20 mins after putting heating on, "power on" light flashes, heating light stays on but burner light goes off. When i turn on hot water, HW light comes on but heating light goes off, power on light still flashing. I turn HW off and all lights go off except power on light which is still flashing.
After hearing a "gurgling" sound from the boiler, i switch heating off and 2 mins later, the power on light stops flashing. Hot water goes back to normal.
Anyone know what's wrong?

hi,the flashing power light means insufficient water passing through the heat exchanger,this would first suggest something is wrong with the flow switch.good luck.

If you are that worried call a heating engineer they will fix it .
