Bosch Dishwasher Error Codes

Bosch Dishwasher Error code E23, E24, E25

Bosch dishwashers have a well-earned reputation for efficiency and performance, but like any complex appliance, they can sometimes run into issues. When it comes to Bosch dishwasher error codes, E23, E24, and E25 are among the common culprits. These error codes typically indicate a problem with the dishwasher’s drainage system, often pointing to a drain pump failure or a clogged drain hose. In this article, we will delve deeper into what these error codes mean and provide detailed steps on how to diagnose and resolve these issues.

Error Codes E23, E24, and E25: Drain Pump Failure or Clogged Drain Hose

When your Bosch dishwasher displays error codes E23, E24, or E25, it’s essential to understand that they are all related to the dishwasher’s ability to drain water effectively. Here’s what each code signifies:

  • E23: This error code generally indicates that there is a drain pump failure. The drain pump is responsible for expelling wastewater from the dishwasher, and if it’s not functioning correctly, you’ll encounter drainage issues.
  • E24: Bosch dishwasher error code E24 typically points to a clogged drain hose. If the drain hose is obstructed or improperly installed, it can prevent proper water drainage.
  • E25: Similar to E24, error code E25 is often associated with drainage problems caused by a clogged drain hose.

Steps to Diagnose and Resolve the Issues:

  1. Check the Drain Hose: Begin by inspecting the drain hose. Ensure it is properly installed and not kinked or bent, which could obstruct the flow of water. Remove any visible clogs or debris from the hose.
  2. Examine the Drain Pump: If the drain hose appears to be in good condition, it’s time to check the drain pump. Open the dishwasher’s kickplate, and you’ll typically find the drain pump. Listen for any unusual noises when the dishwasher is draining, as this could indicate a mechanical failure. If there are no sounds, it might be an electrical failure. You can test the pump’s electrical functionality using a multimeter continuity test.
  3. Clean the Filters: A common cause of drainage issues is clogged filters within the dishwasher. Remove and clean the filters regularly to prevent blockages that can lead to error codes.
  4. Unclog the Drain Line: If you suspect that there’s a clog further down the drain line, you may need to remove the dishwasher and inspect the drain line for any blockages.
  5. Reset the Dishwasher: After making any necessary adjustments or clearing clogs, reset your Bosch dishwasher by turning it off and unplugging it for a few minutes. Then, plug it back in and turn it on to see if the error codes have disappeared.
