Model WA40J3000AW/A2 fills with water and then all of a sudden after about 5 mins. all LED's turn on - except Child Lock and Lid lock and Extra Large LED blinks. And it drains the tub. I hear an audible 4 beeps. I held the Temp button to troubleshoot - Extra Large blinks. So I replaced the valves. Still the same issue. I removed the hot water hose and the water was cold. According to the manual if it senses the water is not hot enough the machine won't start.
