3. Why does dishwasher have water at the bottom?

If the dishwasher is not draining properly this usually means a clog. There may be standing water that has built up in the bottom of the tub thus indicating a clog. To unclog a dishwasher and get it draining water again, try running the garbage disposal which shares the drain with the dishwasher. If the disposal is full of food particles it can stop the dishwasher from draining properly. If you recently replaced the garbage disposal, check the disposal for a knock out plug that needs to be removed so the dishwasher can drain.

4. Is the dishwasher drain hose bent?

Examine the drain hose that connects your dishwasher to the drain pipe below the sink. Make sure there are no restriction or kinks in the hose. There can be food particles or other items stuck in the hose. If you find the drain hose fraying or damaged in any way, remove and replace it.

5. Dishwasher has faulty check valve?

The check valve is just before the drain hose, underneath the dishwasher. The purpose of this valve is to allow water to drain but not come back into the dishwasher. Take off the drain hose from the dishwasher and inspect it for clogs. Make sure the valve is free of debris and opens properly.

6. Faulty drain pump on dishwasher?

If your dishwasher is still filling with water and there are no blockages in the drain system, the pump may need to be replaced. Test the drain pump with a multi-meter to be sure it is working properly.

Water is left in the dishwasher filter area?

The normal amount of standing water in the dishwasher filter region midway up the filter area is about half way up to the top of the filter area. When you empty your dishwasher filters for routine cleaning, you may notice this water. Water is kept in the area to keep the seals from drying up. When you begin your next cycle, a little amount of water is removed and replaced with fresh water. This is normal.
