:  WCohn replied 3 months ago.

Can you hear the clicking of the gas solenoid valves? You should hear it after the fan comes on. Also can you hear the ignitor sparking?

Customer: replied 3 months ago.
i can.
Expert:  WCohn replied 3 months ago.

Does this model have a sight window for viewing the flame?

Customer: replied 3 months ago.
no
Expert:  WCohn replied 3 months ago.

Did you ever turn the gas off at the meter?

Expert:  WCohn replied 3 months ago.

If so make sure its on. Turning it on too quickly can cause it to lock up. If that happens turn it back off bleed the line then slowly turn it back on.

Expert:  WCohn replied 3 months ago.

Are you still needing help? Or did one of my suggestions fix it?

Customer: replied 3 months ago.
no, i tried it and still the same thing, i hear the clicking and it sounds like a fan starts and then the code starts beeping.
Expert:  WCohn replied 3 months ago.

Can you prove the outlet it is plugged into is properly grounded?
