Miele: 3717 Fix ((full))

Fault Code 3.7.17 (.200) on Miele appliances indicates a connection failure with the Miele app, which is typically resolved by checking WiFi signal strength, ensuring router ports 80, 443, 53, and 5353 are open, and disabling network restrictions or ad blockers. For persistent issues, switching from custom DNS to the ISP default or performing a hard power cycle of the unit is recommended. For comprehensive troubleshooting steps, visit the Miele support page

  1. Search for a "Miele S5 Replacement Hose" on Amazon or eBay.
  2. Look for third-party manufacturers (Videotec or WOWParts). They cost $35–$50.
  3. Installation: The new hose will have a 6-pin connector. Plug it into the canister. Screw the threaded collar tight.
  4. Turn the vacuum on. If the code is gone, you are done.
