Aqua-Hot WPX-274-313 Ignition Electrode for Webasto DBW 2010 Diesel Burner

The Aqua-Hot WPX-274-313 Ignition Electrode is an OEM-spec replacement ignition electrode designed for the Webasto DBW 2010 diesel burner used in Aqua-Hot and Hydro-Hot RV hydronic heating systems. Operating on a 12V DC electrical system, this electrode delivers the high-voltage spark required to reliably ignite the fuel-air mixture inside the burner head, maintaining efficient combustion and consistent heating performance.

Worn or degraded ignition electrodes are a common cause of burner misfires, hard starts, and reduced heating output. Replacing this component at the first sign of ignition trouble — or as part of routine annual maintenance — helps prevent unexpected heating failures during cold-weather camping.

Key Features:

• Direct OEM replacement ignition electrode for the Webasto DBW 2010 diesel burner
• Compatible with Aqua-Hot and Hydro-Hot RV hydronic heating systems
• 12V DC operation
• Delivers reliable high-voltage spark for consistent fuel-air ignition
• Prevents misfires, ignition failure, and reduced heating performance caused by worn electrodes
• It is strongly recommended to replace both electrodes as a matched pair for even ignition and consistent combustion
• Listed as OEM part WPX-274-313 in Aqua-Hot parts manuals for multiple system models including AHE-600-D03, AHE-675-D03, HHE-200-09E, and HHE-500-09M
