Look along the top edge of the door on an SHP53TL5UC and you find its controls, which is the first clue to its age. This is an early pocket-handle Bosch. Its stainless tub is 23 3/4 inches deep, it takes 15 place settings, the upper basket is RackMatic, and drying is by condensation.
A control strip on the door edge is exposed to whatever drips down while the door is open, and on this generation it was sealed less thoroughly than on current models. A spill from years ago can surface much later as a panel that behaves strangely.
When an owner reports that the keypad has a mind of its own, we start by asking whether liquid ever reached the top of the door. The rubber along that edge also hardens with age, and it can let steam creep into the panel.
That is not a fire concern in itself, but it means the machine could fill and run with nobody watching. Switch it off at the breaker and close the water valve until it has been repaired.
Sometimes, if the corrosion is caught early. Once the conductive tracks on the membrane have eaten through, only a new panel will give dependable results.
We would not, if the keys are acting up. Unplanned starts and stops can leave water in the tub or a cycle half finished, so leave it off until we check.
