Samsung wdo804w8ei/xeu not drying

After replacing the three way valve on this machine , at the end of the drying cycle , the clothes are coming out hot and wet . We have checked , cleaned and double checked the condenser unit , the machine is draining properly , heating properly so we have checked the obvious . The replacement valve ordered was an LG valve as it was a suggested alternative for the original and was cheaper . . We have tested the flow of water when on the drying cycle and it seems to be flowing way too quickly for the trickle needed for condensation . Suspecting the restriction in the valve outlet to be wrong , we ordered the genuine Samsung valve , and it has come through to be identical to the one we have already fitted . ( same restrictor ) . Unfortunately as we replaced the valve for a cut and dried “filling when off ” fault , we no longer have the original valve to look at the restrictor .Wondering if anyone can shed any light on this for us ?
