Hi all, I've read a copious amount of threads about the E05 error however thought to ask one last time before spending the $300 for the control board. I get the SFS light and the "push ON" reading just stays at 80 then comes the E05. This is after the heater ignites and seems to run just fine - warm water flowing from return line, heat from the Stack flue etc.
I've replaced Thermistor (was broken - didn't throw error funnily enough) and Thermal regulator (tested after purchase before installation) and ignitor (broke this one when trying to clean it lol).
I have also broken open the entire unit, cleaned the cone (inside and out) that is inside the "heater tube", dismantled and lubed the fan assembly. The heater coils appear to be fine, no erosion around the copper on the manifold, I did not run water through each one however there was no visible "clogging" and no indication of any leaks, the basin was dry (a little rust which I vacuumed out).
I've checked continuity on the white wires that run to the SFS and have replaced the SFS (which still reads 3.6-4.0 MOhms).
I did clear some loose plastic (haven't identified where it might have been from) out of the bypass valve which appeared to be in great shape otherwise.
Are there any steps / ideas I have not listed that might be causing the 80 SFS temp reading and the eventual E05 or am I just looking at a control board?
thanks,
Rob
