Weil Mclain Ultra 105 - b25 code
I recently did a maintenance kit on my Ultra 105,
About a day or two later I started getting a b25 error message. It came and went, but every few days it showed up more frequently over the course of the last 2 weeks. Now I woke up this morning and the boiler wont stay on for more than a few minutes and is constantly showing the b25 code
I'm a newbie, so I don't know any technical terms or abbreviations
