I've had an intermittent fault with my Riello oil burner. When it turns off it won't restart. The cutout light comes on. When I press the restart it runs through the normal restart cycle but fails to relight.
The pump pressure is 8 bar and I've checked flow by bleeding it so no problem there. The solenoid is working. I've replaced the nozzle, the opto sensor, the solenoid valve and the control box, cleaned the pump filter and the line filter. All to no avail.
After it has cooled down it restarts OK but won't do it automatically. I can't think of anything else to try or test.
Has anyone any ideas?
