Geschirrspüler Bosch Super Silence Fehler E24

Willkommen in Deutschland! Whether you're here for a short getaway, settling in as an expat, or simply exploring the local culture, dealing with household appliances is often part of the experience. And let's be honest, a broken dishwasher can really put a damper on your trip! If you're staring at your Bosch Super Silence Geschirrspüler (dishwasher) and seeing the dreaded Fehler E24, don't panic! This guide is here to help you troubleshoot the issue like a pro, so you can get back to enjoying your time in Germany.

What Does Fehler E24 Mean?

Fehler E24, or Error E24, on a Bosch Super Silence dishwasher indicates a problem with draining water. Basically, the dishwasher isn't able to empty the water after a wash cycle. This could be due to a variety of reasons, ranging from simple clogs to more complex mechanical issues. The good news is that many of these issues can be resolved quickly and easily, without needing to call a technician.

Before You Start: Safety First!

Before you begin troubleshooting, always prioritize your safety:

Disconnect the dishwasher from the power supply. Find the circuit breaker in your fuse box (Sicherungskasten) and switch off the breaker that controls the dishwasher. This prevents any accidental shocks during your repair attempt.
Turn off the water supply to the dishwasher. This is usually located under the kitchen sink.
Wear gloves. You'll be dealing with dirty water and potentially sharp objects.
Have a towel handy. Spillage is inevitable!

Troubleshooting Steps for Fehler E24

Now that we've covered safety, let's get down to business. Follow these steps in order, starting with the simplest solutions first:

1. Check the Drain Hose

The drain hose is the flexible tube that carries wastewater from the dishwasher to the drain under your sink or to a dedicated drain connection. Here's what to look for:

Kinks or Bends: Make sure the hose isn't kinked or bent, as this can restrict water flow. Straighten out any kinks you find.
Blockages: Disconnect the hose from the drain connection (usually secured with a clamp). Hold it up and check for any visible debris or blockages. If you see something, try flushing it out with water from a garden hose or using a long, flexible brush.
Correct Installation: Ensure the drain hose is installed correctly. It shouldn't be inserted too far into the drain pipe under the sink, as this can create a siphon effect, preventing proper drainage. Ideally, it should have a high loop before connecting to the drain.

Tip: When reconnecting the drain hose, make sure the clamp is tight to prevent leaks.

2. Inspect the Sink Drain

Sometimes the problem isn't with the dishwasher itself, but with the sink drain that it's connected to. Here's how to check it:

Check for Clogs: Run water in the sink and see if it drains properly. If it drains slowly or not at all, you likely have a clog in the sink drain.
Clean the P-Trap: The P-trap is the curved pipe under the sink that traps debris and prevents sewer gases from entering your home. This is a common spot for clogs to form. Place a bucket under the P-trap, loosen the slip nuts, and carefully remove the trap. Clean out any debris you find inside.

Tip: A simple plunger can often clear minor sink clogs. For tougher clogs, consider using a drain snake or chemical drain cleaner (use with caution and follow the instructions carefully!).

3. Clean the Dishwasher Filter

The dishwasher filter catches food particles and debris to prevent them from clogging the drain pump. A dirty filter can restrict water flow and cause the E24 error.

Locate the Filter: The filter is usually located at the bottom of the dishwasher, near the spray arms. It typically consists of a coarse filter and a fine filter.
Remove and Clean the Filter: Twist and remove the filter assembly. Separate the coarse and fine filters and rinse them thoroughly under running water. Use a brush to remove any stubborn debris.
Reassemble and Replace: Reassemble the filter assembly and twist it back into place, ensuring it's securely locked.

Tip: Clean the dishwasher filter regularly (at least once a month) to prevent build-up and ensure optimal performance.

4. Check the Drain Pump

The drain pump is responsible for pumping the wastewater out of the dishwasher. If the pump is clogged or malfunctioning, it can cause the E24 error.

Access the Drain Pump: This is the most involved step, and depending on your model, accessing the drain pump may require removing the lower spray arm, filter housing, and possibly a plastic cover. Refer to your dishwasher's user manual for specific instructions.
Inspect for Obstructions: Once you have access to the drain pump, look for any obstructions, such as food particles, glass shards, or small objects. Use tweezers or pliers to carefully remove any debris you find.
Test the Pump (Advanced): If you're comfortable working with electricity and have a multimeter, you can test the pump's continuity. Disconnect the wires from the pump and use the multimeter to check for a reading. If there's no continuity, the pump may be faulty and need to be replaced.

Warning: Working with the drain pump can be challenging, especially if you're not familiar with appliance repair. If you're unsure about any step, it's best to consult a qualified technician.

5. Check the Non-Return Valve (Rückschlagventil)

The non-return valve, or check valve, prevents wastewater from flowing back into the dishwasher after it's been pumped out. If this valve is stuck or damaged, it can interfere with drainage.

Locate the Non-Return Valve: The non-return valve is usually located near the drain pump. It may be integrated into the pump housing or a separate component.
Inspect and Clean: Check the valve for any debris or obstructions. Clean it thoroughly with water and a brush. Make sure the valve moves freely in one direction and prevents flow in the opposite direction.
Replace if Necessary: If the valve is damaged or doesn't function properly, it should be replaced.

Resetting the Dishwasher

After you've addressed the potential causes of the E24 error, it's a good idea to reset the dishwasher. This can sometimes clear the error code and allow the dishwasher to function normally.

Power Cycle: Turn off the dishwasher using the power button. Then, disconnect it from the power supply by switching off the circuit breaker for a few minutes. Turn the breaker back on and power on the dishwasher.
Factory Reset (if available): Some Bosch dishwashers have a factory reset function. Refer to your user manual for instructions on how to perform a factory reset. This will reset the dishwasher to its original settings.

Still No Luck? Calling a Technician

If you've tried all of the troubleshooting steps and the E24 error persists, it's time to call a qualified appliance repair technician. There may be a more complex issue, such as a faulty drain pump motor, a problem with the control board, or a wiring issue.

Where to Find a Technician in Germany:

Bosch Customer Service: Contact Bosch customer service directly. They can often recommend authorized repair technicians in your area.
Online Directories: Use online directories such as Gelbe Seiten (Yellow Pages) or MyHammer to find appliance repair technicians near you.
Ask Locals: Ask your landlord, neighbors, or friends for recommendations.

Remember to describe the problem (Fehler E24) clearly and provide the model number of your dishwasher when contacting a technician.

Prevention is Key

To prevent the E24 error and other dishwasher problems in the future, consider these tips:

Scrape Plates: Always scrape off large food particles from plates and dishes before loading them into the dishwasher.
Clean the Filter Regularly: Clean the dishwasher filter at least once a month.
Run a Cleaning Cycle: Use a dishwasher cleaner regularly (according to the manufacturer's instructions) to remove grease and build-up.
Check the Drain Hose: Periodically inspect the drain hose for kinks, bends, or damage.
Use Quality Detergent: Use a good quality dishwasher detergent and follow the manufacturer's recommendations.

By following these tips, you can keep your Bosch Super Silence dishwasher running smoothly and avoid the frustration of dealing with the dreaded Fehler E24. Enjoy your stay in Germany!
