Ensure the shipping struts are removed from the washer.

Ensure that the shipping struts are NOT removed until the machine is in your laundry room. Sometimes installers will remove them on the truck, and this is not a good practice. There are lots of bumps between the truck and your laundry room. Keep the struts in place until you are as close to the final location as possible.

Make sure that the machines are properly leveled. Ensure you see the installers use a bubble level and verify for yourself that the units are perfectly leveled before the installers leave. Miele says you should run a sanitary cycle before first use. Start that cycle before the installers leave to confirm the cycle is working. Install the units downstairs.

I hope you are using Miele authorized installers. If you are in the US, that will get you a 2nd year added to your warranty. If you bought any extended warranties, make sure it's a Miele extended warranty and not some third party excuse for a warranty.

Thanks to both for your tips. Sshrivastava, your specific points were very helpful, and yes, I had Miele authorized installers. Now I will hope for problem-free operation of both appliances.
