2years ago, we got rid of our Ariston washer drier, coz the main bearings had gone - Ariston probably havent sold to the UK market for about 10 years.
I changed the main bearings on a previous Hotpoint washer, and managed to keep it going for about 16 years, but I've decided it is no longer worth the hassle.
We probably used the drier 2-3 times. I used the same sheets and quilt cover for 2 years, managing to wash and dry them withing 12 hours, about every 10 days!
By keeping an eye on the weather forcast, and having an old (1989) boiler with an airing cupboard and a big enough landing for airers,, we manage to keep washing turnover under control, with no need for a drier.
I'm probably not helping, but , in my life, I'd probably not buy another washer-drier, coz I can cope without (and, yes - it's maily me who does laundry,as well as cooking, washing up, ironing, driving, earning,etc.)
