For an 18 year old W842 (which is similiar), 'Rinse Light' means the EL200 PCB ( Main Controller Board ) has become faulty , due to either the Motor becoming faulty ( to check , examine the resistance on the Armature(10.5 ohms approx ) / the resistance on the Field coils (6 ohms ) / the resistance on the Tacho Coil (319 ohms) , all these are approx values . If all Ok ,then replace the motor brushes ( £5.99 on ebay) . After ruling out the motor , replace the two shock-absorber struts , attached to the bottom of the drum ( £15 ebay ), which have caused the problem ....... by letting the drum hit the side and back of the washing machine unit whilst in the spin cycle .
Remove the PCB for repair ( approx £30 on ebay) . Note the control knob pulls off , and the hose pulls out of the back of the pcb. A new board scraps the machine at £360 .
Hope this helps someone ........ saved me the £700 for a new machine, and many thanks to others who have posted on the internet re this subject.
