My dishwasher does not sound

Question

My dishwasher does not sound correct (lack of spraying action sound) and this last time when I opened the door the soap had not disolved and the dishes where still dirty. I have taken apart the bottom arm before for a cleaning but it was only a couple of weeks ago. Could it clog up again so fast even when the type of dishes remain the same? Did I put it back together wrong? Maytag EQ Plus
