Fault-finding an electrode boiler can be a bit technical, but here are some general steps to guide you:

  1. Check the Power Supply: Ensure the boiler is receiving power. Look for tripped circuit
    breakers or blown fuses.
  2. Inspect the Electrodes: Clean them carefully and check for any visible damage. If they’re worn out, they may need replacement.
  3. Inspect the Control Panel: Faulty wiring or a malfunctioning control panel can cause issues. Look for loose connections or signs of damage.
  4. Inspect contactor(s): Inspect contactors and replace if worn.
  5. Examine the Water Supply: Electrode boilers rely on water conductivity. Ensure the water supply is adequate and the conductivity is within the required range.
  6. Faulty pump tripping circuit breaker: check that the pump combined circuit breaker/overload protection has not tripped. Reset after ascertaining the reason for tripping.
  7. Faulty pump: check that the pump is operating properly. If water supply cannot be sustained when the boiler is up to pressure, a worn impellor is probable. Inspect and replace if necessary.
  8. Test the Safety Features: Ensure that safety features like pressure relief valves and
    temperature sensors are functioning properly.
  9. Consult the Manual: Your boiler’s manual may have specific troubleshooting steps for your model.

If you’re unsure or the problem persists, it’s best to contact a qualified technician to avoid potential hazards.
