oh no, its always something isnt it!!
I know the feeling though, yesterday I went to get the washing from the tumble dryer - its in like a conservatory type thing and everywhere was covered in condensation, despite the hose being hung out the window!! Then looked at the washing machine which had a load on and water was pouring out of the drawer!!
Thankfully after looking at both of them closely it was something really simple (a sock in the filter of the washing machine and the hose not in the right position on tumble dryer) but we thought for a while we'd need to repair/reaplce them - the tumble dryer is inly 3 months old as well
Fingers crossed the things you replace will last another 7 years xx
