An appliance problem starting right after a house move, a new detergent or additive, or a water/gas/power supply change should be checked against that specific change first. For cordless-vacuum battery and charger, first cool to room temperature, use specified charger and compare low/max mode without head.

ReversibleNote exactly what changed — installation, supply type or product used — and confirm it worked immediately before. Expected behavior: accept charge and deliver expected runtime without heat or swelling.
Isolate the component boundary
ReversibleCool to room temperature, use specified charger and compare low/max mode without head. Test with the previous product or a factory-recommended one, or verify the new supply connection matches the appliance's requirements. Boundary to separate: battery versus charger, contacts, temperature, mode and powered attachment.
Correct only the proven cause
ReversibleReplace the proven charger/battery through approved service. Correct the installation, switch back to a compatible product, or arrange service for a supply mismatch that cannot be user-corrected.
Verify and stop safely
ReversibleRun one complete normal cycle under the new conditions and confirm normal results. Stop for swelling, heat, odor, liquid or damaged contacts.
