Common Causes
Is your Bosch dishwasher not draining? Understanding the common causes can help you troubleshoot and fix the problem. Below are some frequent reasons why your Bosch dishwasher might not be draining.
Clogged Filter
A clogged filter can prevent your Bosch dishwasher from draining properly. Over time, food particles and debris can accumulate in the filter. This buildup can block the flow of water.
To check for a clogged filter:
- Turn off the dishwasher and unplug it.
- Locate the filter at the bottom of the dishwasher.
- Remove the filter by turning it counterclockwise.
- Rinse the filter under running water to remove debris.
Clean the filter regularly to avoid drainage issues.
Blocked Drain Hose
A blocked drain hose is another common cause. The drain hose can get kinked or clogged, preventing water from draining.
To check for a blocked drain hose:
- Disconnect the dishwasher from the power supply.
- Locate the drain hose at the back of the dishwasher.
- Inspect the hose for any kinks or bends.
- If the hose is clogged, use a long brush to clear the blockage.
Ensure the hose is straight and free of obstructions.

Initial Checks
If your Bosch dishwasher is not draining, initial checks can help identify the problem. Start with simple inspections before considering complex repairs. These steps can save time and money.
Power Supply
First, ensure the dishwasher has power. Check if it is plugged in properly. Look at the power outlet and test it with another appliance. If the outlet is faulty, the dishwasher won’t work.
Inspect the circuit breaker. Sometimes, a tripped breaker can cause power loss. Reset the breaker if necessary. Make sure the dishwasher’s door is fully closed and latched. An open door can interrupt the power supply.
Control Panel Settings
Next, review the control panel settings. Ensure the dishwasher is set to the right cycle. Sometimes, incorrect settings can prevent draining. Look for any error codes displayed on the control panel. These codes can provide clues about the issue.
Check the child lock feature. If activated, it can interfere with normal operations. Turn off the child lock by following the user manual instructions.
Sometimes, a simple reset can fix the problem. Turn off the dishwasher and unplug it for a few minutes. Plug it back in and restart the machine. This can reset the control panel and resolve minor glitches.
Inspecting The Filter
Your Bosch dishwasher not draining? The filter might be clogged. Inspecting the filter is the first step in solving this issue. A blocked filter can cause water to pool at the bottom. Follow these steps to check and clean the filter.
Locating The Filter
The filter is usually at the bottom of the dishwasher. Open the dishwasher door and pull out the bottom rack. Look for a cylindrical filter at the base.
The filter may have two parts: a coarse filter and a fine filter. Both need inspection. Refer to your user manual if unsure about the location.
Cleaning The Filter
First, twist the filter counterclockwise and lift it out. Rinse it under running water. Use a soft brush to remove debris.
For the fine filter, check for small food particles. Clean it gently with a brush. Ensure all holes are clear.
| Step | Action |
|---|---|
| 1 | Remove the bottom rack |
| 2 | Locate and remove the filter |
| 3 | Rinse under running water |
| 4 | Use a soft brush for cleaning |
| 5 | Reinstall the filter |
Make sure the filter is completely clean. Then, place it back in the dishwasher. Twist it clockwise to secure it.
A clean filter helps your dishwasher drain properly. Repeat this process monthly for best results.

Examining The Drain Hose
Is your Bosch dishwasher not draining? The drain hose might be the problem. Examining the drain hose is a crucial step in troubleshooting. Let’s break down the process to ensure your dishwasher drains properly.
Hose Position
First, check the position of the drain hose. Ensure the hose is not kinked or bent. A kinked hose can block water flow. The hose should have a gentle curve, not a sharp bend.
Make sure the hose is installed at the correct height. The hose should loop up to prevent backflow. This loop should be higher than the water level in the dishwasher.
Clearing Blockages
Next, inspect the hose for any blockages. Disconnect the hose from the dishwasher and the sink drain. Use a flashlight to look inside the hose. Any debris or food particles can block the hose.
To clear blockages, use a long brush or a piece of wire. Gently push the brush or wire through the hose. This will dislodge any debris. Rinse the hose with water to ensure it is clear.
Reattach the hose and run a test cycle on the dishwasher. Check if the water drains properly. If the problem persists, you may need to check other parts of the drainage system.
By examining the drain hose and ensuring it is in the right position and free of blockages, you can often resolve draining issues with your Bosch dishwasher. Stay tuned for more troubleshooting tips!
Checking The Air Gap
A Bosch dishwasher not draining can be frustrating. One potential culprit is the air gap. The air gap prevents dirty water from re-entering the dishwasher. Checking and cleaning it can often solve drainage issues.
Identifying The Air Gap
First, locate the air gap. It is usually a small cylinder on the back of the sink. It may have a chrome or plastic cover. Sometimes, it is hidden, so check thoroughly.
Refer to your Bosch dishwasher manual for exact details. Knowing its location helps in further steps.
Cleaning The Air Gap
Cleaning the air gap is simple. Start by removing the cover. You might need a screwdriver for this.
- Unscrew the top of the air gap.
- Remove any visible debris or food particles.
- Use a small brush or toothpick to clean inside the gap.
- Rinse the parts under warm water.
- Reassemble the air gap and screw the top back on.
Now, run a test cycle on your Bosch dishwasher. Check if the drainage issue is resolved.
Regularly cleaning the air gap can prevent future problems. Make it a part of your maintenance routine.

Testing The Drain Pump
Testing the drain pump is essential for resolving drainage issues in your Bosch dishwasher. This step helps identify if the pump is causing the problem or if another part is malfunctioning. Follow these steps to ensure your dishwasher drains properly and avoid further complications.
Pump Access
First, access the drain pump by removing the dishwasher’s lower front panel. This panel is usually located at the bottom of the dishwasher. Use a screwdriver to remove the screws holding the panel in place. Once removed, you will see the drain pump.
Ensure the dishwasher is unplugged to avoid any electrical hazards. Place a towel or container under the pump to catch any water that may spill out. Carefully disconnect the hoses attached to the pump. This will give you a clear view of the pump and its components.
Pump Functionality
Next, check the pump functionality by inspecting the pump for any visible damage. Look for cracks, broken parts, or debris that might be blocking the pump. Use a multimeter to test the pump’s electrical continuity. Set the multimeter to the ohms setting and touch the probes to the pump’s terminals.
The multimeter should show a reading between 50 to 200 ohms. If the reading is outside this range, the pump is likely faulty and needs replacement. Ensure the pump impeller spins freely. If it is stuck or hard to move, this could be causing the drainage issue.
If everything looks fine, reconnect the hoses and secure the panel back in place. Plug in the dishwasher and run a test cycle to see if the drainage problem is resolved.
Below is a table summarizing the key steps:
| Step | Action |
|---|---|
| 1 | Remove lower front panel |
| 2 | Disconnect hoses from the pump |
| 3 | Inspect pump for damage |
| 4 | Test pump with multimeter |
| 5 | Check impeller for movement |
| 6 | Reconnect hoses and secure panel |
| 7 | Run a test cycle |
By following these steps, you can effectively troubleshoot and resolve Bosch dishwasher drainage issues.
