Common Bosch Dishwasher Error Codes and Symbols Explained
When your Bosch dishwasher displays an error code, it's a direct message about what's happening inside the machine. These alphanumeric sequences are vital for diagnosing issues, and knowing their common meanings can save you time and service calls. Understanding typical Bosch dishwasher warning symbols also helps differentiate between a minor alert and a more significant problem.
Drainage Issues: E24 and E25
The Bosch dishwasher E24 and Bosch dishwasher E25 errors are frequently associated with drainage problems. E24 typically indicates that the dishwasher is not draining water effectively. This can be caused by a kinked drain hose, a clogged drain pump filter (the Bosch dishwasher strainer), or a blockage in the household plumbing connection. E25 is often a more severe drainage fault, sometimes pointing to issues with the drain pump itself.
Troubleshooting Steps:
- Check the drain hose for kinks or obstructions.
- Clean the Bosch dishwasher strainer located at the bottom of the tub.
- Ensure the air gap or garbage disposal connection is not blocked.
- Verify that the drain hose is not inserted too far into the standpipe, which can create a siphon effect.
Water Inlet Problems: E15 and E22
A Bosch dishwasher E15 error is a critical alert signaling that the AquaStop system has detected water in the base tray, indicating a leak. The safety system will then shut off the water supply to prevent further flooding. The Bosch dishwasher E22 error code usually relates to issues with the water inlet, suggesting the dishwasher is not filling with enough water, or the water pressure is too low.
Troubleshooting Steps for E15:
- Turn off the dishwasher and unplug it.
- Carefully tilt the dishwasher forward to drain any water from the base tray.
- Inspect for obvious signs of leaks from hoses or seals.
- If the error persists after draining, professional service may be required.

For example, the Bosch 100 series dishwasher might have slightly different indicator placements than a premium Bosch 800 series dishwasher. However, the core troubleshooting for drainage (E24) or leak detection (E15) remains fundamentally the same. Always refer to your specific model's user manual for the most accurate interpretation of its warning symbols and error codes.
Troubleshooting Common Bosch Dishwasher Issues
Dealing with a malfunctioning Bosch dishwasher can be frustrating, but many common issues can be resolved without immediately calling for service. Understanding the underlying cause of a warning symbol or error code is paramount. This section details practical steps you can take to address frequent problems, from cleaning to resetting the appliance.
Clearing Obstructions: The Strainer and Filters
A significant number of Bosch dishwasher problems stem from clogged filters. The primary culprit is often the Bosch dishwasher strainer, located at the bottom of the wash tub. This component catches food particles and debris, preventing them from circulating and causing blockages. Regular cleaning of the strainer is essential for optimal performance and to prevent errors like E24.
How to Clean the Strainer:
- Ensure the dishwasher is empty and the power is off.
- Locate the filter assembly at the bottom of the tub. It usually consists of a coarse filter and a fine filter.
- Twist and remove the coarse filter, then the fine filter beneath it.
- Rinse all parts under running water, using a soft brush if necessary to remove stubborn debris.
- Reassemble the filters correctly and secure them.
Resetting the Dishwasher
Sometimes, a simple reset can clear temporary electronic glitches that might be causing an error code to display or a warning light to stay on. This is especially useful if the error code is intermittent or if you've addressed a potential cause but the symbol remains.
Perform a Power Cycle Reset: Unplug your Bosch dishwasher from the wall outlet, or switch off the circuit breaker supplying power to the unit. Wait for at least 5-10 minutes, then restore power. This can often clear minor electronic faults and reset the system.
Checking Water Supply and Drainage Hoses
Issues with water intake (E22) or drainage (E24) are frequently linked to the hoses. Ensure the water supply hose is not kinked and the valve is fully open. For drainage, verify the drain hose is correctly positioned, not kinked, and not submerged too deeply in the standpipe, which can cause siphoning. If the hose is connected to a garbage disposal, ensure the knockout plug has been removed if it's a new installation.
When to Call for Professional Help
While many Bosch dishwasher warning symbols and error codes have user-solvable fixes, some indicate more complex internal issues. If you've cleaned the filters, checked hoses, performed a reset, and the E15 leak detection error persists, or if you're uncomfortable performing any of these steps, it's time to contact a qualified appliance repair technician. For models like the Bosch 800 series dishwasher SGV78C53UC, professional diagnosis ensures proper repair without causing further damage.

Regular, simple maintenance tasks can save you from inconvenient breakdowns and costly repairs. By understanding how your dishwasher works and what it needs, you can ensure it performs reliably for years.
