CORONA 　FH－A4612GY 　E0エラー　部屋が臭くなる

CORONA FH-A4612GY E0 Error - Room Stinks November 12, 2025 The E0 error caused the room to smell (probably incomplete combustion). At first, there was no spark sound from the spark plug. I thought it was a problem with the igniter. Maybe I just didn't hear it, since my hearing for high-frequency sounds has been getting worse recently. I thought it might be the igniter, but I'm still an amateur. Is the real cause dirty spark plugs or combustion tubes? I originally thought I should replace the spark plugs and combustion tubes (the mesh-like parts), but I'll wait and see if the same problem occurs again.
