Miele C1, C2, C3 and Guard canisters showing “Cable partly wound during a cleaning longer than 30 minutes” has a specific manufacturer-backed troubleshooting path. Match the exact light, sound or behaviour before cleaning, resetting or ordering anything. Confirm “Cable partly wound during a cleaning longer than 30 minutes” exactly, including the full number, colour, flash order, spoken phrase or screen text. If any element differs, use the guide for that other indication instead. Miele — Guard operating instructions documents this condition for Miele C1, C2, C3 and Guard canisters. It identifies the branch to test, but it does not by itself prove that a battery, motor, board, sensor, dock or replaceable part has failed. Switch off and unplug, let the cable cool if warm, then pull it fully out before any session expected to exceed 30 minutes. Miele warns that a partly wound cable can overheat; do not continue merely because the vacuum still runs. Switch the vacuum off and disconnect its charger or mains plug before removing an accessible tool, bin, filter or brush. Never open the motor body, charger or battery pack. Run only one normal start, charge or cleaning cycle after the documented check. If “Cable partly wound during a cleaning longer than 30 minutes” returns unchanged, record the code, model and serial number and contact authorised Miele support instead of repeating resets or guessing a part.

Next step
Repair, replace a part, or arrange a diagnosis?
Use the checks and stop conditions above to choose a cautious next step. A symptom alone never proves that the appliance has failed.
Resolve it without buying anything
Complete the 3 user-accessible checks in order. If normal operation returns and no warning sign remains, no replacement is indicated.
Replace only the confirmed part
If the checks isolate a worn or blocked component, match its complete reference to the exact appliance model before ordering.
This guide does not identify a replacement part. Do not order a generic component from the symptom alone.
Arrange a diagnosis before replacing the appliance
Stop at any warning sign listed above. A qualified diagnosis should confirm that repair is unsafe, unavailable or uneconomical before an appliance replacement is considered.
