Bosch dishwashers are renowned for their reliability and efficiency. However, like all appliances, they are not immune to errors. When something goes wrong, these dishwashers display error codes to help users identify and resolve issues. This article provides an in-depth look at common Bosch dishwasher error codes, their causes, and how to fix them.

Common Bosch Dishwasher Error Codes

Error codes are a vital diagnostic tool. They allow users to pinpoint the exact problem. Below is a list of some of the most common Bosch dishwasher error codes and what they signify.

E15: Water in Base

The E15 error code indicates that water has leaked into the base of the dishwasher. Bosch dishwashers have a safety feature that activates a float switch if water accumulates in the base. This switch stops the appliance from operating to prevent further damage.

How to Fix

1. Disconnect the dishwasher from the power supply.

2. Remove the lower kickplate to access the base.

3. Use a sponge or cloth to soak up the water.

4. Check for any visible leaks and repair them.

5. Reconnect the dishwasher and run a test cycle.

E24: Drainage Issue

The E24 error code indicates that the dishwasher is not draining properly. This issue is often caused by a blockage in the drain hose or pump, preventing water from being expelled from the appliance.

How to Fix

1. Check the drain hose for any kinks or blockages.

2. Clean the filter and drain pump of any debris.

3. Ensure the sink drain is not clogged, as it can cause backflow.

4. If the problem persists, consider replacing the drain pump.

E09: Heating Element Failure

The E09 error code is related to a failure in the heating element. This error means that the water is not being heated to the required temperature, affecting the dishwasher’s cleaning performance.

How to Fix

1. Turn off the dishwasher and disconnect it from the power supply.

2. Access the heating element, usually located at the bottom of the appliance.

3. Test the element for continuity using a multimeter.

4. If it shows no continuity, replace the heating element.

E19: Water Inlet Valve Issue

The E19 error code indicates a problem with the water inlet valve. This valve controls the flow of water into the dishwasher. A malfunctioning valve can lead to insufficient water entering the appliance, affecting its operation.

How to Fix

1. Turn off the water supply to the dishwasher.

2. Access the water inlet valve, typically located at the bottom of the appliance.

3. Inspect the valve for any visible damage or debris.

4. Clean the valve or replace it if necessary.

5. Restore the water supply and test the dishwasher.

E22: Filter Blockage

The E22 error code signals that the dishwasher’s filter is clogged. A blocked filter can prevent proper water flow, leading to subpar cleaning results and potential strain on the dishwasher’s components.

How to Fix

1. Remove the lower dish rack to access the filter.

2. Take out the filter and clean it under running water.

3. Use a soft brush to remove any stubborn debris.

4. Reinsert the filter and run a rinse cycle to check for any improvements.

Preventing Future Errors

Regular maintenance can prevent many common Bosch dishwasher errors. Here are some tips to keep your dishwasher running smoothly:

1. Regularly Clean the Filter

Cleaning the filter at least once a month can prevent blockages and ensure proper water flow.

2. Inspect the Drain Hose

Periodically check the drain hose for kinks or blockages to avoid drainage issues.

3. Use the Correct Detergent

Ensure you are using a detergent that is compatible with your Bosch dishwasher to prevent soap buildup and residue.

4. Run Hot Water Before Starting a Cycle

Running hot water from your sink before starting the dishwasher can help achieve better cleaning results by ensuring the water entering the dishwasher is hot from the start.

5. Regularly Check for Leaks

Inspect the dishwasher’s base and connections for any signs of leaks, as these can lead to more serious issues over time.

Conclusion: Keeping Your Bosch Dishwasher in Top Condition

Understanding Bosch dishwasher error codes and their fixes can save you time and money. By identifying the issue, you can take the necessary steps to resolve it and keep your dishwasher running efficiently. Regular maintenance and attention to detail are key to preventing these errors from occurring in the first place.
