Troubleshooting Tips:

Do not perform any of these steps as a homeowner if it requires going inside the boiler!

  1. Check Power Supply: Ensure that the main power switch for your boiler is turned on and that the circuit breaker supplying power to the boiler is not tripped.
  2. Inspect Electrical Connections: Examine the electrical connections between the boiler and the power supply to ensure they are secure and undamaged.
  3. Reset Circuit Breaker: If the circuit breaker has tripped, reset it by flipping it to the “Off” position and then back to the “On” position.
  4. Test Power Outlet: Plug another electrical device into the same power outlet to verify if it’s functioning properly. If not, the issue may lie with the power supply itself.
  5. Call Your Electricity Provider: If you suspect a power outage or disruption in your area, contact your electricity provider to inquire about any ongoing maintenance or faults.
