Dometic water heater soot, delayed ignition, or lazy flame
Use this when Dometic maintenance guidance points to soot, delayed ignition, ignition outside the combustion area, or a flame appearance change.
Owner-safe checklist
- Turn the water heater off.
- Keep the exterior vent area clear from normal safe access.
- Do not clean or adjust combustion parts as an owner troubleshooting step.
- Call a qualified RV appliance technician before operating again.
