https://www.repairclinic.com/RepairHelp/How-To-Fix-A-Dishwasher/36-160--/Samsung-Dishwasher-Overflowing

try removing spray spinner and clean out holes the spray heads get blocked and stop water flow, or you may be able to remove spray nozzles and clean out , i had this several times in the past also make sure the base drain filter is clean some times the small holes in the filter get smaller and smaller reducing water flow
hope this is of some help good luck

Hello

As water is filling your dishwasher, a float rises along with it. When the float reaches a predetermined level, it shuts off the flow of water, thereby preventing a leak. Sometimes the float can get stuck in the wrong position in your dishwasher, and it can prevent your dishwasher from filling. Check your float assembly. Replace it if you need to.

Water Inlet Valve

Your dishwasher may not be filling with water simply because the water valve's filter screens are dirty and debris-filled. Gain access to your water inlet valve and try cleaning it out. This might be enough to solve the problem.


Your dishwasher's drain valve is regulated by a drain solenoid. If the solenoid is malfunctioning, it may not allow the drain valve to funtion properly, which in turn could be the reason your dishwasher is not filling with water. Investigate your drain valve and test the solenoid. If the solenoid is faulty, replace it.

This is caused by the impeller being clogged or the pump is failing, When the pump is woring properly the water will shoot out with force.

Hi


Thanks for using FixYa. Check the water temperature by using a thermometer inside the dishwasher to measure the water temp. It should be as close to 125 degree F to 140 degree F as possible.

This would have happened as the dishwasher was overloaded with more than prescribed number of dishes. Check the spray arm and pump cover for splits or leaks. As the dishwasher is not draining properly, this issue is related to kinked hoses, knocked out disposer unit (if connected with the dishwasher drain hose) & clogged drain pump & filter.

Also note that dishwashers do not drain completely after a finished cycle and this is normal. Dishwashers are designed to leave some water in the unit to ensure that the heating element doesn’t overheat. If you suddenly begin to experience a large amount of water being retained in your dishwasher, you have a problem. Some of the most common reasons include that the drain hose isn’t working properly, the drain pump isn’t working correctly, or possibly there is a plumbing problem in your home’s drain lines. If you have checked the air gap and the drain hose and can’t locate the problem, then it is an issue with the drain pump of the dishwasher.

Please do accept the solution if the issue is resolved or else revert for further assistance.

Make sure that the spray bar when lifted by the water pressure is NOT hitting the dish rack OR has excessive friction. Test by manually lifting and turning.

Also the jets must exit at an angle to provide the torque.

If the machine functions properly when you add water, then it is likely there is a problem with the water supply. Start at the valve under the kitchen sink.
First I would turn that valve off and remove the water line. Then turn the valve on slowly. Use a small bucket or a large cup to catch the water. You should also have a lot of towels on hand.
If you are not getting much water through it, you may need to change that valve. If you are getting a good flow of water through it, inspect the water line checking for crimped or crushed parts. (is the line copper? braided steel?)
Reconnect the water line to the valve and disconnect it at the dishwasher. Now flush water through the line. how is the flow?
Lastly inspect the water inlet valve on the machine. I found a walkthrough for that at http://www.easyapplianceparts.com/repair.aspx?appliance=dishwasher&part=dishwasher-wont-fill
Actually, you might want to check that first. It may be as easy as cleaning a screen. I'm a plumber, not an appliance tech, so I tend to take a global approach to water supply.
Best of luck

There may be a couple of solutions to your problem. First, if you are not rinsing the dishes thoroughly before loading, your sump area in the bottom of the machine will get clogged, thus preventing enough velocity to reach top rack. Second, and most likely, your water inlet valve (or solenoid valve) is restricting. You have a timed fill mode through the timer and if the valve is not opening fully, you do not get the proper rate of flow into the machine. Replace the valve and your problem will most likely be solved.

check to see if your dishwasher is level. If it is unlevel the water could run to the front. Hope this helps.

suspect not draining properly all the time. if plumbed into the trap under the sink, then check there is no blockage there. (quite common) . hold drain pump into a bucket so you can see the rate of flow. hold the bucket about 3ft off the floor. if poor flow, then you either have a blockage at the pump or the pump is faulty
