I realise this is a bit how long is a piece of string but...
How long would you expect a decent brand washing machine to last and what's your average no. of loads per week?
We think ours is 14 years old (DH bought it before he met me) and is Miele so came with 10 year guarantee, so clearly meant to last a while. It now does 5 or 6 loads a week since having DD (18mo) but before her 3 a week and when it was just DH 2 a week (first four years of its life).
It seems to be leaking from the door so investigating what to do- the seal looks fine. I think it's had much less use than the average washing machine so could be expected to last longer.
