Why won't the brake release the drum (tub) in my Simpson 950 Eziset?
I have been unsuccessfully trying to solve a problem involving the brake/clutch on my Simspon Ezi set 750. So my hours are not totally lost I can report the sequence of events that happen during the wash in case this helps someone fix their machine. The click at the start is the cable solenoid retracting and disengaging the brake which then allows a few seconds of spin cycle which continues in bursts for about 1 min ( Presumably to allow the water to spray evenly over the detergent on the top or just wet the clothes ) . After this the cable retracts( Is loose) and the tub brake lever is engaged although ( And this is my issue) I think the pawl clutches'  purpose is to stop the bowl from rotating to the lock position as this locks the agitator and the bowl as one and is really only useful when the spin cycle is finished. My clutch doesn't seem to work properly and the agitator and tub lock together after the initial spin so there is no agitation and excessive motor load. 
Perhaps this might assist someone, although Simpson is generally found in Australia and New Zealand.
