Do not put electrical items or battery-containing components in a dishwasher unless their manufacturer explicitly provides a permitted method for the specific removable part.
Understanding this situation
A washable-looking casing does not establish that internal electronics tolerate water, detergent or heat. Detaching a cable alone may not remove all sensitive or powered components.
A useful next step
Use the product's stated cleaning instructions. If an electronic item has accidentally been processed, stop using or charging it and seek appropriate manufacturer advice. Do not run another cycle to rinse it more thoroughly or use the dry stage to restore it.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
