No. A damaged cable needs appropriate assessment and repair before use. Tape or positioning the cable so the damage is less visible does not restore its safety.
Understanding this situation
Avoid touching exposed conductors or stretching behind the machine to inspect inaccessible damage. A cable trapped under an appliance or cut by a cabinet edge may also indicate an access or positioning problem that needs attention.
A useful next step
Keep the appliance unused and isolate safely where possible. Describe the visible damage and how it occurred. Do not fit an improvised connector, shorten the lead or substitute a cable solely because it appears similar.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
