Laars Boiler Error E01: Ignition Failure
When your Laars boiler shows error E01, the control board is communicating that the boiler did not detect flame during ignition sequence. This diagnostic code helps our technicians identify the problem quickly and accurately. CANRO Heating & Cooling brings years of experience with Laars equipment and their proprietary error code system to every service call.
