When the blender is being used excessively, the blending lid will heat up due to the friction caused by spinning metal parts. When the “Blending lid too hot” error appears, the blender will not be able to initiate a new blend. It takes up to 10 minutes for the blending lid to cool down. The blending lid could also be substituted with a replacement lid and the blending continued as normal. Please note that keeping the lid in cold water will not speed up the process.
