Miele is alright until it goes wrong then it becomes very expensive. We have a 5 year old combi oven / microwave / grill that is very temperamental and when the service guy came out his diagnostics showed nothing wrong. Problem persisted so called them back and they wanted another call out fee despite him not fixing it in the first place.
A rubber seal for the door – a very simple seal at that – £30 + Vat.
Had a miele conduction hob go wrong too within 5 years. The neff we replaced it with seems much better.
Washing machine and tumble dryer – always buy cheap (Beko) and if it breaks out of warranty then replace rather than fix unless it’s just a seal or pipe.
