Assembly is the reverse of disassembly. The following points are worth noting.
  • Drain Hose Outlet Elbow. Refit to the base. NB: Ensure the lugs on the elbow are located underneath the pump bracket. Clamp into position.
  • Pump. Turn the pump clockwise when refitting it into the bayonet fixture. Check that the locking tab has clicked into place.
  • Wiring. Fit the wiring harness into all the securing clips.  Check that the harness assembly is secured to the suspension rod.
  • Drain Hose. Unclip the drain hose fixture from the lip of the outer bowl and screw into position on the cabinet. Ensure the drain hose grommet is correctly fitted.
  • Topdeck. Before refitting topdeck ensure that reed switch harness (phase 2-5) is tightly secured.  When refitting top deck ensure that OOB lever does not catch or sit on neck ring.
  • Base panel: Ensure locating tags are straight before refitting.
  • Pressure Hose. CHECK THAT THE LOOM AND PRESSURE TUBE ARE NOT KINKED or close to wrapper before refitting the top deck. Blow down the pressure tube to check if it is clear of water droplets. Ensure that the nylon cord in the pressure tube does not obstruct when reconnecting tube.
  • Mixing Chamber. Phase 5 only. Ensure that thermistor or plug is correctly located.
  • Safety testing should be carried out in accordance with standard electrical testing procedures. The resistance from the earth contact on the mains lead to the wrapper should not exceed 0.5 ohms. The insulation resistance should also be measured at 500 volts DC between phase & neutral to earth. The maximum resistance should not exceed 1Mohm.
Test Smartdrive by filling (using both valves), draining and spinning to 1000 RPM.  Open lid when at 1000 RPM.  Check the size and the operation of the Out of Balance lever.



MOTOR ASSEMBLY AND DISASSEMBLY

  •  Remove the rotor by using a 16mm or 5/8" socket. Lift the rotor clear, and place in a plastic bag. The rotor has strong magnets and can attract metal objects. If any foreign objects are caught in the rotor area these may cause the magnets to wear and create a fine black powder which will permeate through the whole appliance.
  • Unscrew the 4 bolts securing the stator to the outer bowl using a 3/8" socket.
  • Lift the stator clear of the shaft, turn over.

NB: When placing the stator on a work bench, ensure the RPS connectors are facing upwards or damage can result. Do not place the stator inside the rotor.


ASSEMBLY
  • Wire up stator before locating stator into position.  CHECK Red Blue & yellow wiring is correct.
  • Grease the stator side of the clamp plates and the inside section of the stator that fits over the bearing.  Fit the clamp plate and spacer assembly to the back of the stator. Locate the stator into position. It will only fit in one position.
  • Refit the clamp plate onto the stator and tighten the four 3/8" bolts to a torque of 5 Nm.
NB: The stator should have a slight radial movement of approximately 0.5 - 1mm when correctly tightened and should have maximum axial play (rocking movement) of 0.5mm.
  • Fit the wiring harness into the securing clips.
  • Fit the rotor onto the shaft and locate on the spline. Using a 16mm socket, tighten the plastic nut to a torque of 16 Nm. Hold the rotor stationary until it is secured.
