Flashing lights on Hoover VHD 8KG 1200 washing machine?

the time saver button and the 1000 (spin) lights flash 16 times with a long pause after...what does this mean?? It has previously flashed 3 times and have been told this was a drainage or pump fault. This time I have checked and cleaned out the filter, pulled the machine forward a bit to make sure the pipes are free and cheked the outside drain is not blocked. Please help
