End your dishwasher nightmares: how to decipher bosch error messages with ease

Bosch dishwashers are renowned for their reliability and efficiency, but like all appliances, they can occasionally encounter issues. When this happens, deciphering the error messages displayed on the control panel can be a crucial step towards resolving the problem. In this comprehensive guide, we delve into the most common error messages for Bosch dishwashers, providing clear explanations and troubleshooting tips to help you restore your dishwasher to optimal performance.

E01: Water Supply Issue

This error indicates that the dishwasher is not receiving an adequate water supply. Check if the water inlet hose is kinked or blocked, and ensure that the water supply valve is fully open. If the problem persists, there may be an issue with the water pressure or the water supply itself.

E02: Water Drain Issue

E02 error message signifies that the dishwasher is unable to drain water effectively. Inspect the drain hose for any blockages or kinks, and clean the drain filter located at the bottom of the dishwasher. If the problem remains, it could be due to a faulty drain pump or a clogged drain line.

E03: Overfill Issue

This error occurs when the dishwasher has taken in too much water. Check if the water inlet valve is closing properly and if the pressure switch is functioning correctly. If the problem persists, it could indicate a faulty control board or a malfunctioning pressure switch.

E04: Temperature Sensor Issue

The E04 error message indicates a problem with the dishwasher’s temperature sensor. This sensor monitors the water temperature and ensures that it reaches the desired level during the wash cycle. If the sensor is faulty, the dishwasher may not heat the water properly or may overheat.

E05: Heating Element Issue

This error message signifies a problem with the dishwasher’s heating element. The heating element is responsible for heating the water during the wash cycle. If the heating element is faulty, the dishwasher may not heat the water at all or may not heat it to the desired temperature.

E06: Circulation Pump Issue

The circulation pump is responsible for circulating water throughout the dishwasher during the wash cycle. If the circulation pump is faulty, the dishwasher may not be able to clean the dishes effectively or may not be able to drain the water properly.

E15: Door Lock Issue

The E15 error message indicates a problem with the dishwasher’s door lock. The door lock ensures that the door is securely closed during the wash cycle. If the door lock is faulty, the dishwasher may not start or may stop mid-cycle.
