T-K3-OS with no error code or blinking light

[Cold Showers]

Hey Terry, first time posting but have used this for some excellent information in past. Thanks.
I have a T-K3-OS that has run fine for about 10 years, now I get nothing from it. Cold water only. It will not ignite at all and the power is good, gas is good and no blinking lights for any error code. Reading on the subject I think it a mis- communication between the T-K3-OS and the temperature remote controller. Tried the reset and even cleaned the igniters. Any help would be greatly appreciated. Thanks again for all the great post prior.

Lots of times no error codes mean flow switch

Its not recognizing your using water, either that or you didnt pay the gas bill

Thanks, the gas has been paid as all other gas appliances are working fine, I will check the flow. I have cleaned the filter that had very very little buildup on it.

Still,

Flow switch has a working impeller and power thru motherboard is at 110v. Unit is 11 years old and never had issues. Might be time for another.
