Removing and re-fitting the drain pump is quite easy
• switch off the power
• tilt the machine back so that you can see the pump
• remove the plastic panel at the bottom of the machine held in by 1 torque screw (requires a t20 torque screwdriver)
• then undo the torque screw holding the pump
• you can then remove the electrical connector
• then you can remove the two spring clips with your pliers
refitting is the reverse.... check for leaks.... job done.... best of luck
