Firstly, it doesn't pump water in. It has an inlet valve which opens when power is supplied to it from the control board and allows water to flow in. So maybe you have a faulty inlet valve or the control board is not turning on the power to the valve. You need a multimeter and testing knowledge to find the fault. As for the other problems, have you tried pushing the reset button? If the dishwasher is so important then I suggest you call a service person to sort out the problems.
