If your dishwasher won’t fill with water, it doesn’t necessarily need to be repaired or replaced—you’ll be pleased to know that with a bit of hard work and elbow grease, you should be able to get your dishwasher working and your dishes clean again.
How to repair a dishwasher if it isn’t getting any water
Is there standing water in the dishwasher?
Many dishwashers will stop filling with water when their drain is clogged. The appliance has sensors that check if there is any water present in the drain and that prevent the hose jets from operating if there is. Try to clean any debris out of your drain to get the water flowing again—you may need to use specialised cleaning materials.
Check the float valve
The float valve is located at the bottom of the dishwasher. This rises when water fills the appliance and cuts off the water when it reaches a certain height—just like the float valve in a toilet cistern.
Occasionally, this valve can become stuck in the upright position. Take the lower racks out of your dishwasher, locate your float valve, and see if it moves up and down freely. If it does not, you may have to clean it or replace it.
Check the water supply
Your water supply may simply no longer feed the dishwasher properly. For instance, the line that leads from the water supply line to the appliance may be bent or kinked; if this is the case, just straighten it out or buy a new one if it is badly damaged.
Check the valves
Look at the valves that connect to your water supply line. If you can’t see any kinks in the hoses, one of these valves may be shut off or damaged. Check the hot water valve, which is usually under the sink, and ensure that it is fully opened.
Next, check the water inlet valve, which is where the hose meets the dishwasher. Turn off the water supply to the dishwasher, put a saucepan or a bucket underneath the hoses, and unplug them. Carefully unscrew the valve and look at the filter screen behind it – if it is dirty, give it a clean.
Check the door
If the door is not registered as closed, then the dishwasher will not fill up. Take a close look at the door and make sure it is latching and locking properly.
If you have still been unable to fix the problem, you’ll need the help of a professional appliance technician. Get a repair from us or take out an extended appliance warranty for an outstanding level of protection.
