Possible Causes

How to Fix / Troubleshooting
Safety first: Remove the battery before opening the handle.
- Step 1 – Confirm symptom: While the vacuum is running, gently move the handle (do not open it yet). If it cuts out, the handle wiring or switch is suspect.
- Step 2 – Open handle: Remove screws and carefully separate the handle halves. Note the position of buttons and springs.
- Step 3 – Inspect switch: Check the main power switch for signs of wear, discoloration, or loose mounting. Resolder any cracked joints on the PCB.
- Step 4 – Clean contacts: If accessible, use contact cleaner on the switch (with power disconnected) and operate it several times.
- Step 5 – Replace switch or handle PCB: If cleaning does not help, replace the switch or the entire handle PCB assembly with the correct Clatronic spare.
