How to Read Bosch Washer Error Codes

Bosch washer error codes can be read differently depending on the type of machine you have.

Digital Display

For models with a digital display, error codes will begin with an 'E' or 'F' followed by a two-digit number. These codes help to pinpoint the exact issue your machine might be facing.

Older Machines

In older models without a digital display, flashing lights indicate the error code. The pattern and color of the lights correspond to specific issues and can be cross-referenced with your machine's manual.

Understanding these codes is the first step towards troubleshooting and fixing any issues with your Bosch washing machine.

How to Read Bosch Washer Error Codes

Understanding and interpreting Bosch washer error codes can be the key to identifying what's going wrong with your appliance. Here's a simple guide to reading these codes, broken down into two categories based on the model and display type.

Digital Display: E or F followed by a Two-Digit Number

Most modern Bosch washing machines come with a digital display that shows error codes beginning with an "E" or "F," followed by a two-digit number. For example:

• E3 or F3: Door lock error
• E18 or F18: Pump or drain timed out due to blocked drain hose

These codes are usually quite clear and will relate directly to specific issues within the machine.

Older Machines: Flashing Lights Indicate the Error Code

For older Bosch models without a digital display, understanding the error code can be a bit trickier. The machine might use flashing lights, sounds, or a combination of both to indicate a specific error. The manual for your particular model will explain what each flashing light or sound pattern means.

Keep in mind that not all errors will completely halt the machine's operation. Some may just be warnings or informational codes that don't require immediate action.

Quick Tips:

• Note the Error Code: As soon as you see an error code, write it down. This will be invaluable for troubleshooting or if you need to call a technician.
• Consult the Manual: Your washer's manual will usually contain a detailed explanation of each code and might include troubleshooting tips.
• Perform a Basic Inspection: Sometimes, error codes can be caused by simple issues like a loose connection or clogged filter. Check these first before diving into more complex troubleshooting.

Figuring out what these error codes say might initially seem overwhelming, but with this guide and your manual in hand, you'll be well-equipped to diagnose and resolve many common problems.
