What this code means, briefly
The short reading of E11 on a Bosch oven: the touch keys are not operating properly, which may be condensation on the keypad. The oven is only as usable as its panel; if keys will not respond, dry the panel and power-cycle before trying to cook on it. Most of what follows is diagnosis rather than repair, and the repair end of it is a technician job.

| E11 | The touch keys are not operating properly. This may be due to condensation on the keypad. |
What you actually observe
- Keys respond intermittently or not at all after cooking — Steam from the hob or the cavity reaches the panel, and the panel reads it as touch.
- Tones sound with nothing being touched — The panel is reacting to something on its surface rather than to a finger.
- NEAR MISS — the panel is dark and does nothing at all — That is a supply or a link fault rather than a surface one, and it is checked differently.
What triggers E11, most likely first
- Condensation on or behind the keypad — It goes first because the manufacturer names it: moisture is conductive, a touch panel reads conductive contact as a finger, and the fault clears as the panel dries.
- Liquid or a greasy film on the panel — A touch panel reads a conductive film as a finger, so a surface that merely looks smeared behaves as though it is being held.
- A failed interface board behind the panel — Last: the expensive candidate, and the only honest way to reach it is to have the surface clean, dry and unloaded first.
What to check first, second, third
- Clear everything off the panel and look for misting on the glass — Visible condensation is the answer, and it is free to confirm.
- Clear everything off the control surface — Not most things — everything, including a cloth draped over the edge.
- Dry the panel thoroughly and look along it in reflected light — A film shows up at an angle when it is invisible head-on.
- Body: Map which keys work before cleaning anything — a single dead key and a whole dead panel are different faults with different costs.
What an owner can safely do
- Clear and dry the panel, leave it off until the glass is clear, then power-cycle and retest — Ventilate the kitchen as well: steam from a hob below the panel keeps arriving while you work.
Tools: dry clothAbout 60 min
- Clean the surface properly and dry it fully — Mild detergent on the cloth rather than on the glass, then dry it completely before powering up.
Tools: cloth, mild detergentAbout 15 min
- Cut power at the breaker for a minute and restore it — A panel that has locked out needs the control to re-read a clean surface from cold.
About 5 min
- STOP HERE — the membrane and its connector are behind the glass — Getting behind a control panel means live terminals, so that is service work.
Safety first
Safety
Isolate the oven at its breaker before removing a panel and treat the terminals as live until you have. Let the cavity and the glass cool fully first. On a gas model, never switch anything on or off if you smell gas: leave and call the gas utility from outside.
When to call a technician
Call once the surface is clean, dry and clear, the appliance has had a full power cycle, and the panel still will not accept input.

Scope of this reading
What is written here is generalized to the Bosch oven line rather than to a single family. Deliberately absent: connector positions, wiring colours, part numbers and the service sequences for your particular build, all of which vary across the line and belong in the manual for your model. If a model-specific page for this code has been published it is linked from the index below, and that page outranks this one for your unit.
