Bosch Dishwasher Drain Pump Keeps Running

Bosch Dishwasher not Draining Water – Fixed

When you hear your dishwasher draining after a cycle, you know that the right functions are taking place so that you can have clean and dry dishes once the cycle has completed. However, if the cycle has finished and you are still hearing the drain pump continually run, a bit of concern begins to creep in. If you have a Bosh dishwasher and the drain pump keeps running even when the cycle is over, take a look below to see what you need to do.

If your Bosch dishwasher keeps running, this is caused by your dishwasher receiving a signal that there is a leak. You will need to check to see if there are any apparent leaks within the appliance and if you see one, it will need to be fixed as soon as possible to avoid further issues.

If you dont see any leaks within the dishwasher, then you may be wondering what could cause your appliance to be getting such a message. If there are any hoses or tubes that are clogged or full of debris, this can cause the float switch within the dishwasher to think that there is still water present, which will force the drain tube to keep on draining. If this is the case, any clogged hoses or tubes will need to be removed and cleared of any obstructing debris.

What Do You Do When Your Bosch Dishwasher Doesnt Drain

Dishwashers have two drains, one for dirty dishes and one for clean dishes. To clear the dirty dishes from the drain, turn off the power switch and remove the plug from the outlet. Then, open the door and pull out the rack. Next, lift the basket out of the washer and place it upside down on the floor. Finally, remove the bottom panel of the washer and pour hot water into the sink until the water level reaches the top of the drain hole. This will flush out any remaining food particles. After that, replace the panel and reattach the plug. For cleaning the clean dishes, follow these steps: Turn off the power switch and unplug the appliance. Remove the plug from the outlet and remove the rack. Open the door and remove the basket. Pour hot water into the sink and wait for the water to fill the drain hole. Once the water reaches the top of the hole, stop pouring water and let the water run out. Replace the panel and reattach plug.

How Do You Force A Bosch Dishwasher To Drain

If you notice standing water in your dishwasher, it could mean that something is clogged in the drain line. To clear the blockage, turn off the power to your dishwasher and remove the door panel. Then, pour warm water into the bottom of the washer until the level reaches the drain pump. Wait about 10 minutes and then try running the wash cycle again. If the problem persists, call a professional plumber.

Bosch Dishwasher Not Draining But No Blockage

At this point, you know that the most common problem for Bosch dishwashers, when it comes to draining problems, is a block somewhere within the appliance. This can be easily resolved for most by simply removing and cleaning the filter at the bottom of the appliance or clearing out other spots that have the potential to block. However, if you clear these places of all debris and your dishwasher still isnt draining, what might be causing the problem?

If your Bosch dishwasher isnt draining, but there is no blockage, a failed drain pump may be the problem. The drain pump is a small part that is not incredibly expensive, but proper installation is essential when it comes to avoiding any further draining issues or potential leaks.

    Drain Line Is Clogged

    Oh, NO! There is still water in my Bosch dishwasher! Unnerving as this is, check the drain line that connects from the dishwasher to the sink or garbage disposal. This is a very common place for clogs to form. Remove the drain hose and clear it out. Clean out the fittings near the garbage disposal while the hose is disconnected to ensure there is no blockage.

    Bosch Dishwasher Not Draining

    A Bosch dishwasher is an appliance that gives owners the freedom to get their dishes clean without ever having to question whether or not their dishes are going to come out clean, dry, and ready to be used without any additional care. However, part of this cleaning process includes the ability of the dishwasher to drain dirty water out of the appliance so drying can ensue. If you have a Bosh dishwasher and it isnt draining, read below to find the solution.

    If your Bosch dishwasher is not draining, it could be that the air gap on your sink is clogged. To resolve this problem, remove the small piece that is either screwed off or easily popped off on the back of your sink and remove any debris from the area before trying to drain your dishwasher again.

    Water is drained from your dishwasher and through the air gap, but sometimes, when water reaches the very top of the air gap, small bits of debris get stuck, which causes the water to begin to drain at a slower rate. If you see debris there, this is likely the issue. Once you have the area cleaned, be sure to load dishes that are free of any large pieces of food or any other items that could easily get stuck during the draining process to help prevent reoccurrence.

