Unlike a clogged hose or a full bag, the 3717 error is electronic. Miele vacuums use a two-wire communication system (often a proprietary Miele bus system) to send signals from the handle (where you press the "+" and "-" buttons) down the hose, through the telescopic tube, and into the main circuit board inside the canister.
The Breakdown:
In human terms: The brain of the vacuum (the circuit board) cannot hear the fingers pushing the buttons on the wand. Because the vacuum is safety-driven, it shuts down the motor to prevent runaway suction or electrical issues.
