Check out simple things first: Look at the carbon brushes in the motor. Theyre graphite blocks which transfer mains power to the copper segments of the motor. v. cheap parts and easy to replace. Look at the copper segments to check for burning or pitting.
Check the filter unit for blockages.
Disconnect pump from sump hose and check for obstruction in either item.
Locate the pressure switch - a round item about 3 inches across. Its an air operated switch which tells the machine water has reached the correct level. Disconnect the rubber pipe from the switch and blow down through it to clear any blockage. Switch itself may be faulty.
