Try to look under the machine when it is spinning. Use a torch & see if you can pinpoint where the water drips from. It will either be the drain pump at the rear or the hose from the tub down to the drain pump or spraying off the drive pulley & running down the cabinet wall. If it is coming through the drive pulley it will be because the main seal in the outer tub needs replacing and also the bearings. That is a major job which can only be done after dismantling the entire inner & outer tubs from the cabinet.
