What Hob Glass Cracked means on your Asko range (asko hob glass cracked)
This is a safety symptom, not a code — a cracked glass-ceramic surface on an Asko cooker is not something the control electronics report, and it is not something to work around. Once the surface is compromised, spills can reach live electrical components underneath, and continued heating can widen the crack suddenly. This is a stop-use situation on any cooker, imported or otherwise, until the panel is replaced.

Symptoms
To be sure your Asko range has this problem and not a close relative, line up what you are seeing against the signs below. On the range these can show up singly or several together, easing in over time or arriving suddenly after an outage, a spill, or a service visit.
- A visible crack, chip, or star fracture is present anywhere on the cooktop glass
- The crack may lengthen or spread after further heating cycles
- Liquid seeping into a crack can cause crackling, sparking, or unusual smells
- A section of the glass may feel loose or slightly raised near the damage
Common causes
There is rarely a single obvious cause on an Asko range, so the possibilities below are sorted from probable to unlikely. Testing them in that order tells you whether your range needs a simple adjustment or a repair with genuine OEM or trusted-supplier parts.
- Impact damage — a dropped pan, utensil, or heavy object struck the glass
- Thermal shock — cold liquid or cookware hit an already-hot zone and the sudden temperature change cracked the glass
- Pre-existing stress fracture — a small chip from years ago has finally propagated into a full crack under normal heat cycling
Troubleshooting steps you can try
Go through the steps on your Asko range from top to bottom before booking a repair, since the early ones cover the common causes. The moment mains voltage, gas, a hot cavity, water, or a sealed component enters the picture on the range, hand the job to a qualified technician.
- Stop using every zone on the cooktop immediately, not just the cracked area.
- Switch off power to the cooker at the breaker if the crack is significant or spreading.
- Do not clean the cooktop with liquid cleaner until the crack is assessed, since liquid can enter the crack.
- Keep the area clear of pans and heavy objects until the glass is replaced.
Parts a technician may replace
A technician diagnosing your Asko range may inspect, test, or replace the glass-ceramic cooktop panel, heating coils beneath the glass, and seal and frame trim, depending on which one has actually failed. Reading the range’s model, serial, and Art. No. before ordering avoids replacing more of the range than the problem requires, and keeps the fitted part an exact match.
When to call a technician
A cracked hob glass always needs an experienced technician to replace the full glass-ceramic panel on the Asko cooker; there is no safe partial repair.
