problem with oil burner riello

[robert-o1978]

Hello. I have a problem with the oil boiler. After the summer season, he doesn't want to work normally. It started with blasting electric fuses. After looking inside, I saw condensation. Then it stopped working with the lid closed at the front. When the lid was open it worked. And since yesterday, I don't want to work normally, even if the cover is removed. I am enclosing the video in the attachment. I am asking for advice because no plumber who was here knows what it could be. Thank you

You need to have a regular service on oil burner, I'd definitely recommend you book in a service ASAP.
You could try pulling out black wire with square rubber end and wipe the bulb on the end before re-inserting it ?
