slimline dishwasher plse (Yattendon RG18)

Mine has stopped working, the on off button isnt working or lighting up, probably an easy fix but I'm stuck for now and severely debilitated so am dependent on my dishwasher, has anyone got one at all, only a slimline will fit, and the know how to plumb it in? I'm guessing disconnecting mine will show how that is done!
