First day off in two weeks. I slept in to 5:30am, get up find note from wife, no hot water, oh boy time for fun. Luckily master bath has it's own WH. Hot shower then figure out why main WH isn't running. I watch some YouTube videos, seems easy to replace the thermocouple. I get the burner assembly out, doesn't look simple. Find the manual, it says replace the whole pilot assembly which is $77 for the part not 10 bucks for a hardware store thermocouple. It is a State Select High Efficiency WH. Damn. Can't get one on Saturday but can order it. Somewhere on the internet it says to blow out the pilot tube, I apply compressed air, some crud comes out, I can't get the pilot to light even allowing time for gas to come through. Go to order part, all ready to put in info and CC, figure I will try one more time. Blow more air then verify it is coming out pilot end. Reassemble WH 2nd time then allow two minutes to bleed air out, click click click, pilot lights, hold button for one minute, turn knob and WOOSH main burner comes on and stays on. It finally cycled off, look in the stupid little window and there is a good looking pilot flame in there. Run the hot water for a while and WOOSH main burner comes on again which is a big relief.
