# Asko cooktop glass replacement

### Not cosmetic, and the availability question comes first

A crack breaks the seal between the cooking surface and the electronics beneath it, so spills and steam travel down onto the coils and the board. The failure that follows is electrical and it does not announce itself first, which is why the advice is to stop using the hob and open the circuit rather than the control panel. Two things are established before a figure is quoted: what has already got through, which decides whether this is a glass job or a glass and electronics job, and whether the panel for that exact model can still be sourced.

What this involves

Stop using it and isolate at the breaker — this is not cosmetic

Availability checked before a figure is quoted, not after it is accepted

What the crack has already let through decides whether glass alone is enough

Isolate and assess the ingress

Power off at the breaker, then the underside inspected for what has reached the coils and the board. That finding decides whether this is a glass job at all.

Confirm the part exists before pricing

The glass sourced against the exact model, with its lead time, and the answer given before anything is committed.

Fit, seal and test every zone

Sealed to the stone properly and all zones run, because a hob assembled around a new top still has to be proved as a whole.

### It is only a hairline crack.

It works today. The mechanism is what passes through it over the following weeks — a boil-over, a wiped surface, steam — and the electronics beneath are not sealed against any of it.

### How did it crack? Nothing was dropped.

Often nothing was. Thermal shock does it: a cold wet cloth on a hot zone, a pan boiled dry and then moved. Occasionally it is the installation, where a top was clamped into stone with no room to expand — and that is worth correcting, or the new one goes the same way.
