Cold water will not stop filling during rinse
while the unit is filling in the warm cycle. reach behind and shut off the hot water tap.I bet the water flow stops filling, if so, you would need to change the inlet valve on the machine. You see, in warm, if the cold is not filling, you still hear the hot filling and the unit will advance. The rinse cycles are mostly "cold" only. if the valve is not opening it will not allow it to advance from the rinse section on the board.
