On a Miele Classic C1, a red indicator with a fresh bag and a lid that will not close both call for checking the exact bag, its holder and the airflow before forcing anything. Remove the plug, lift the bag by its collar and check that the holder is seated in its guides. Reinsert the correct bag until the collar reaches its stop. If the lid still meets resistance, remove the bag and inspect for a folded collar, obstruction or displaced holder; never use the lid as a lever. [object Object]

What the symptom may indicate
Checks in the right order
- Make the appliance safe
Switch off and unplug, or remove the battery only where the manual permits it. Keep water away from motors, contacts and non-washable filters.
- Run the official user check
unplug, check every airway, insert the exact bag until it clicks and never force the compartment lid
- Retest once and decide
separate a bag-indicator reading from a blocked airway, unsuitable dust load or incorrectly seated bag

- Stop for a burning smell, hot or damaged battery, liquid ingress, exposed wire or a fault that returns after one official retest.
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.
