# Bosch induction cooktop not recognizing the pan

### The fastest diagnosis is the code

If there is a code about supply voltage, stop — that one is about the building rather than the cooktop, and no part inside the appliance will improve it. Everything else on this page starts with the pan.

### The cookware is part of the appliance

An induction zone works by inducing a current in the base of the pan, and the pan has to be able to carry one. Aluminum, copper and plenty of stainless steel cannot. A fridge magnet on the base of the pan is the entire test: firm grip means it will work, weak or none means it will not, and no repair changes that.

### One zone or all of them

Take a pan you know works and try every zone. If one zone alone refuses it, that zone’s coil or module is the question. If every zone refuses every pan, and there is a voltage code on the display, the answer is upstream of the cooktop entirely.

The pan is not ferrous

Induction works by inducing current in the base. Aluminum, copper and most stainless steel without a magnetic layer simply do not respond. A fridge magnet on the base settles it in a second.

The base is too small or warped

A pan smaller than the zone's minimum, or one that has bowed and only touches at the rim, will not be detected reliably.

The pan is off-center

Or straddling two zones on a flexible cooking area. Both produce intermittent detection that looks like a problem with the cooktop.

Supply voltage out of range

Has its own published code. It is a building or utility question, and it is worth reading before booking anything.

The coil or its module

When one zone never detects anything while the others are fine. That is a real failure and the expensive half of this appliance.

Put a magnet on the base of the pan

If it does not stick firmly, the pan will not work and the cooktop is fine. This is the whole answer surprisingly often.

Try the same pan on every zone

Works everywhere except one zone: that zone. Fails everywhere: the pan.

Center the pan

And check the base sits flat — put it on a counter and press each edge. A rocking pan is a bowed pan.

Photograph any code

Particularly the voltage one, which changes who you should be calling.

Sometimes it is the pan

What it usually means

Beeps and switches off after a few seconds

Works with one pan, not another

A pan symbol on the display
