No water coming in after sink blockage

You should contact a maintenance expert

Unfortunately this sounds like more than a blockage. If this was a blockage water would not drain, maybe fill in sink or dishwasher etc. If water is coming from walls probably means it is leaking from drain pipe in the wall. Which would mean opening wall to find leak.

We had this problem and found out that the pipe leading away from the house was clogged. Have a plumber look (with a camera) down your clean out, and see if that is the problem. They can snake it from the clean out and clear out tree roots or whatever is the problem.

Is there a chance the plumber turned off the inlet water connection under the kitchen sink when clearing the drain?

Problems associated with water from the kitchen sink back filling into the dishwasher are caused by the drain line on the dishwasher not having a high end loop. In simple terms, the dishwasher line is too low and is providing a path for the water to flow in the wrong direction. Reposition the drain line so that it loops just above the sink drain. Then, anchor it to the wall so that it does not move. This will provide and air gap and creates just enough resistance to keep the sink water from entering the dishwasher.

NOTE: If you are experiencing problems with the sink draining as well, then you may have a plumbing releated issue.

Have installer come back to you, sounds like a pump problem, blockage, timer, ...is outlet hose kinked at all? It usually goes into the kitchen sink drain below.

• Some water, usually one to two cups, remaining in the bottom of the tub is normal. However, if water is covering the bottom of the tub, the dishwasher is not draining properly.
  
  
• Check for paper or large objects covering or blocking the sump area in the rear of the tub.
  
  
• Make sure that the right type and amount of detergent is used: Using the wrong type or too much detergent can cause sudsing that can prevent the dishwasher from draining. Only detergent specifically designed for automatic dishwashers such as Electrasol®, Cascade® or Cascade Complete® should be used. If you find suds in the dishwasher.
  
  
• Check disposer plug. If a garbage disposer has been recently installed, it is possible the disposer drain plug was not removed. The drain plug is a plastic piece in the disposer that blocks the hole where the dishwasher hose connects.
  
  Please consult the Owner's Manual. Download a free copy of the Owners Manual and/or Installation Instructions. In the Installation Instructions, will be the procedure for removal of the drain plug. You may also check with the installer.



• Be sure the kitchen sink drain is not clogged. The dishwasher typically drains into the kitchen sink drain or a garbage disposer. If the dishwasher drains into a garbage disposer, run the disposer to clear the drain system. Do not put hands into the garbage disposer. Serious injury could result. You should always turn on your garbage disposer prior to running the dishwasher to clean out any food or debris within the drain system.
  
  
• Check drain hose where it connects below the sink for blockage or a kink in the hose. New dishwashers come with a white corrugated drain hose, which should be used. Re-using old, worn out drain hoses may promote kinking and blockage. If it is neccessary to extend the length of the corrugated drain hose, be sure the total length does not exceed 120 inches and the extention used is not kinked or crushed. See your dishwasher installation instructions for details.
  
  
• Check the air gap if one is installed. It could be clogged. An air gap (not part of the dishwasher) is usually located on top of the sink. Some state or local plumbing codes require the use of an air gap between the built-in dishwasher and the drain system of the home. This plumbing device is used to prevent the possibility of back flow into the dishwasher in the event of a clogged drain system. This item is not a part of the dishwasher and, therefore, the dishwasher warranty does not cover costs related to cleaning or repairing a drain air gap.
  
  
Typical air gaps are easy to inspect and clean. Be sure the dishwasher latch is in the OFF position or unlatched prior to removal of the drain air gap cover. Simply lift off the cover (usually chrome, could plastic) and unscrew or unsnap (depending on type of air gap) the plastic cap below. Remove any material that may have accumulated and replace the plastic cap and chrome cover. This simple procedure should be followed any time the dishwasher fails to drain properly.

Sometimes perceived "no drain" problems are not "no drain" problems at all, but back flow of water from the sink or some other device into the dishwasher:


• If you notice dirty water building up over time in the bottom of the dishwasher and do not have an air gap, make sure you have a high drain loop. A high drain loop is created when the drain hose is makes a loop at least 18 inches above the floor. Usually this is accomplished by attaching the drain hose to the underside of the countertop. Without a high drain loop or air gap, dirty water from the sink can flow into the dishwasher. The high drain loop prevents back flow of water from the drain into the dishwasher if an air gap is not installed. View a short video about a high drain loop:
