Bosch dishwashers are known for their efficiency and quality. However, like all appliances, they may encounter issues that require troubleshooting. Understanding the error codes and knowing how to address them can help resolve problems quickly.

Common Bosch Dishwasher Error Codes

E15 Error Code (Water Leak Detected)

• Cause: A water leak has been detected in the dishwasher.
• Solution: Check for leaks around the door, hoses, or bottom of the unit. Inspect the float switch for any debris that could cause it to malfunction. If necessary, clean or replace the float switch.

E24 Error Code (Drainage Issue)

• Cause: The dishwasher is unable to drain water properly.
• Solution: Clean the filter and check for blockages in the drain hose. If there is no obstruction, the drain pump may need to be inspected or replaced.

E09 Error Code (Heating Element Issue)

• Cause: The heating element is malfunctioning.
• Solution: Inspect the heating element for damage and test it with a multimeter. If it’s faulty, replace the heating element to restore normal function.

Troubleshooting Tips

• Use the Correct Detergent: Always use dishwasher detergent that is compatible with your Bosch model to avoid excess foam, which can cause drainage problems.
• Check the Water Temperature: If the dishwasher isn’t getting hot enough, it may not clean dishes properly. Verify that the water heater is working correctly.
• Load Properly: Load your dishwasher properly to avoid blocking the spray arms and ensuring adequate water flow.

Maintenance Advice

• Run Cleaning Cycles: Run a cleaning cycle with dishwasher cleaner or vinegar to prevent mineral buildup.
• Inspect Filters Regularly: Clean the filters to prevent food particles from clogging the drain pump.
• Check Seals: Wipe the door seals clean to prevent leaks and mold growth.
