The cleaning method, moisture and any removed knobs are relevant. Several changed controls may share that event without proving that they all need replacement.
What the observation means
A knob refitted in the wrong position can misrepresent the function beneath it. Liquid applied directly to the panel can create another concern. Do not continue testing until the selected positions are clear and the appliance is safe.
A useful next step
Retain the product and work details, including whether parts were removed. Seek advice if controls stick, select unexpectedly or no longer indicate Off reliably. Do not spray lubricant behind the knobs or use heat to dry the panel.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
