Firstly you need to establish the cause of the problem starting with some.
Water supply to dishwasher not working.
To check the float unplug the dishwasher and remove the lower rack and the float assembly cover.
If you have your dishwasher connected to the cold water supply then it s highly likely that a faulty heating element or thermostat are the cause of the water not heating.
Confirm that your water supply to the appliance is turned on and there are no leaks between the supply and the dishwasher.
Dishwashers not filling with water.
If the float is stuck this could be the reason why your dishwasher won t fill.
Check filter and flood float the flood float keeps the dishwasher from overfilling with water.
If it was turned off for any reason and mistakenly left off the dishwasher cannot fill with water even though the unit comes on.
If your dishwasher is not filling with water there are a few easy things you can do to resolve this issue.
Many dishwasher problems can be repaired simply by replacing parts or even just cleaning the appliance properly.
If your dishwasher won t fill with water the problem may be a bad water inlet valve.

If you re connecting to hot then it s worth checking the water supply to check that there is actually an issue with the dishwasher and not elsewhere.
1 dishwasher does not work at all 2 motor whines but dishwasher does not start 3 dishwasher does.
A dishwasher failing to fill with water is a fairly common fault and can be caused by a variety of problems ranging from the obvious to the obscure.
Check the water supply feed line underneath the sink.
Whilst you might need a professional repair you can most likely fix this problem yourself.
The float rises when water fills your dishwasher and once it reaches a pre set level the water switches off.
