Washer Bosch Error Codes

When your Bosch washing machine starts acting up, the first thing you should do is check if it’s displaying any error codes on its screen. These codes are a way for the appliance to communicate specifically what’s failing in its system, allowing you to identify and, in many cases, solve the problem without having to immediately call for technical service.

But, what does each code mean? Below, we present a detailed table with the most common error codes for Bosch washing machines, their description, and recommended solutions. Before diving into details, it’s important to understand some concepts:

  • Electrical system: Refers to any component related to electricity in the washing machine, such as the plug, internal wiring, or control panel.
  • Door lock: It’s a safety mechanism that prevents the washing machine door from opening during certain washing cycles to avoid accidents.
  • Inlet valve: It’s the part of the washing machine that controls the flow of water into the appliance.
  • Inlet filter: A small device located at the water hose connection to the washing machine, designed to catch particles and prevent them from entering the machine.

With these concepts clear, let’s look at the error codes:
