Having a Bosch dishwasher not draining can be a frustrating experience. Not only is it inconvenient and time-consuming to clean up the water, but it also poses a health hazard if left unchecked. Fortunately, with the right know-how and tools, you can easily fix this issue on your own. In this article we will discuss how to troubleshoot and resolve common causes of Bosch dishwasher not draining issues so that you can get back to enjoying spotless dishes in no time!
How To Drain A Bosch Dishwasher
The first step to troubleshooting a Bosch dishwasher not draining is to identify the cause. This can be done by inspecting the drain hose, water inlet valve, and pump motor for any signs of damage or blockages. If any of these components are blocked or damaged, you will need to replace them before attempting to fix the not draining issue.
Once you have identified and replaced any damaged or blocked components, the next step is to inspect the drain hose for kinks or debris. If there are any kinks in the hose, use a pair of pliers to straighten them out and make sure there isn’t any debris built up in the hose. If you have checked all of these components and still have not been able to resolve the issue, it is time to check the pump motor.
The pump motor is responsible for pushing water through the drain hose. If this component is blocked or damaged, it can prevent your dishwasher from draining correctly. To test the pump motor, unplug the dishwasher and remove the drain hose from the motor. If there is any debris or buildup in the pump motor, clean it out using a damp cloth to ensure proper drainage. Once this is done, reattach the drain hose and plug your dishwasher back in to test if it drains correctly. [1]
Obstructed Dishwasher Drain Hose
For a Bosch dishwasher to perform its best, it’s important that the drain hose is unblocked and working properly. When obstructions block water from exiting the hose, it can cause your dishwasher to not function as expected – luckily this issue is easily fixable by restoring proper flow in the drain.
Follow These Guidelines To Remove A Bosch Dishwasher Drain Hose Obstruction
The most common cause of a Bosch dishwasher not draining is an obstruction in the drain hose. To remove this, you’ll need to follow these steps:
- Unplug your Bosch dishwasher from the power source. To ensure complete safety, be sure to either switch off the circuit breaker or disconnect it from its wall outlet.
- Locate the drain hose. It is typically located near the back of the dishwasher, near the pump and motor assembly.
- Remove any clogs in the drain hose using a pair of needle-nose pliers or tweezers. You may also want to use an old toothbrush to remove any stubborn debris. Ensure that all food remnants and other obstructions are eliminated from the drain hose to prevent clogging.
- After all obstructions have been removed, replace the drain hose and reconnect it to the pump and motor assembly.
- Plug your Bosch dishwasher back into the power source, then turn on the circuit breaker or plug it into the wall outlet. Test the dishwasher to make sure it drains properly.
Bosch Dishwasher Filter Requires Cleaning
In order to return your Bosch dishwasher to optimal performance, make sure you clean the filter if it is not draining as expected.
The filter is located in the bottom of the dishwasher and is responsible for catching food particles that could clog up the drain line. To refresh the filter, start by unscrewing it with a flat-head screwdriver to remove it from your dishwasher. Once it is removed, rinse it off in a sink or bucket of warm water and use a soft brush to scrub away any debris that has built up over time. After cleaning the filter, re-install it into the dishwasher and run a cycle to see if the problem has been resolved. If not, there may be an issue with your drain line that requires additional attention. If you’re still struggling with the issue, it’s time to contact an appliance repair technician for additional help. [2]
Here’s How To Clean A Bosch Dishwasher Filter
If the Bosch dishwasher is not draining correctly, you can try cleaning the filter. The filter captures any remnants of food or debris that may have been left on your dishes and stops them from obstructing your drainage. Here’s what you need to do:
- Unplug your machine and remove the bottom kick plate.
- Locate the filter in the bottom of the dishwasher and remove it.
- Clean out any food particles or debris that may have gotten stuck inside the filter.
- Rinse off the filter with warm water, then reinstall it back into your machine.
- Put the kick plate back in place and plug the machine back in.
- Run a cycle to check if your Bosch dishwasher is now draining correctly. If not, you may need to contact an appliance repair specialist for further diagnosis and repairs. [3]
Bosch Dishwasher Drain Pump Failure
If your Bosch dishwasher is struggling to drain, there are various root causes that should be explored. A frequent issue experienced is the malfunctioning of drain pumps. If this occurs, you may hear a humming sound when the dishwasher is operating but no water will flow out. To fix this, remove the lower access panel to access the pump. If it has failed, you should replace it. [4]
Check Air Gap And Garbage Disposal
To ensure a Bosch dishwasher is working optimally and draining quickly, a few simple steps can be taken. Firstly, check the air gap at the top of your sink – if this area becomes blocked it won’t allow dirty water to flow away correctly. Unclogging any debris here will help keep your machine in great condition. To unclog it, unscrew the cap, remove the rubber gasket, clean out the filter, and reinsert the cap. The garbage disposal also needs to be checked for clogs. Remove any large pieces of food that may have accumulated in it and run a few cups of cold water through it to ensure everything is cleared away. If these steps do not work, a professional plumber may be needed.
How To Prevent Bosch Dishwasher Clogs
There are a few steps you can take to help prevent clogs in your Bosch dishwasher.
- Make sure all dishes, including utensils, pots and pans, etc., are free of food residue before washing.
- Clean the filter after each use by running it through the cycle with only liquid detergent.
- Use a dishwasher cleaner, such as Affresh®, to help keep your filter and dishwasher clean and free of build-up.
- Check the drain hose for any clogs or kinks that could impede water flow before running a cycle.
- Place larger dishes on the lower rack instead of the top, to help prevent blocking the spray arm.
- Make sure all dishes are securely loaded on the rack and not touching each other or the walls of the dishwasher.
- Don’t overload your dishwasher; too much in one cycle can lead to clogging issues.
- Rinse off food particles from dishes before placing them in the dishwasher.
- Use a rinse aid, such as Jet Dry, to help reduce spotting and improve drying performance.
- Regularly clean the gasket around the door of your Bosch dishwasher as food particles can accumulate here and cause clogs. [5]
Tips To Fixing Bosch Dishwasher Not Draining
- Clean out any clogs from the filters. Bosch dishwashers have two filters located at the bottom of them, one for food particles and one for detergent. Cleaning out these filters regularly will help prevent a drainage issue.
- Ensure your garbage disposal is functioning optimally. If the garbage disposal isn’t functioning, it can block water from draining away from the dishwasher.
- Check for any kinks in the drain line that could be preventing water from draining. These can be difficult to spot, so you might need a flashlight or mirror to help you find them.
- Check the drain pump for any damage or blockage. If the pump has been damaged, it will need to be replaced.
Make sure there aren’t any foreign objects blocking the drain hose. If there are, remove them and check for any other blockages. - Lower the drain hose so that it is below the water line in your sink or garbage disposal. This will help ensure that gravity can do its job of draining the water away from the dishwasher.
- Make sure the door latch on your Bosch dishwasher is completely closed. If not correctly positioned, the dishwasher’s draining capabilities will be compromised.
