Dishwashers have become indispensable in modern households, providing convenience and efficiency in our daily routines. Bosch, a renowned brand, is known for its high-quality dishwashers. However, encountering an E24 error code on your Bosch dishwasher can be frustrating. This common issue, often related to drainage problems, can disrupt your kitchen’s workflow. In this comprehensive guide, we’ll explore the reasons behind the E24 error code in Bosch dishwashers and provide step-by-step instructions on how to fix it. Our aim is to help you get your dishwasher back to its optimal performance with minimal hassle.

Common Causes of the E24 Error Code

Several factors can lead to the E24 error code:

1. Blocked Filters: Over time, food particles and debris can clog the filters, hindering water flow.
2. Obstructed Drain Hose: A kinked or blocked drain hose can prevent water from draining out.
3. Faulty Pump: A malfunctioning pump can fail to expel water effectively.
4. Clogged Air Gap: If your dishwasher uses an air gap, blockages can impede drainage.

How to fix the E24 error code?

Fix 1: Inspecting and Cleaning the Filters in Your Bosch Dishwasher

The first and often most effective step in addressing the E24 error code on a Bosch dishwasher involves inspecting and cleaning the filters. Over time, filters can accumulate food particles, grease, and other debris, leading to blockages that prevent your dishwasher from draining properly.

• Locate the Filters: Begin by finding the filters in your dishwasher. Typically, they are located at the bottom of the machine, near the spray arms. Bosch dishwashers usually have a cylindrical and a flat filter.
• Remove the Filters: Carefully take out the filters. The cylindrical filter usually twists out, while the flat filter should lift straight up. Be gentle to avoid damaging them.
• Rinse the Filters: Hold the filters under running water. It’s best to use warm water for this. As you rinse, gently rub the mesh and plastic parts with your fingers or a soft brush to dislodge and remove any trapped debris.
• Check for Damage: After cleaning, inspect the filters for any signs of damage. If you find tears in the mesh or cracks in the plastic, replace the filters to ensure proper functioning.
• Clean the Filter Housing: Before reinserting the filters, wipe down the area where they sit. This space can also harbor debris, so a quick clean can prevent future blockages.
• Reinsert the Filters: Once everything is clean and dry, put the filters back in place. Make sure the cylindrical filter is locked in correctly, and the flat filter sits snugly on top. It’s crucial that these are reinserted properly to avoid any issues during the dishwasher’s operation.
• Run a Test Cycle: After the filters are back in place, run a short wash cycle without any dishes. This helps to clear out any residual debris and checks if the E24 error has been resolved.

By regularly cleaning and maintaining the filters in your Bosch dishwasher, you can prevent the E24 error code from recurring. This simple yet effective fix not only resolves immediate issues but also prolongs the life of your appliance.

Fix 2: Checking and Adjusting the Drain Hose

A common cause of the E24 error code in Bosch dishwashers is a problem with the drain hose. If the hose is kinked, blocked, or improperly positioned, it can prevent water from draining out of the dishwasher effectively.

• Access the Drain Hose: First, locate the drain hose. It is usually connected to the drain pump underneath the dishwasher and runs to the kitchen sink or garbage disposal. You may need to remove the kick plate or lower front panel of the dishwasher for better access.
• Inspect for Kinks or Bends: Carefully examine the hose for any kinks, twists, or sharp bends. These can restrict water flow. Gently straighten out any kinks you find. If the hose is damaged or has a permanent kink, consider replacing it.
• Check for Blockages: Feel along the length of the hose for any bulges or areas that seem clogged. If you suspect a blockage, disconnect the hose. This usually involves loosening a clamp. Once removed, flush the hose with water to clear any debris.
• Ensure Proper Hose Elevation: The drain hose should loop up to the bottom of the countertop before connecting to the drainage system. This prevents sink water from flowing back into the dishwasher. If the hose is hanging down or not elevated, reposition it to the correct height and secure it in place.
• Reconnect and Test the Hose: After making adjustments, reconnect the hose securely. Run a test cycle on your dishwasher to check if the issue is resolved.

Fix 3: Evaluating and Rectifying Issues with the Pump

The dishwasher’s pump plays a crucial role in draining water. A malfunctioning pump can be the root cause of the E24 error code.

