Here's the [document|27516|tech sheet] for the washer that may help.
On p.2 at the bottom of the page (in the middle next to the French language side of the page) it describes how to check the keypad operation. In the ''Keyswitch resistance check table'' it shows the connection test points for the Start/Resume button i.e. P1-12 to P1-4. Note that there is a diode between the test points for each key function.

I've never opened a this particular type of keypad assembly but if they're like laptop keyboards then you may have to tread warily if it tests open circuit with the switch operated and you decide to open it up to check the switch (or the diode or the switch connection to the pcb) as you can create more problems than what you originally had. At least if the switch tests OK from the connector cable you know it's not the switch, the diode or the board.

Hopefully this is of some help.
