OK when it is in mid cycle can you hear the circulating pump (that is what supplies the water to the spray bars) running quickly or is it noisy ? Secondly if you take the filters out do the spray bars rotate faster?
OK in that case you have only a couple of things that can cause this, the first one and most likely is that the pump impeller (propeller) has come off the end of the motor and whilst the motor is running the impeller is not going around, the only other thing is a blockage or obstruction. I'm afraid it a take out of the cabinet, base off and have a look time.
