I had a similar problem. The machine started to fill, then after about 1 minute emptied with 2 flashing lights.
I fixed it. Try this simple thing first. Costs about 5 minutes of your time.
Mine was a water level sensor problem.
Empty the machine, Unplug the machne, remove the top (2 screws at the back and slide top backwards. The level sensor is located about half way along the left side near the top. There is a clear plastic tube connected to it and a connector with 4 wires. The sensor can be pulled off the plastic retaining clip.
Remove the plastic tube (use a pair of pliers to slide the circlip off). Remove the 4 wire connector. Gently blow into the sensor where the tube was and you should hear the sensor switch click. Normally there is contact between pins 1&3, with pressure this changes to pins 2&3. All mine needed was to remove the tube and replace it again to reset the tube pressure to normal. Replace all as found and try again. Mine has worked fine since.
