My LG Intellowasher dd wm-1480 FHD 7kg will not spin ?

Check the pressure switch -the system that determines correct water level in the drum. If its giving an incorrect indication to the program timer machine will either overfill, refuse to fill or refuse to spin. Its an air operated diaphragm switch triggered by rising air pressure induced by the entry of water into an airtight vessel attached to the base of the drum. It tells the program timer that the water has reached the correct level, allowing it to proceed to the next stage in the wash cycle. Power off, drag machine out onto the floor, remove back cover and top cover. The pressure switch is a round item about 3 inches across with several wires and a thin rubber pipe attached. It generally sits just under the top cover. Disconnect the thin rubber pipe from the switch and blow down through it to clear any blockage. Switch itself may be faulty but its more likely the pressure pipe or the vessel attached to the other end of the pipe is blocked. Remove the pressure vessel, put a small nut or screw in it, fill it with water and shake vigorously till any crud or residue is removed. Some machines have the pressure vessel integrated as part of the filter unit, with a pressure chamber moulded into the top of the filter body. Refit all parts, check that joints and connections are water tight.
Also check the filter itself - generally located behind a panel at the foot of the machine.Some are obvious like little square hatches and some are hidden behind the trim panel at the foot of the machine. Once panel is removed the filter should be visible. Its generally a circular plastic fitting which unscrews in an anticlockwise direction. Unscrew it and then give it a sharp tug towards you. If its stiff, grip it with a pair of pliers. Be prepared for some spillage. To refit, push in firmly till the threaded part engages and then tighten clockwise. Some hotpoint, indesit and ariston filters are located in the big black sump hose (the one that leaves the bottom of the outer drum and connects to the pump). Power off, drag machine out onto the floor, remove back cover or tip machine up at an angle. Locate sump hose, remove the tensioner clip by squeezing the tabs together with a large pair of pliers or vise grips, remove the hose, take out filter and clean. Be prepared for spillage of water. May help if the machine is tilted backwards at an angle.

Check out the carbon brushes in the motor. Theyre graphite blocks which transfer mains power to the copper segments of the motor -Theyre possibly worn down. They're quite cheap parts and easy to replace. The brushes are at the other end of the motor from the drive pulley. The holders are plastic or bakelite and are generally held in with screws or plastic clips.
There are generally 2 ways that motor brushes can be fitted
1) screwed onto the outside of the motor - undo the screw, remove the old brush, remove wire attached to brushes, screw the NEW ONE INTO PLACE and repeat for the remaining brush.When brushes are secure NOW is the time to RELEASE them free of the brush holders by bending back the tab on the side of the brush holder. Reattach both brush wires.
2) the brushes are fitted up a slot and held in with a plastic barb - Remove the brush wires with a short stubby screwdriver and a stiff piece of hooked wire. Insert the screwdriver up the slot and behind the plastic barb, press enough to make the barb clear the slot, holding it in this position hook the brush out. If stiff you can use a thin pair of long nosed pliers to pull out remove old brush. Insert the new brushes until the barb holds them in position. Free them from of the brush holders by bending back the tab on the side of the brush holder. Reattach both brush wires.
Also, look at the copper segments they run on to check for burning or pitting. If the segments are burnt or damaged you need a replacement motor or a replacement armature (motor part) if you can source one. Check the tacho coil for breakages in the connections. The tacho coil is a small generator coil on the end of the motor which provides a voltage proportional to the speed of the motor. This voltage is fed back to the speed control module to enable the machine to check the rotation, direction and speed of the motor.

Spin problems may also be caused if the machine reckons the load is out of balance, rearrange the load. If problem persists could possibly be a fault in the out of balance detector switch or the suspension and damping system.
