What to do if the Heylo K 220 burner starts up, but indicates interference, and the red signal lamp lights up?

If the Heylo Heater burner starts but shows interference with the red lamp lit, the issue could stem from several causes: * The oil tank may be empty, in which case you should refill it. * The oil pipe might not be connected, or the main tap could be closed; inspect the pipeline and main tap. * A dirty oil filter can cause this issue, so clean the nozzle filter, pump filter, and pre-filter. If needed, change the nozzle. * The oil suctioning pipe may not be sealed properly, causing the pump to suck in air. Ensure the oil suctioning pipe is sealed and that the oil in the reverse flow pipe is free of bubbles. * Lastly, the oil pump might not be producing enough pressure. In this case, set the pressure correctly.
