Bosch Spülmaschine Super Silence Abpumpen Tastenkombination

Many owners of Bosch Super Silence dishwashers eventually encounter a situation where the machine fails to drain properly. This can manifest as standing water at the bottom of the dishwasher after a cycle or an error code related to drainage. Before calling a technician, it's worth trying to manually drain the dishwasher using a specific button combination. This article provides a comprehensive guide to manually draining your Bosch Super Silence dishwasher and troubleshooting potential problems.

Understanding Why Your Bosch Super Silence Isn't Draining

Several factors can cause a Bosch Super Silence dishwasher to stop draining. Identifying the cause can help prevent future occurrences. Common reasons include:

Clogged Filter: This is the most frequent culprit. Food particles, grease, and other debris accumulate in the filter, restricting water flow.
Blocked Drain Hose: The drain hose connects the dishwasher to the sink drain or garbage disposal. Kinks, twists, or blockages within the hose can prevent proper drainage.
Faulty Drain Pump: The drain pump is responsible for actively pumping the water out of the dishwasher. If the pump is malfunctioning or broken, it won't be able to remove the water.
Air Gap Issues: If your dishwasher is connected to an air gap (a small device on the sink that prevents backflow), it might be clogged.
Control Board Malfunction: In rare cases, a problem with the dishwasher's control board can interfere with the drain cycle. This is usually a more serious issue requiring professional repair.

Manually Draining a Bosch Super Silence Dishwasher: The Button Combination Method

Bosch dishwashers, including the Super Silence models, typically have a built-in function for manually draining water. This is activated using a specific sequence of button presses. The exact button combination can vary slightly depending on the specific model of your dishwasher. However, the following method is generally applicable:

General Button Combination Procedure

Power Off: Ensure the dishwasher is turned off.
Identify the Buttons: You'll usually need to identify the "Reset" or "Start/Pause" button, and another button – often one of the program selection buttons (e.g., "Intensive," "Eco," "Auto"). Consult your dishwasher's manual if you are unsure which buttons to use.
Simultaneous Press and Hold: Press and hold the "Reset" (or "Start/Pause") button simultaneously with the program selection button.
Power On and Continue Holding: While holding both buttons, turn the dishwasher on. Continue holding the buttons for approximately 3-5 seconds.
Listen for the Pump: You should hear the drain pump activate, indicating that the dishwasher is draining.
Release Buttons: Once you hear the pump running, release the buttons. The dishwasher should continue to drain until it is empty.
If it doesn't start: If you don't hear the pump after 5 seconds, repeat the process, ensuring you are pressing the correct buttons simultaneously and holding them firmly. Try different program buttons if the first one fails.

Important Note: If the dishwasher is completely full of water, it's best to manually remove some of the water with a container before attempting to drain it with the button combination. This will reduce the strain on the drain pump and prevent potential damage.

Specific Model Variations

While the general procedure is similar, some Bosch Super Silence models might require slightly different button combinations. Here are a few possible variations based on user reports and online forums:

Reset + Intensive: Press and hold the "Reset" button and the "Intensive" program button simultaneously while powering on the dishwasher.
Start/Pause + Eco: Press and hold the "Start/Pause" button and the "Eco" program button simultaneously while powering on the dishwasher.
Start/Pause + Power Button: Some older models may require pressing and holding the "Start/Pause" button and the power button simultaneously.

Always refer to your dishwasher's user manual for the most accurate instructions for your specific model. The manual will provide the correct button combination for manually draining the water.

Troubleshooting After Manually Draining

Even after successfully manually draining the dishwasher, the underlying problem that caused the drainage issue might still exist. Here are steps to take to diagnose and resolve the issue:

1. Clean the Filter

The filter is located at the bottom of the dishwasher, usually beneath the spray arm. To clean it:

Remove the lower spray arm.
Locate the filter assembly. It typically consists of a coarse filter and a fine filter.
Twist and remove the filter assembly.
Rinse both filters thoroughly under running water. Use a brush to remove stubborn debris.
Reassemble the filter assembly and reinstall it in the dishwasher. Make sure it's properly secured.
Reinstall the lower spray arm.

2. Inspect the Drain Hose

Check the drain hose for kinks, twists, or blockages. You can detach the hose from the sink drain or garbage disposal (turn off the water supply if necessary) and inspect it internally. A long, flexible brush or wire can be used to clear any blockages. Ensure the hose is properly reconnected and secured with clamps.

3. Check the Air Gap (If Applicable)

If your dishwasher is connected to an air gap, check it for clogs. Remove the air gap cover and clean out any debris that may be blocking the airflow. A small brush or pipe cleaner can be helpful.

4. Inspect the Drain Pump

Inspecting the drain pump requires some technical skill and may involve disassembling parts of the dishwasher. This is best left to a qualified technician if you are not comfortable performing such repairs. However, you can often access the drain pump area (usually at the bottom of the dishwasher) by removing the kick plate. Look for any visible obstructions or damage to the pump impeller. Never attempt to repair electrical components without disconnecting the power supply.

5. Run a Test Cycle

After cleaning the filter, inspecting the drain hose, and checking the air gap, run a test cycle to see if the dishwasher is draining properly. Monitor the dishwasher closely during the cycle to ensure the water is being pumped out effectively.

When to Call a Professional

If you've tried the manual drain procedure, cleaned the filter and drain hose, and the dishwasher still isn't draining, it's likely that there's a more serious problem, such as a faulty drain pump or a control board malfunction. In these cases, it's best to call a qualified appliance repair technician. Attempting to repair these components yourself can be dangerous and may void your warranty.

Do not continue to use the dishwasher if it is not draining properly, as this can lead to further damage.

Preventing Future Drainage Problems

To prevent future drainage problems with your Bosch Super Silence dishwasher, consider the following tips:

Scrape Food Off Plates: Before loading dishes into the dishwasher, scrape off large food particles to prevent them from clogging the filter and drain.
Regularly Clean the Filter: Clean the filter at least once a month, or more frequently if you notice excessive food debris.
Avoid Overloading: Overloading the dishwasher can prevent proper water circulation and drainage.
Use the Correct Detergent: Use only detergents specifically designed for dishwashers. Using too much detergent or the wrong type can cause excessive suds, which can interfere with drainage.
Run a Maintenance Cycle: Periodically run a dishwasher cleaner cycle to remove buildup and keep the dishwasher running smoothly. Bosch often recommends using a specific dishwasher cleaner.

By following these steps and regularly maintaining your Bosch Super Silence dishwasher, you can help prevent drainage problems and ensure its long-term performance.
