Error codes for Bosch Dishwasher

  • Product Types: Dishwasher

Please do take care to read the information thoroughly as it is there to help you understand fault codes and to keep you safe. There are also some help, tips and hints with a lot of the fault codes published here that you usually will not find anywhere else and, as we learn, we add more information so if you can't find what you need please ask in the forums.

Before using this section please understand that fault or error codes are used as a diagnostic aid, they are not a replacement for diagnostic skill on the part of the person repairing the product and are not in any way usually going to point to the precise component that is faulty. All they do is give you an idea of where to start looking for the fault.

Bosch Dishwasher Error codes

These error code explanations can help you diagnose a problem with your Bosch Dishwasher.

E0

No fault codes are recorded

Issue:

E1

Heating problem

Issue:
Check the water fill level. If water level is too low, the heater won’t turn on. If the water level is okay, the flow switch or the heater could be defective.

E3

Not filling

Issue:
If the water supply cut-off valve for the dishwasher is fully open and the dishwasher still won’t fill, shut off the water supply, unplug the dishwasher, disconnect the fill line and check whether the screen in the water inlet valve is clogged. If it’s clogged, replace the water valve—don’t just clean the screen, because debris could fall into the valve body, prevent the valve from closing, and cause flooding. If the dishwasher still won’t fill, have a service technician diagnose and repair the dishwasher.
