i would report that to the company you booked the holliday house from Luke!
when i whent on holiday to the west of wales (i am from the south of wales)
we had an indesit in the cottage wich was essentialy the same model of indesit we had when the old hoover softwave bit the dust excep our old indesit had the old style indesit drum not a whirlpool type drum, anyway it had a mouldy seal from the cottage owner being bitchy and saying you cant use powde (we had tablets so we stuck them in the drum)
at the end of our holiday i sayd to the owner "leave the door on the washer open to let it breath, its smelly and is mouldy!"
