Beko Wmb81445Lw Clothes Still Wet After Spin

1400 spin should be perfectly good at spin drying laundry although some washers may well be better than others even with the same spin speed. The only things that are likely to reduce spin drying performance are if there was some partial blockage somewhere reducing the flow of water out from the pump just enough to cause problems such as in the plastic spigot between the drain hose and the u-bend. Hotpoint washing machines used to do that because they had a hidden filter inside the sump hose leading to the pump which became bunged up with lint.

Another possible issue could be if the washer isn't balancing the loads properly, which can stop it reaching full speed or cause it to reduce the time it spins. However it shouldn't cause problems every time unless you somehow put bad loads in all the time. Just check this article in case - Loading a washing machine
