rinnai ru98 not always working
we built a house last year and installed a ru98 rinnai water heater. It worked great for about 8 months and in the last 4 months or so it doesn't start up sometimes. I would just wait 30 seconds then try the hot water again and it would work. It has got progressively worse until last night it wouldn't start at all. i had to reset the hot water heater ( un plug ) 5 times before it worked. it was flashing a code 11 so no flame present. i double checked the tank and lots of propane. what else can i look at ? sensors need cleaning or anything i can look at? we are on well water but have a filter system. please point me in the right direction. I am mechanically knowledgeable, just need help starting the trouble shooting. the nearest rinnai service is about 300km away. there is no point hiring the local plumber because i am better then he is.
