Code Fd

[Gwagner961]

I get a Fd code on my Girard Endless hot water heater in my camper. I know what it is but but how do I clear it.

Does this video hold the key?

Thanks for the reply but my unit does not look like yours and I do not see a reset button. I do have a removable panel that does give me access to the mother board. Did not see reset button there either.

I used to have a Girard; but now have a Truma system. All IU can do is try to find you the right link to something useful...
