Vacuum stops running and a solid red LED on the tool remains lit.

Safety first: Remove the battery before clearing blockages or opening the unit.

• 1. Empty dust canister: Remove the canister and empty it completely. Tap gently to dislodge compacted debris.
• 2. Clean or replace filter: Remove the main pleated filter or HEPA cartridge. Tap it outside to remove dust. If heavily clogged or damaged, replace with a genuine Milwaukee filter.
• 3. Check hose and tubes: Detach the flexible hose, wand, and floor nozzle. Look through each section for clogs (screws, drywall chunks, wood chips). Push out obstructions with a flexible rod.
• 4. Inspect motor inlet: With the canister off, look into the motor inlet for debris wrapped around the fan. Remove with long-nose pliers if accessible.
• 5. Cool-down period: Allow the vacuum to sit for 10–15 minutes to let the overload protector reset, then reinstall the battery and test.
• 6. Persistent overload: If the red LED returns quickly with clear airflow, the motor assembly may be failing and drawing too much current. Replace the motor/fan assembly.