    Check Air Gap And Garbage Disposal

    The final step in Bosch dishwasher troubleshooting involves checking an air gap or garbage disposal for clogs. If you have one of these components, they share a common drain with the dishwasher. Consequently, if either become clogged with debris, food particles can block the shared drain and prevent dishwasher water from exiting.

    Always run a garbage disposal before starting your dishwasher to clear it of any food scraps that can clog the drain. If you have an air gap, clean it regularly by removing the cover and wiping away any visible debris with a paper towel.

    If you still find your Bosch dishwasher not draining water or your dishwasher leaves dishes wet, Appliance Service Station can help. Schedule a fast and reliable repair with one of our expert technicians!

    Checking On The Filter

    A filter is usually fitted at the bottom of the Bosch dishwasher to prevent food particles or debris from passing through the drain hose. This is a preventative measure to ensure you do not experience drainage problems with your dishwasher. However, some particles may still pass and clog the drain hose. Hence, it is vital to check whether this part is clean. If it is blocked, then remove the debris and clean it thoroughly to improve the drainage of the dishwasher.

    Cleaning the filter is the easy bit. You can get some tutorials online for this and learn the necessary skills in filter cleaning.

    Some units skip the air gap and drain directly into the garbage disposal by using what is called a high drain loop, which is an extra-long drain pipe that’s fastened to the underside of the countertop. If you have a high drain loop, skip to step #3.

    Pull the cover off your air gap and check for debris and tiny bits of food.

    Check For Clogs In The Drain Hose

    To detach a drain hose from the air gap , you’ll need:


  • Using a screwdriver and the pliers, disconnect the drain hose that is attached to the air gap , drain the water, and check if the hose is blocked. You’ll only be able to see the section of the drain that’s exposed under the sink.
  • To see if the drain hose is blocked, run the dishwasher on the rinse cycle and hold the hose over the bucket. If the dishwasher doesn’t drain, then the drain hose is blocked. You might try to use a plumbing snake or a hanger to push out the clog.
  • If you can’t find the clog in the section of drain under the sink, it’s likely in the portion you can’t see, directly behind the dishwasher. Most drain hoses run through a hole in the cabinet and the dishwasher may need to be pulled fully out for closer inspection. Before you pull it out, you’ll need to unscrew the two L brackets that connect the top of the dishwasher to the underside of the counter. You may also need to adjust the height of the dishwasher by screwing its feet down lower to give you clearance at the top. If this is too difficult, it might be time to call a plumber.

    Bosch Dishwasher Not Draining At End Of Cycle

    Water remaining at the end of a cycle can be caused by a few different things. Fortunately, most of these causes are easy to fix yourself.

    One possible reason for water remaining in your Bosch dishwasher is that the drain hose is clogged. The drain hose is the flexible pipe that runs from the dishwasher to the drain under your sink.

    To check if the drain hose is clogged, first disconnect it from the dishwasher. Then, put a bowl under the end of the hose and see if water drains out. If it doesnt, then you probably have a clog in your drain hose.

    To fix a clogged drain hose, start by disconnecting the hose from the dishwasher. Then, use a plunger to try and dislodge the clog. If that doesnt work, you can try using a wire hanger to fish the clog out. If neither of these methods work, you may need to replace the drain hose.

    Another possible reason for water remaining in your Bosch dishwasher is that the dishwasher isnt level. If the dishwasher isnt level, then water can pool in the tub at the end of a cycle.

    To check if your dishwasher is level, open the door and look at the tub. The tub should be level with the door opening. If its not, then youll need to adjust the leveling legs.

    Bosch Dishwasher Not Draining Properly – How to Fix

    It is one thing if your dishwasher is not draining completely and you notice there is standing water at the bottom of your appliance once the dishwashing cycle has finished, but it is a whole other issue when a dishwasher is not draining, but is also leaking.

    If your Bosch dishwasher is not draining and is also leaking, the issue could lie in a faulty float switch. Check to make sure that the float switch is not stuck on any other piece of the dishwasher and inspect it for any kind of damage, as this can cause the appliance to overfill and thus, leak.

    After you remove the bottom rack of the dishwasher, you should be able to easily find the float switch at the base of your Bosch dishwasher. If you notice that there is damage to the switch, this is likely the problem, as a damaged float switch will allow more water to fill up within the dishwasher than is needed, which can result in appliance leaking.
