When to stop

Smoke, a burning smell, damaged wiring, standing water near power, or an active leak: stop using the appliance. Disconnect power only from a safe, dry location and arrange qualified service.
Stop if a part is damaged, jammed, sharp, inaccessible, or does not match your manual. Do not force parts or remove a cabinet panel.
