Why does my electric underblanket still not heat after I wash it?

If the blanket stopped working after washing, the most likely cause is that it was not fully dry or the controller was not reconnected correctly. The manuals state that the blanket can be machine washed, but the controller must be removed and the blanket must be dried naturally before use. fileciteturn0file2turn0file1turn0file10

1. Check that the blanket is completely dry. Expected result: any remaining moisture can stop safe heating and may cause damage if powered on too soon.
2. Confirm that the controller has been reattached correctly before plugging in the blanket. Expected result: the product should not heat if the connector is not seated properly.
3. Look for twisted fabric, compressed seams or a blanket that dried folded. Expected result: flatten the blanket and remove creases before the next test.
4. Make sure no cleaning product or heavy detergent residue remains in the fabric. Expected result: residue can leave odour or affect performance after washing.
5. If the blanket still does not heat after drying and reconnecting correctly, stop using it. Expected result: a post-wash failure can indicate internal damage that should not be ignored.

Do not use the blanket if it smells damp, looks warped, shows discolouration or if the controller has been exposed to moisture. If the issue remains unresolved or safe use is uncertain, contact the retailer or store where it was purchased. fileciteturn0file1turn0file2turn0file11
