Jim, that’s one of the new ones that has a flow sensor (impellor jug) on the side tank, position 0405 on the parts diagram. Have changed a couple of these, although may be just a poor connection. Could also be water in the base – usual suspect for leaks is the connection between the side tank and tub (round plastic vent towards rear). I usually take tank off, clean o’ring and refit with a smear of silicon sealant. Wiz
