The answer up front
This code says the keypad and its wiring sent the control something it cannot interpret as a keypress. The machine is not unsafe, but a keypad that reads a press nobody made is a reason not to leave it running unattended. Steam from the cooktop drawn behind the console is both the commonest cause and the cheapest to rule out, so it goes first.

|---|---|
| E03 | The Keypad (User Interface) reported a problem to the control board. There may be a problem with the Keypad (User Interface) or the associated wiring. |
The observable side of this fault
- The console responds differently when the appliance is hot — Heat expands everything behind the panel, and a marginal contact behaves differently at temperature.
- The problem started after the front was cleaned — That timing is the diagnosis: liquid at the bezel edge is the usual route in.
- NEAR MISS - the display is blank and no key responds — That is a supply or board fault, not a keypad fault, and it is a different page.
The ranked causes behind this reading
- Moisture or cleaner behind the panel membrane — Ranked first because it is the cause that cures itself: liquid bridging two traces reads as a held key, and a day of drying with the power off removes it.
- The ribbon connector between the panel and the board — Second: a ribbon that has crept out of its socket with heat produces exactly this, and it is a reseat rather than a part.
The order to work through it
- Work out which keys respond and which do not — A pattern tells a technician whether the panel or the board is answering.
- Check nothing is resting against the console — Free, faster than any other check on the page, and it is sometimes the whole fault.
What an owner can safely do
- Wipe the panel with a barely damp cloth, never a spray — Spray finds the gap at the bezel and puts the fault straight back.
Tools: soft clothAbout 5 min
- Clear everything off and away from the console face — A tea towel over a console is a held key as far as the control is concerned.
About 5 min
- STOP HERE if the console has to come off — The ribbon and the board behind it are service work, and the panel is easy to crease beyond repair.
Where the risk actually is
Safety
Power off at the breaker or at the plug before any panel is removed - a capacitor can hold a charge after the power is off. The owner-side checks on this page need no panel removed at all. If you get as far as wanting a meter on something, that is the point to call rather than the point to improvise.
When to call a technician
Where an owner stops: call when the panel still misreads after it has dried, or when keys have gone dead permanently: a membrane and a ribbon are both service parts and the panel comes off to reach them. And where nobody should wait at all: call at once if the machine starts a cycle nobody selected. A control acting on presses that were never made should not be left connected.

Which model lines this reading applies to
The reading on this page applies to the model lines that use this console layout. Two things are deliberately absent: anything that varies by model line, such as part numbers and wiring detail, and anything the manufacturer publishes only to technicians. Where a page exists for your specific family or model, that page takes precedence over this one, and the index linked below points to it.
