Ok Tom lets start again, this should go fairly quickly since this is a common problem.
Pull the machine out from the wall then remove the vent, try a load of clothes on a 30 minute cycle, if there is no improvement then take the panel off in the rear, next pull the filter out from the top of the machine, Remove the screws from under the filter then go around back and take the 4 screws out on the lower half of the lint filter chute. Pull the chute (tube right out of the machine and clean inside the chute. Next put it all back together and try the machine. If this clears the problem up great! If not your problem will be the 2 coils on top of the valve, they are shorting as voltage is being applied and not opening the valve.
I forgot to mention once the vent at the rear is taken off and you try a load if the unit does begin to work correctly you have a blockage in the vent between the machine and the outside of the house.
