I have encountered a similar problem. The following lights were flashing on and off:
- Reduced creases.
- Mini Load.
I also found that previously one of the 'lifters' inside the drum had broken off and someone had tried to put it back in place and continued to use the washing machine. After a short period of time the above mentioned flashing lights began.
I first suspected the pump, but this was fine. I then disconnected the hose which connects the hole from the drum to the pump and I found a child's sock blocking the hose. I removed the obstruction, put it back together and the machine worked perfectly. I also replaced the lifter (apparently these break quite often) and the machine has been working perfectly ever since that day.
I hope this helps. Good luck.
