so January 2017 the expansion tank had to be replaced... then last winter, a year to the day on
January 19th the boiler went out again. I called the landlord who was like "just hit the restart button" which I did and it restarted. To his credit, the landlord sent out a service guy anyway who changed the oil filter and cleaned the injector nozzle and said "it was dirty. that was certainly your problem" A few weeks later though it wouldn't start again, I hit reset and it worked. Then was fine all spring and summer (our hot water worked all summer so it had not problem kicking on a few times a day).
This fall, I turned the heat on for the house and the boiler kicked on but after a couple weeks it shut off. I hit restart. Then a couple more weeks. Then we were gone for 5 days at Christmas and came home to a freezing house. I hit restart. Then it was only a week and I had to do it again. And then a few days later so I texted the landlord last Friday. He said he'd call the service company, which he did on Monday. They didn't get back to him until Thursday and said they'd come out this morning (Friday, at 9:30) which is in 2 hours. Meanwhile, I've had to hit restart once a day all week. I did it last night, then again at 6 this morning. Then it went out after one cycle and restart doesn't work any more. Perfect timing.
So as of right now, we have no heat at its 20F out (with a 7-degree windchill)! Luckily the service guy will be here in 2 hours. I sure hope it just needs another quick cleaning and he can get it fired back up. But I'm a little nervous its a bigger problem since last years cleaning didn't really solve the problem, at least not long term.
