Understanding the Bosch Dishwasher E17 Error Code
If you’ve noticed your Bosch dishwasher displaying the E17 error code accompanied by a flashing indicator, it signifies a critical issue related to water levels within the machine. This error can halt your dishwasher’s operation, causing inconvenience and potential water damage if left unaddressed. Recognizing what this code means is essential for timely troubleshooting and restoring your appliance’s functionality.
The E17 error specifically indicates that the dishwasher has detected an overflow or excessive water accumulation inside the tub. This safety feature prevents further water intake or operation to avoid spills and damage to surrounding areas. When this error appears, your dishwasher may stop mid-cycle or refuse to start altogether. Usually, you’ll notice water pooling at the bottom of the unit, unusual splashing noises, or the cycle simply halting unexpectedly.

Decoding the E17 Error: What Does It Mean?
The E17 code is a diagnostic message that points to an issue with water regulation inside your dishwasher. Essentially, it indicates an abnormal water level—either too high or overflowing—triggering the machine’s safety protocols. This prevents further operation until the problem is resolved.
Understanding the significance of the E17 error is crucial. It serves as an early warning to potential issues like leaks, blockages, or malfunctioning components that can cause water damage or operational failures if ignored. Addressing this promptly helps maintain your dishwasher’s longevity and safety.
Primary Causes of the E17 Error in Bosch Dishwashers
The appearance of the E17 error typically correlates with problems affecting water management within the appliance. Below are the most common culprits:
1. Faulty Float Switch
The float switch acts as a water level sensor, positioned within a float chamber that moves freely with the water level. If this switch malfunctions or becomes stuck, it can send false signals to the control board, causing the dishwasher to think there’s an overflow even when there isn’t. This leads to the E17 error being triggered and the cycle being halted to prevent flooding.
2. Clogged or Blocked Drain Hose
The drain hose is responsible for removing excess water from the dishwasher after each cycle. When obstructed by debris, food particles, or kinks, it hampers proper drainage, leading to water pooling inside the tub. This excess water can trigger the water level sensor to detect an overflow, resulting in the E17 error.
3. Dirty or Obstructed Dishwasher Filter
The filter traps food debris and prevents it from reaching the drain pump or clogging the hoses. Over time, debris buildup can restrict water flow, impair drainage, and cause inaccurate water level readings. Regular cleaning of the filter is essential to maintain optimal operation and prevent false overflow detection.
4. Malfunctioning Drain Pump
The drain pump’s role is to evacuate dirty water after the wash cycle. If it fails or becomes blocked, water remains in the tub, leading to an overfilled condition. Common issues include electrical faults, impeller damage, or debris accumulation, all of which can cause the E17 error.
5. Water Inlet Valve Problems
The water inlet valve controls the inflow of water into the dishwasher. If defective or stuck open, it can cause continuous water entry, leading to overfill conditions. Conversely, a faulty valve that doesn’t open correctly prevents proper filling, but in the context of E17, an open valve is often implicated, causing overflow and triggering the error.
Resetting Your Bosch Dishwasher with E17 Error
Sometimes, a simple reset can clear the error message and restore normal operation. Here’s a straightforward reset procedure:
- Unplug the dishwasher from the power outlet and wait for at least 5 seconds.
- Reconnect the power supply and turn the dishwasher back on.
- Check if the error code clears and the cycle resumes normally.
Step-by-Step Solutions to Fix the E17 Error
If resetting doesn’t resolve the problem, you may need to inspect and repair specific components. Below are detailed troubleshooting steps for common causes:
1. Repair or Replace the Faulty Float Switch
Accessing the float switch involves removing the lower front panel:
- Use a Phillips screwdriver to unscrew the panel at the bottom of the dishwasher.
- Locate the float chamber inside the tub; it contains the float switch with a small arm floating freely.
- Gently remove the switch by unclipping it, then inspect for debris or damage.
- Clean the switch and its chamber with a damp cloth to remove buildup.
- If the switch appears defective, replace it with a compatible part.
2. Clear Blockages in the Drain Hose
Proper drainage is vital:
- Pull out the dishwasher carefully to access the drain hose at the bottom.
- Loosen clamps with pliers and detach the hose from both the dishwasher and sink drain.
- Inspect for kinks or bends; straighten if necessary.
- Use a snake or warm water to dislodge any clogs inside the hose.
- Reattach the hose securely and test the operation.
3. Clean or Replace the Dishwasher Filter
Filters are typically located at the bottom front of the dishwasher:
- Open the filter cover and carefully remove the filter assembly.
- Rinse the filter under running water, removing trapped debris.
- Reinstall the cleaned filter or replace it if damaged.
4. Address Issues with the Drain Pump
The drain pump is accessible by removing the lower panel:
- Inspect the pump and impeller for debris, damage, or obstructions.
- Clean around the pump inlet and outlet to ensure free flow.
- If the pump is faulty or damaged, contact a professional technician for repair or replacement.
5. Fix or Replace the Water Inlet Valve
Access the inlet valve by removing the lower panel:
- Check electrical connections for looseness or corrosion.
- Inspect the valve for visible damage or leaks.
- If defective, replace the inlet valve with an OEM-approved component.
Final Recommendations and Precautions
While some troubleshooting can be performed independently, always prioritize safety. Disconnect power before working on electrical components, and if you’re unsure or uncomfortable with repairs, seek professional assistance.
Proactive maintenance, such as cleaning filters and inspecting hoses regularly, can prevent the E17 error and extend the lifespan of your dishwasher.
Conclusion
The Bosch dishwasher E17 error is a warning signal indicating water level anomalies, often caused by issues with the float switch, drainage system, filters, pump, or inlet valve. Addressing these problems promptly ensures your appliance operates efficiently and prevents potential water damage.
For minor issues, simple resets or cleaning may suffice. However, complex repairs involving electrical components or internal parts should be handled by qualified technicians or Bosch support to ensure safety and proper resolution.
