Zanussi ZWD12270W – no power

Hi there.
I’m hoping someone on here can help me ?
We’ve got a washer dryer that’s 18months old & been used 2/3 times a week.
The other week it packed up – there’s no lights/clock or anything at all
There’s 240v down to the back of the rotary programme selector switch & the contacts inside the switch are clean & contatcing ok.
Where do I check next or is there somethinng that’s a “known issue” with these.
Zanussi have been very unhelpful – Suggesting that we pay for their engineer to come out ( they won’t give me a price ) & if he deems it to be beyond repair they’ll contribute towards a new machine !!!

I think a £400+ machine should last a bit longer than this.
To tide us over we’ve pinched our old Zanussi 10+ years old back off my mother who we gave it to on geting the new one & it’s still going strong.
