HI In most dishwashers, the water pump is located under the lower sprayer arm. This component pumps the water through the dishwasher. The pump has two impellers, top and bottom. These, as well as other components, can become clogged with food or detergent. Here's how to disassemble the pump:

Step 1: Remove the cap that holds the sprayer arm on.

Step 2: Remove the sprayer arm, the screen, the pump housing, a bolt, the upper impeller, the food disposer blade, a spacer plate, the impeller hood, a flat plate, an O-ring, and the lower impeller. Lay the parts out in order as you disassemble them so that you'll be able to reassemble them properly.

Step 3: Clean the parts thoroughly with a mild detergent solution. If any parts are worn, replace them with new ones made for the dishwasher.

Step 4: Replace any seals, such as the O-ring or other washers, with new ones.

Step 5: Reassemble the pump, keeping the parts in order.

To reach the water pump, remove the sprayer arm and screen and then the pump housing. Remove the bolt, and the pump components can be disassembled.

On some dishwashers, the lower impeller serves as a drain pump. This type of system usually has a reversible motor; machines with nonreversible motors have drain valves, as detailed previously. If your machine possesses this impeller pump system, and the water will not drain from the dishwasher, clean the lower pump impeller. This may solve the problem. Otherwise, call a professional service person.

Water wont drain


John make sure the drain line under the sink and unit haven't been pinched from stuff under the sink in particular. Check where the drain hose attaches to drain under sink and take it off and make sure it's clear. It is one of the most common areas where the drain hose gets clogged at the connection or in line at a sharp kink in the hose. If the unit is not running then the problem is there and if the unit makes no noise when in pump mode you should be able to tell. That could indicate a bad pump or switching issue from clean to empty. Now for the occasional weird things that happen. In the bottom of the dishwasher is a screen of sorts that keeps large objects from getting into the pump. I have on occasion found that screen so full of food particles that the water can't get to the pump. Most dishwashers have a mulching type unit on the pump to help chop food up but if the stuff can't get to it, it clogs. I know of 2 units that ruined the pump from running them dry and in both, food clog was the problem. The screen is readily accessible and a semi- soft brush and hot water should clear it. The reason this happens is the food gets baked on the screen when the unit goes into dry mode. Like I said it's not real common but if all else says the unit should empty, check this.

Samsung new dishwasher will not run through a cycle or drain properly. Water left in bottom. Keeps stopping and going to quick flashing.


The drain hose from the dishwasher may be partially or fully clogged with food stuffs like peas, corn, green beans, or other foods. disconnect the drain hose and clear debris from drain hose and run threw drain cycle.

I have a Matsui MF2W dishwasher that will not drain. Theres always water in the bottom. The exit tube rises to the pipe at a height of 90cm which is < 100cm as ststed in the manual Could it be blocked?...


Hi
Dishwasher not draining issue usually occurs due to kinked drain pipe, clogged drain filter or drain pump. First make sure that the drain is not clogged and remove clogs if present. If no visible lint is present then remove the lower front access panel to check the drain filter and drain pump for any clogs, you'll need to clean the drain filter and drain pump completely. Also, check for any food pieces stuck near the pump impeller & clean the chopper assembly. Please note that dishwashers don't drain out the complete water such that heating element doesn't overheat. Hope this helps... Please post back for any further assistance.

Water standing in bottom after cycle complete


Either your drain filter is clogged, or you're having drainage problems in the line. My first step would be to take apart the bottom of the dishwasher according to the manual and making sure there isn't any food stuck in the bottom drain. I had to do this about a month ago to get some spaghetti out, it's not very difficult, just be careful not to drop any screws.

There is water in built in dishwasher when cycle is done.when you open door it runs out and rest remains in bottom of dish washer about an inch and a half of water.


The drain hose is supposed to go from the garbage disposal to a high point under the sink in back to keep the water from gravity draining into the dishwasher when it shuts off. If you look you will see that the hose is laying on the bottom of the sink cabinet. Get a hook and wire it up so you're not washing dishes with water from the disposer. Be sure to run the disposer. if it is clogged with food the dishwasher will not drain, water will back up and drain back into the dishwasher. Also make sure that the pipe exiting the disposer isn't clogged and draining slowly. hhe best solution is to have an air gap that mounts on the sink. It goes between the washer and the disposer to keep this from happening.

Water standing in Dishwasher


Hello buzzy220,
If you have water remaining in the bottom of your dishwasher then I would check the following:
  1. The drain filter screen is free from food byproducts that might limit drainage.
  2. The drain line exiting the dishwasher itself.. is it kinked or clogged?
  3. If your drain line is plumbed into a garbage disposal side entry, is that clogged or your house drain clogged?
  4. Is your dishwasher pump contaminated with sediment or anything that would limit its ability to pump?
  5. Are the water lines that come into or out of the pump blocked, damaged or restricting water flow?
Those are the main reasons areas of concern to investigate.. BTW, your drain line exitting the dishwasher should be routed up high and down into your sink drain system or thru the garbage disposal tap so that you have an air gap as 20YRSEXP was inquiring about..

You can run a simple test to verify all this..
Detach your drain hose from the house drain system ( from the garbage disposer or sink drain.. then route that into a rubber barrel ( be sure to keep part of the house up around the height of the countertop when you do this.. )... You should see a fairly robust flow of drain water into it when the system functions properly.. I would encourage you to run this test with no dishes inside it,.. This test will tell you if the restriction is in the dishwasher or house drain side..
Hope this helps you..
Regards,
Rick
