Bertazzoni Rangetops SPARK-CONT Error: Continuous ignition clicking
What Does SPARK-CONT Mean? SPARK-CONT describes continuous ignition sparking on a Bertazzoni gas rangetop — the rapid clicking that should stop the moment a burner lights or a knob is returned to the off position instead keeps going. On the brass star-burner rangetops in the Professional, Master, and Heritage series, this is almost always caused […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. Continuous sparking near an active gas flame is a minor ignition hazard and the persistent electrical arc can damage the electrode tip over time. Allow the rangetop to dry fully; if clicking continues after drying, arrange service before further use.
Can I reset the code?
No. There is no electronic reset — continuous clicking is a mechanical or moisture condition. It resolves when the moisture evaporates or the micro-switch is replaced.
When to stop immediately?
Stop if you notice: Clicking persists for more than 30 minutes after the rangetop surface has been dried, Smell of gas near the rangetop while continuous clicking is occurring.
Symptoms You May Notice
Rapid clicking continues from burners even with all knobs off
The characteristic rapid clicking of the electronic ignition persists across one or all burners after the cooking session ends and knobs are returned to the off position, indicating the ignition circuit is not releasing.
Clicking and sparking continue after the flame is established
After a burner ignites and the knob is released from the ignition detent, sparking does not stop — the electrode continues to fire with the burner already alight, posing a minor ignition risk on the active flame.
All burners click simultaneously when only one is in use
Because the ignition module is shared across all burners, a stuck micro-switch for one burner can trigger continuous sparking at every electrode simultaneously.
Possible Causes
Moisture bridging the ignition switch contacts
Water from a boil-over or surface cleaning has entered the ignition switch cavity beneath one of the knobs, creating a conductive path that mimics a pressed knob and keeps the ignition circuit active.
DIY PossibleIgnition micro-switch stuck or corroded in closed position
The micro-switch inside the burner knob shaft has become mechanically stuck in the depressed (spark) position due to corrosion or physical damage, continuously signalling the ignition module to fire.
Requires ProfessionalSafe Checks You Can Do
-
1
Dry the rangetop surface and around the knobs
If the clicking started after a boil-over or surface cleaning, turn all burners off and allow the rangetop to air-dry completely. Remove the burner caps and grates and wipe beneath them with a dry cloth, paying attention to the area around each knob shaft.
Directing a hair dryer on the low-heat setting around the knob bases for 2–3 minutes can accelerate drying when moisture is the suspected cause.
-
2
Test each burner knob individually
Once the surface is dry, press and release each knob individually to identify which one triggers the continuous clicking. The faulty knob will produce clicking that does not stop when released, isolating the stuck micro-switch location for the service technician.
Do not attempt to disassemble the knob shaft or ignition switch yourself — these are internally mounted and require rangetop panel removal.
When to Call a Professional
Contact a qualified technician if:
- Continuous clicking does not stop after a full dry-out of the rangetop surface
- One knob can be identified as the source and clicking stops only when that knob is pulled off
- Electrode tip is visibly cracked or worn from sustained arcing
