No water entering dishwasher - Zanussi 24 in. DA6141 Built-in Dishwasher

If there's no water entering your dishwasher, check these:

Water-inlet valve
Float switch
Water-inlet valve
The water-inlet valve lets water enter the machine. If this valve is defective, you need to completely
replace it. It's usually located behind the lower access panel on the left or right side. It's the device
with the main water line (usually copper) from the house, a rubber tube to the dishwasher, and two
wires attached to it.

Float switch
The float switch is a small electrical switch that's located right below the dishwasher "floor."
Above the switch, on the inside of the dishwasher, is a plastic cylinder that floats up as water fills
the dishwasher. If this switch is defective, or if the plastic float gets caught or trapped in the raised
position, the water can't enter the dishwasher. If the float switch is defective, you need to replace it.

I have a Siemens dishwasher SD561591GB/23 only 2yrs old which displays flashing water & rinse aid lights.The rest of the display is off and machine does not work.I've topped up the rinse aid and plugged it out and back on but no joy.Any ideas how to sort this.Cluade
