Safety first: Unplug the cooker before removing the control panel.

Surface cleaning: Wipe the control panel with a slightly damp cloth; avoid excessive liquid.
Inspect overlay: Look for cracks or lifting edges where moisture could enter. If present, the keypad may need replacement.
Check ribbon cable: Open the control housing and ensure the keypad ribbon cable is fully seated.
Replace keypad: If certain buttons remain unresponsive, install a new Binatone membrane keypad/touch panel.

Buttons are hard to press or do not register unless pressed very firmly.
