Oil fired hot water heater troubleshooting. To check for presence of water in the tank apply some water sensitive paste onto a long stick. We let it run until it stopped on its own after several minutes. And oil burner noise smoke odors. If it indicates water you ll have to drain the tank and inspect it for cracks.

This will be the box shaped object that produces the spark on the electrode.

If there is electricity reaching the system it will attempt to restart. Close the cold water valve this valve lets water enter the heater tank open a hot water faucet located nearby this relieves the water pressure in the tank remove the sacrificial anode.

The boiler s automatic filling system controlled by the pressure reducing valve should maintain the proper water level at 12 to 15 psi of pressure. If you ve checked all of those causes and found nothing wrong you might try to reset the entire heating system. Install a new sacrificial anode. Arrange to repair all cracks.

If electrical switches oil tank level and thermostat have been checked and the furnace will still not operate the reset switch on the oil burner is the final troubleshooting task before calling.
