Hotpoint dishwasher DF61?

I have a hotpoint aquarius df61 The dispenser lid is attached to the machine/dispenser with a spring...
However the spring is still attachedto the actual dispenser but is no longer connected to the lid.. the lid has come off .....
I saw the peg that attaches the lid to the spring and it seems worn out... what do I do... the spring is still in good shape
