How to fix no spark on my AEG HGX6400SM Hob?
- BBrent GreeneAug 5, 2025
If there's no spark when activating the spark generator on your AEG Hob, there might be a few reasons. First, check if the hob is correctly connected to the electrical supply. Also, verify that the fuse hasn't blown; if it repeatedly blows, contact a qualified electrician. Ensure the burner cap and crown are placed correctly. After lighting the flame, keep the knob pushed for equal or less than 10 seconds, so that the thermocouple is heated up sufficiently. Finally, make sure that the injector is not blocked and the burner crown is clean.
