I’ve recently have had to deal with cold showers due to my rinnai acting up all weird out of nowhere, last year I faced something similar but was able to fox it myself, but I’ve had no luck recently with this new issue; I’ve paid all my utilities, but it seems this issue may be related to the fans. Usually when I run water I can hear the fans start to run but after about 15 seconds it stops and gives me the error code, I was wondering if there was any easy fix I’ve been neglecting to try since turning the water off and on hasn’t helped. I know that the obvious solution is to call someone to repair it but I really just want to figure out if theres a way to fix this without having to cough up any cash for potential part replacements. Ive attached images below that may help, but let me know if I need to show more images. (In the worst case it cant be fixed manually please let me know any good repair services.)
