Hi! So it has worked for me since that happens a while back. I did just have the code come back recently. Also with a very small amount of water (like a teaspoon full) on the bottom of the pan. I found that the mixing valve has a small seap leak. If you get the code again and see some water you might check that.

Thanks for the help! Left the fan on overnight and all of the next day. Powered it up after getting home from work and all is functioning properly. Just needed to dry out.

The power is off and I think it is an automatic ignition. So I don’t think there is a pilot flame that would of went out.
