How To Reset The Bosch Dishwasher Error Code E24?

20.12.2023

Bosch is recognized as a manufacturer of quality and reliable dishwashers. However, wear and tear will still occur over time, resulting in a variety of troubles. If your Bosch dishwasher shows the error code E24, it means that it’s not draining correctly. In this article, Jacob Dillard, an engineer at Appliance Repair Expert, will tell us about this error and how to solve it.

Bosch Dishwasher Filter

A blocked filter is frequently the source of the problem. You need to remove the appliance’s filter and wash it thoroughly. If the error remains after that, the cause may be the drain hose has been blocked:

  • Check the drain hose and make sure it is not kinked or damaged.
  • Check the trap connection and make sure it is tight.
  • Check both for debris and food residue, preventing water from draining.

These were the most common parts you should check to repair the device yourself, and after restarting the dishwasher, the error code E24 should disappear. 

Advanced technical problems that might cause the code to appear.

Ways To Fix Error Code E24 On The Bosch Dishwasher

  • Clean the pump impeller. Food remains trapped between the impeller and the pump casing, increasing the mechanical resistance to rotation. The system detects this as a pump failure. The dishwasher switches off, and error E24 appears. Clearing the shaft of wound-up debris, cleaning the impeller and servicing the pump bushings are all options to solve the problem;

  • Repair or replacement of the drain pump. Asynchronous motors run the pumps of the third-generation models of Bosch dishwashers, the current in the windings is sensitive to changes in the load. To fix the problem, you may need to service or replace the pump, as well as repair or replace the impel;

  • Repair or replacement of the circulation pump. The situation when the Bosch dishwasher error E24 appears can be caused by factors not related to the drainage system. Worn ceramic bushings in the circulation pump, deformation of the plastic pump casing in which the tubular electric heating element is integrated, leaks, and fluid leakage are all defects that can cause problems. The exact cause of the malfunction can only be determined by a qualified technician.

  • Repair or replacement of the control module. This is the rarest but still the most common cause of the Bosch dishwasher error E24. A malfunctioning electronic unit can disrupt the normal functioning of the dishwasher and cause this error. An experienced technician can repair or replace the faulty control module (unit, board).

The most common solution to a drain problem requires cleaning the dishwasher’s filter and drain hoses. Still, there are several additional reasons why a Bosch dishwasher generates error code 24, including a clogged pump impeller, faulty drain or circulation pumps, and faulty control modules.