Regular Cleaning of Filters and Strainers
As highlighted previously, the Bosch dishwasher strainer and other filters are critical. Food debris, grease, and other particles can accumulate, leading to poor drainage (E24), odors, and reduced cleaning performance. Make it a habit to check and clean the main filter and Bosch dishwasher strainer at least once a month, or more frequently if you tend to wash heavily soiled dishes or have a large household.
Maintaining Optimal Water Flow
Ensure the water inlet valve is fully open and the inlet hose is free from kinks for models like the Bosch 300 series dishwasher SGE53C55UC. Periodically, check the small filter screen located at the connection point of the water inlet hose to the dishwasher itself. Mineral deposits or sediment can clog this, leading to the E22 error or incomplete filling. This simple check can prevent a host of water-related issues.
Using the Right Detergents and Additives
The type and amount of detergent used significantly impact cleaning results and appliance health. Always use detergents specifically designed for automatic dishwashers. Too much detergent can cause excessive sudsing, potentially leading to leaks or component damage. Likewise, regularly refilling the rinse aid dispenser is crucial for proper drying and to prevent spotting, as indicated by the 'Rinse Aid' light. For those in hard water areas, ensuring the salt compartment is filled helps prevent limescale buildup, which can affect heating elements and overall efficiency.
Checking for Leaks and Blockages
Periodically inspect the dishwasher's exterior and the area around it for any signs of moisture. Pay attention to the door seal for any damage or debris that could cause leaks. If you notice water pooling, especially in the base tray, it could trigger the E15 error. Similarly, listen for unusual noises during the drain cycle, which might indicate a partial blockage in the drain hose or pump. Addressing these minor issues proactively can prevent more significant Bosch dishwasher warning symbols from appearing.
Understanding Your Model's Needs
Different Bosch dishwasher series (100, 300, 500, 800) may have slightly different maintenance recommendations or common failure points. For instance, the advanced features on the Bosch 800 series dishwasher might require specific care for sensors or specialized pumps. Always refer to the owner's manual for your specific Bosch dishwasher model. For example, the Bosch 800 series dishwasher SGV78C53UC manual will detail any unique maintenance requirements for its advanced systems.
When Bosch Dishwasher Warning Symbols Signal Professional Help
While many Bosch dishwasher warning symbols and error codes indicate issues you can resolve yourself, some problems require the expertise of a trained technician. Knowing when to escalate is just as important as knowing how to troubleshoot basic faults, ensuring your appliance is repaired correctly and safely.
Persistent Error Codes After Troubleshooting
If you've followed the troubleshooting steps for common codes like the Bosch dishwasher E24 (drainage), E22 (inlet issues), or E15 (leak detected), and the symbol or code reappears, it's a strong indication of an internal component failure. For E15, if draining the base tray doesn't resolve the issue, the leak may be ongoing, requiring a technician to pinpoint and repair the source. For E24, persistent drainage issues after cleaning filters and checking hoses might mean a faulty drain pump or internal blockage.
Unusual Noises or Smells
Warning symbols are not the only indicators of trouble. If your Bosch dishwasher begins making loud grinding, banging, or squealing noises during operation, it could signal a problem with the motor, pump, or wash arms. Similarly, unusual burning smells or the persistent odor of rotten eggs could point to issues with the heating element, pump, or even a blockage that's causing food to decompose. These are often signs that internal components are failing or have failed.
Water Leaks Not Resolved by Basic Checks
While the E15 code specifically alerts to water in the base tray, a visible leak from the front, sides, or bottom of the dishwasher that isn't related to a specific error code also warrants professional attention. This could be due to a damaged door seal, a cracked tub, a faulty water inlet valve, or a loose hose connection that you cannot easily access or repair. Continuing to run a leaking dishwasher can cause significant water damage.
Complex Electronic or Sensor Failures
Modern Bosch dishwashers, especially higher-end models like the Bosch 800 series dishwasher, rely on sophisticated electronic control boards and multiple sensors. If the control panel is unresponsive, displaying random symbols, or if multiple error codes appear in quick succession, it might indicate a complex electronic fault. Diagnosing and repairing such issues requires specialized knowledge and equipment that only a qualified technician possesses.
Document Everything Before Calling: When you do need to call for service, be prepared. Note down the exact error code or symbol displayed, the symptoms you're experiencing (e.g., noises, leaks, cycle behavior), and any troubleshooting steps you've already taken. This information is invaluable for the technician and can help expedite the repair process.
When to Replace Rather Than Repair
For older appliances, or in cases where the repair cost approaches the price of a new unit (especially for models like the Bosch 100 series dishwasher, which are more budget-focused), replacement might be the more economical choice. Weigh the cost of the repair against the expected remaining lifespan of the appliance and consider the efficiency and features of newer models.
