Dishwasher Won’t Fill With Water

Does your dishwasher refuse to fill with water?

Most of the time, when the dishwasher won’t fill, it is caused by a broken dishwasher, but often the “no water” issue is caused by a simple problem, that you yourself can resolve.

Is The Water Turned On?

The first, and most obvious thing to check is, are you even getting water out of your house plumbing? You can start by finding the water valve to your dishwasher fill line, and making sure it is turned on all the way. The most common water valve type to a dishwasher is the screw in and out, oval shaped handle valve. The other common valve type, is the 90 degree shut off valve, which will have a little knob, or a longer handle, that you twist 90 degrees, to turn the valve on or off.

The oval handle valves, must be turn counter-clockwise, if you want to turn them on, and they must be turned clockwise if you want to turn them off. Be careful with these types of valves, as they are usually built cheaply. These valves tend to stick open, and many times, are very difficult to twist shut. You can easily break the handle trying to shut one of these valves off, as the handles are often made out of plastic, or thin metal. This type of water valve is also notorious for not shutting off all the way, even when it is screwed all the way shut. These “oval handled valves” may drip, or ooze water. . . . even when they are off all the way!

The 90 degree shut-off valves are built much better. They shut of quickly, and don’t bind. Their handles don’t break during normal use, and they don’t drip, or ooze water when they are shut off! We highly recommend installing these valves any time you need to replace a valve.

Is The Fill Hose Kinked Or Broken?

Follow the hose from the valve to the dishwasher, and make sure that it has not been kinked, or pinched buy a door or heavy object. Also make sure the hose is not broken and spraying water throughout your house. If the house is broken you will probably know, as your house will be severely flooded. Rubber fill hoses can crack and bulge with age. It is always a good idea to replace the rubber fill hose to your dishwasher every five years, to help prevent leaks or floods.

Frozen Water Line?

In the winter time, we always see frozen water lines to dishwashers. If you suddenly get no water during extreme, cold weather, make sure your fill line is not frozen. Houses have many constructions holes hidden behind the finished construction, and this can allow for cold air to flow between walls, floors, and cabinets. This cold air can find its way to a dishwasher fill line. Sometimes the freezing air will get to components inside the dishwasher, freezing the water that is always present in these parts. When the water inside these parts freezes, it expands, and cracks them. Then when the frozen water melts, it gives way to water pressure, and you have an expensive house flood, with extensive water damage.

While we see only a few cracked dishwasher components during normally cold years, we do see many more cracked parts during extremely cold weather. If you lose water during a cold spell, it is best to have a professional look over your dishwasher, so they can be sure that you will not have a flood on your hands when it all melts.

Is There a Water Float, and is it Stuck?

Many dishwashers have a water float dome on the inside, at the bottom of the dishwasher. This dome floats on the water, and when the water level gets high enough, the dome senses the high water level, and turns the water off. If this dome gets stuck in the “up” position, then it thinks the water level is high, and keeps the water off. This can be caused by many things, such as a piece of silverware falling down and getting stuck under the dome, or a piece of plastic wrap washing under the dome and staying there.

If your dishwasher has one of these floats, you can reach inside, and gently pull it up and down. It should move freely. If there is resistance, something is binding the float. If you don’t see anything obvious around the float, preventing it from moving freely, you should call an appliance repair service. Generally the domes are held in place by fragile parts, so it would be wise not to try and pull the float out until you know it is safe to do so.

Once you have verified that there are no kinks in your hose, the water is turned on, and your line is not frozen, the problem is most likely somewhere inside the dishwasher itself. At this point you should call a knowledgeable repair man, like the ones at Liberty Appliance Service.
