Bosch Dishwasher E10 Error Code Explained: Meaning, Causes & Fixes

 
Check the Water Supply and Inlet Valve
 

• Ensure the water tap supplying the dishwasher is turned fully on and that there is adequate water pressure available.
• Inspect the water inlet hose for kinks or clogs. Remove the hose if necessary and clean out any debris or sediment that may be obstructing the water flow.
• Check the inlet valve for signs of wear or malfunction. If the valve is faulty, consider replacing it to restore proper water intake.

 
Clean and Clear the Filters and Drain System
 

• Remove the bottom rack of the dishwasher to access the filter assembly. Take out the filter and rinse it thoroughly under running water to eliminate any debris or food particles.
• Inspect the area around the filter for any blockages that could restrict water flow. Use a soft brush if needed to dislodge stubborn residue.
• Examine the drain hose for bends or blockages. Disconnect it carefully and clean out any obstructions that might be preventing proper drainage.

 
Inspect the Drain Pump and Its Components
 

• Remove any removable components that allow for better access to the drain pump. Check the pump impeller for any foreign objects that could be causing a blockage.
• If debris is found, carefully extract it by hand or using a small tool. Ensure that all moving parts of the pump can rotate freely without resistance.
• Confirm that the pump is securely attached and all connectors are properly in place; loose wiring or clamped hoses can disrupt the pump’s function.

 
Reset and Test the Dishwasher
 

• After cleaning and inspecting the water inlet, filters, drain hose, and pump, unplug the dishwasher from the power outlet or switch off the circuit breaker for at least one minute.
• Restore power to the appliance and run a short diagnostic or rinse cycle to determine if the error persists.
• If the error code is no longer displayed, run a full wash cycle to verify that the system is operating normally. If the error appears again, further investigation may be required.

 
Examine the Control Board and Sensor Connections
 

• Check the wiring harnesses connected to the control board and sensors for any signs of damage, loose connections, or corrosion. Secure any loose connections properly.
• If a sensor appears faulty or damaged, it may need to be replaced to ensure accurate error detection and proper functioning of the dishwasher’s cycle.
• After securing wiring and sensor connections, reset the dishwasher again to test if the E10 error has been resolved.
