Dishwasher will not intake water

Your post is a little confusing but I'll try my best.
First, it sounds like you fixed the sink problem and now have a dishwasher problem related to the backup.

I would take the drain line off both the sink and the dishwasher and clear anything that got stuck in there while fixing the main sink drain. It could have had something plugged into it by using a plunger on the sink.

If you have any standing water in the dishwasher, pushing the cancel button should activate the water pump and you should see the water drain into the insinkerator, etc whilst hearing the pump. If you hear the pump and see no water draining but still have water in the dishwasher, you have a clogged line. If you don't hear the pump, your pump might not be working or the cancel does not activate the pump.

Two things to consider....clean water or dirty water?

Clean water usually indicates the fill valve is not shutting off all the way and the fill valve is "weeping" water in all the time = new fill valve time!!

Dirty water usually is not a dishwasher problem but more of a plumbing issue. Often the sink drain that carries the sinks water outside is not fast enough and some of this sink water is backing up into the drain hose and filling up the dishwasher through the drain hose. The drain from the sink to outside needs attention as this type of a problem indicates a slow house drain for that sink.

The dishwasher drain line should be clamped to the top underneath part of the counter before entering the sink drain plumbing, this may help the water from coming back inside the dishwasher.

There can be multiple reasons why the water is not entering the line. First thing to do is to disconnect both hoses from the dishwasher and place them in the sink. Turn on the water slowly and make sure that both hoses release water into the sink. If the water flows, get a plastic drain snake and attempt to push it into the water intake lines from the rear of the dishwasher to clear any clogs that may be in the lines. Look at the rotary head in the dishwasher for hole clogs and remove any debris found. Reconnect the water lines and make sure that all inlet valves are open. Turn on the water and attempt the fill again. If this does not work, then you will have to disassemble the rear panel of the dishwasher and look closer at all waterline connections.

The drain hose going to the kitchen sink is blocked. If you have an insinkerator in your kitchen sink then run it first. Otherwise take the dishwasher hose out from the sink outlet and run straight into sink to see if any difference.

It's a drain clog within the disposal. Try a drain cleaner, if no luck, you will likely need to replace it.

See if the float in the front corner inside the unit moves up and down freely and makes a "clicking" sound when moved. If there is a clicking noise, the float switch is probably okay. The switch can be tested with a volt/ohm meter by removing the lower access panel to get to the switch. Some units have an actual water level pressure switch attached to the pump housing instead of a float and switch. These switches can plug up with soap residue causing a no fill or overfill condition.

The problem is more likely the water inlet valve. These valves go bad frequently for a variety of reasons. It is not worth the risk of a valve failure and possible flood to take apart and clean an inlet valve. Replacement is the best solution. In most conditions, the inlet valve will need to be replaced every 4-6 years.

If the solenoid valve is humming and calling for water, you probably have a plugged screen in the valve, some you can get to and clean, some you have to replace.

Hi,

Here is a tip that I wrote that will help you with your dishwasher not draining problem...

Dishwasher Problems - Water will not drain out

heatman101

it should tighten when you turn the water on ?

Try turning water off to dishwasher and see if it stops it. If so, replace valve. If not check for a low drain hose loop, allowing drain water from sink to back up into dishwasher. Just raise drain hose as high as possible under sink and secure.