• Locate the Pump: You can find the pump underneath the filters you previously cleaned. It’s typically at the bottom of the dishwasher.
• Check for Obstructions: Look into the pump opening for any visible debris. Sometimes, food particles, glass shards, or other objects can block the pump impeller. If you find any obstructions, carefully remove them. Ensure the impeller can move freely.
• Inspect for Damage: Check the pump and its surrounding area for signs of damage, like cracks or wear. If the pump is visibly damaged, it may need to be replaced.
• Listen for Unusual Noises: When running a cycle, listen for any unusual noises coming from the pump area. Grinding or humming sounds can indicate a pump issue.
• Seek Professional Help: If after cleaning and checking there are still issues, or if the pump needs replacement, it might be best to consult a professional. Dishwasher pumps are intricate, and improper handling can lead to more significant issues.

Regularly performing these maintenance steps can significantly reduce the likelihood of facing the E24 error code. Not only do they solve the immediate problem, but they also contribute to the longevity and efficiency of your Bosch dishwasher.

Fix 4: Clearing the Air Gap or Garbage Disposal

If your Bosch dishwasher connects to an air gap or a garbage disposal, a blockage in these areas can lead to the E24 error code. The air gap prevents dirty water from flowing back into the dishwasher, and if clogged, it can impede proper drainage.

• Inspect and Clean the Air Gap: The air gap is usually a small, cylindrical fixture on top of the sink. To clean it, remove the cap and check for debris. Clear out any buildup you find. This can be done using a small brush or by rinsing it under water.
• Check the Garbage Disposal Connection: If your dishwasher drains through the garbage disposal, ensure it’s not clogged. Sometimes, new garbage disposals have a knockout plug that needs to be removed before connecting a dishwasher. If you’ve recently installed a disposal, check if this plug has been removed.
• Run the Garbage Disposal: Before running the dishwasher, turn on the garbage disposal. This can clear any debris that might prevent water from draining out of the dishwasher.

Fix 5: Resetting the Dishwasher

Sometimes, a simple reset can clear the E24 error code. This process can help the dishwasher’s system to recalibrate and potentially resolve any minor electronic glitches.

• Turn Off the Power: Before resetting, ensure safety by turning off the power to the dishwasher. This can be done either by unplugging it or turning off the circuit breaker.
• Wait for Reset: Leave the dishwasher without power for about one minute. This short period allows the dishwasher’s electrical components to reset.
• Restore Power and Run a Test Cycle: After waiting, restore power to the dishwasher. Turn it on and run a test cycle to see if the error code has been cleared.

These additional fixes provide further avenues to resolve the E24 error code in your Bosch dishwasher. Regularly performing these checks and maintenance steps can prevent future occurrences and keep your dishwasher running smoothly. If the error persists after trying these fixes, it might be time to consult a professional technician for a more in-depth inspection and repair.

Fix 6: Cleaning the Sump

The sump, located at the bottom of your dishwasher, can accumulate debris and cause the E24 error. Cleaning the sump can resolve issues related to water drainage.

• Access the Sump: To reach the sump, you’ll need to remove the bottom rack of your dishwasher. The sump is usually located beneath the spray arms.
• Remove Debris: Check the sump for any visible debris like food particles, glass, or other objects. Carefully remove anything you find that shouldn’t be there. It’s important to be thorough yet gentle to avoid damaging any components.
• Clean and Rinse: After removing debris, clean the area with a sponge or a soft brush. Rinse it well to ensure all loose particles are washed away.

Fix 7: Checking the Water Inlet Valve

The water inlet valve controls the flow of water into your dishwasher. If it’s malfunctioning, it can cause drainage issues, contributing to the E24 error.

Locate the Inlet Valve: The water inlet valve is typically found behind the lower front panel or kickplate. You might need a screwdriver to remove this panel.

Inspect for Blockages and Damage: Look for any signs of damage or blockage in the valve. Limescale buildup or debris can hinder its function.

Test the Valve: Testing the valve can sometimes require technical skills and a multimeter. If you’re not comfortable with this, it may be best to call a professional.

Fix 8: Examining the Control Panel and Resetting Error Codes

A malfunction in the control panel can also lead to the E24 error. Resetting the control panel can sometimes clear this error.

• Inspect the Control Panel: Look for any signs of damage or malfunction on the control panel. Check if all buttons are responsive.
• Perform a Hard Reset: You can perform a hard reset by disconnecting the dishwasher from power for a longer period, like 10-15 minutes. This can help in resetting the control system and clearing error codes.
• Reset Error Codes: Some Bosch dishwashers allow you to reset error codes through a specific combination of button presses. Refer to your user manual for the exact procedure as it varies by model.
