When you have a dishwasher that isn’t draining, most homeowners will assume the dishwasher is broken, not realizing that the problem isn’t always the dishwasher. When a dishwasher isn’t draining after a cycle it might be due to a problem in the drainage system. The dishwasher has two steps to its drainage system. The first step is the water waste will run through the dishwasher filter. The next step is that the water is then sent through the drainage hose and through the home drainage system and finally, the sewer line. If there is a problem during any of these steps, the dishwasher will flood leaving a mess inside your home. The Original $49.95 Plumber will go over in more detail why a dishwasher isn’t draining.
Clogged Dishwasher Filter
Over time and after a number of dishwashing cycles it is common for the dishwasher’s filter to become clogged with food particles. Most dishwashers will have two filters. There is a large basket filter and a small mesh filter. These filters help catch any food particles that are left inside the machine, preventing them from entering the drainage system. When these filters become compacted or clogged they will prevent the water from draining out of the dishwasher. The dishwasher is fine. The filters simply need to be cleaned. It is recommended to prevent clogged filters in the future, you clean off all of the food particles off of the dishes before loading them in the dishwasher. When you need to check your dishwasher’s filters, look inside the appliance’s manual or go online. Each dishwasher filter location will vary. However, most dishwasher filters will be in the back of the appliance.
How Do I Know if My Dishwasher Drain Hose is Clogged?
A dishwasher’s drainage hose connects to the sink or garbage disposal. The hose will then connect to the drainage system. A clog can develop in the dishwasher’s connecting hose, or the sink/garbage disposal connecting hoses to the drainage system. When the dishwasher doesn’t drain and it is not the filters, your next step is to check the connecting hoses. You will want to check both hoses to see if they are clogged. The garbage disposal or sink is simple enough, just run water and see if it drains. If the sink and or garbage disposal drainage line doesn’t back up then the clog is in the dishwasher’s connecting hose. Clean out the hoses to restore the dishwasher’s drainage cycle.
Clog in Drainage System or Sewer
If the dishwasher is not draining and there isn’t a clog present in the hose or the filters the problem could be in the home’s drainage system or in the sewer line. If there is a clog in the drainage system all other sink and appliances connected to the same drainage piping line will also be effected. If the dishwasher and other appliances are also not draining correctly then there is a clog in the piping. If you have drainage problems in many parts of the home this often indicates a clog in the sewer line.
