A dishwasher drains into the sink.

A blocked drainage hose is the primary cause behind dish washers draining into the sink. Fixing this problem is fairly simple, but it must be done properly or it can create more problems than it solves.

If a dishwasher does not drain, it is usually due to a blocked drain pipe,bloked air gap or a clogged sink trap.

There are a few reasons why your dishwasher may not be draining. We will start with the main reasons.

The first reason is that the kitchen sink is clogged and many people don’t realize that their dishwasher drains into a port on the garbage disposal and if the drain is clogged this will affect the dishwasher. Also people don’t realize if the garbage disposal is broken and not working this too can affect the way the dishwasher drains. The next reason is that the pump on the dishwasher is broken and if this is the case you should not call a plumber but instead call an appliance repair company.

Another reason your dishwasher may not be draining right is if the appliance was installed wrong, a dishwashers discharge hose should come from the unit and go up as high as it can and then back down to the connection on the sink. This creates a trap and does not allow water to travel back to the dishwasher when using the kitchen sink. Some building codes may also require an air gap fitting.

Another very common reason a dishwasher does not drain is if a plumber installs a garbage disposal and forgets to knock out the plug on the port hole for the dishwasher drain. Those are the main reasons why your dishwasher does not drain. It is important for the customer to know the reasons why their dish washer would not drain so they know whether to call an appliance repair company or plumbing company.
