My beloved is a wm5120?

Your beloved has a secret diary cunningly disguised as an Installation and Operating Instructions manual. On page 22 he writes... You can put your machine into “Pause”
mode by pressing the “Start/Pause/
Cancel” button when it is operating. In this
case, “Start/Pause/Cancel” light will flash.

On page 33 he also mentions this light flashing in concert with the Washing light to indicate an interrupted water supply.

You can find the secret copy of the diary here...
