The invention provides a washing machine drum liner, a washing machine and a drum fixing method. The drum liner comprises an embedded block and at least two filler blocks, and each filler block is provided with a support part matched with a clothes inlet of the washing machine, and a groove matched with a balance ring. The grooves in the filler block are matched with the balance rings on the drum to fix the drum, and a hanging rod will not be drawn by tension of an external drum part by lifting the filler blocks up to lift up the drum upwards, so that damage to the washing machine during transport is avoided. As the support parts of the filler blocks are matched with the clothes inlet of the washing machine and the filler blocks are extruded horizontally through the embedded block, the filler blocks can contact with the balance rings and the clothes inlet of the washing machine more closely, the drum can be fixed. The drum fixing method reduces parts for fixing and fixing cost and improves transport quality.
