6.2 TROUBLESHOOTING OIL BOILER
Problem Cause Remedy
13. Water pump runs
intermittently
1. Scale on probes. Check probes, clean as required.
2. Bad pump contactor. Check to ensure the contactor is live. Check to ensure the
contactor coil is being pulled in. Replace as required.
3. Pump motor damaged. Check the pump circuit is live. If the circuit is live but the
pump is not running, replace the pump.
14. Boiler continues
after shut down
1. Oil valve defective Check the valve is opening and closing.
15. Oil fumes coming
out around the oil
pump housing
1. Bad draft condition Check the draft with a gauge, should read neutral. May
need to install a barometric damper.
2. Venting of room Ensure the boiler room doors are closed on shut down and
the recommended vents are clear.
16. 1. Pump does not shut off. Dirty probes, clean or replace as required.
2. Relay failed. Check relay is secure on its base, if so replace the relay.
3. Earth connection. Check for tightness and clean.
4. Vacuum created with the boiler
off.
As the boiler cools it pulls water from the system. To
prevent this, add an anti-vacuum valve on the steam
gauge assembly piping, this valve closes under pressure
and opens under vacuum.
