Just sorted problem it was a jammed emptying pump probably caused through not being used while away for 3 months it is easy to do with machine upside down 
 x 1 st screw then twist pump, bayonet type fitting . then turn impeller with end of screwdriver reassemble dont forget the  st screw to stop bayonet undoing.    Brian Atkinson
