The complete toy's instructions must permit the intended treatment. A washable outer fabric does not make an electronic sound module, battery or hidden component safe for a washer-dryer.
Understanding this situation
Some products permit removal of specific parts before washing but still prohibit tumble drying. Do not assume that an accessible battery compartment means all electronics can be detached safely or that every remaining material tolerates heat.
A useful next step
Follow the maker's exact preparation and drying method. Keep an uncertain toy out of the continuous programme. If electronics or a battery were accidentally processed, stop use of the affected product and seek its manufacturer's safety advice.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
