Miele keeps (or used to keep) spare parts for 20 years, and until the debacle with our second Miele washing machine (in 43 years, the first one lasted for 26 years, doing the laundry for a family with 6 kids), we’ve been very happy with the performance, reliability and longevity of Miele machines and the quality of the Miele service. This time too, their telephone operator was courteous and sounded efficient and knowledgeable. The repairman on the other hand was a complete let-down. But he was alone, and I guess he didn’t come prepared to take the machine back to the workshop. That being said, they lost a customer because the service was lousy when it mattered, and they didn’t have a suitable machine for our purposes.The biggest hassle is that whenever I search for parts I see them on sale from UK and Germany but none in US. So other than sourcing used parts, there is no option here like you have in Europe.
Only a year ago I replaced our Siemens dishwasher (a real POS) with a Miele, which has superior washing performance and, I hope, none of the problems you experienced.
