The bridge-zone feature on the ZEU365 links two adjacent elements into one larger cooking area for oversized cookware — when that link fails, the two elements typically still work independently, which is a useful diagnostic clue pointing to the bridge relay rather than either element itself.

A cracked or chipped ceramic-glass surface on a cooktop like this is a safety issue as much as a cosmetic one — a compromised surface can allow moisture into the electrical parts below, so we treat glass damage as a priority repair rather than something to schedule around.

Sugar boil-overs, dragged heavy cookware and the wrong pans are what most often harm an induction cooktop glass surface; here is how to avoid each.

The ZEU304 is a straightforward electric radiant cooktop — no induction electronics involved, so problems are usually isolated to a single zone’s heating element or its dedicated control circuit rather than the whole unit.
