The front panel containing the mesh can be removed from the body of the speaker. See the replacement guides for more information. From there, the mesh can be cleaned using a fine-bristle brush and a compressed air cleaner if needed. If the problem persists, small amounts of water can be used to scrub with the brush. Avoid completely saturating the mesh, and use water conservatively. Make sure the mesh is completely dry before re-attaching it to the rest of the SoundTouch 10 body. The moisture may be harmful to the electronic components found inside the device.
This may be because the cable itself has been damaged or frayed. Inspect the cable for any signs of wear. Also try connecting the charging cable and speaker to a different outlet to ensure that it is either the speaker or the cable that are the problem. Also check the cable port on the speaker for any dirt or lint that may be trapped inside and preventing power from reaching the speaker. The port can be cleaned with a compressed air duster if this is the problem. If all else fails, the charging port itself may be damaged and need replacement. For more information, see the Troubleshooting Guide.
