LG WD 8013F drains then won't spin

When I put the machine to rinse then spin or even for quick 30, it goes through its whole cycle, drains the water out and then stop everything skipping the spinning altogether. I have cleared the filter bottom left and still can't find anything. When it stops then prewash and timesave lights flash together. The manual says that this is a drain filter/hose clog. I've cleaned the drain filter and have checked the hoses that lead to it as best I can and find nothing.
