Not likely,at least not from the rainstorm,

Are you getting a code on your circuit board(blinking light)

Do the popular thing and clean the flame sensor. Everybody's doing it these days, it's trendy but fashionable.

WE have pictures.

It flashes 3 times meaning pressure switch stuck open I changed switch and still had the same problem

Clean sensor?

You mentioned water... if the condensate trap is clogged, a flooded secondary heat exchanger could result in problems keeping the pressure switch engaged.

Admit it. You get a nickel for every time you post that pic don't you? :p

Sure but it is a dime
