Troubleshooting Bosch Dishwasher E24 E25 Error Codes

For a dishwasher to work correctly, it must let water in and out of the machine without any problems. If the machine ever struggles to drain the dirty water out, it’ll start to display an error code. On Bosch dishwashers, the error codes E24 and E25 are triggered by a failure to drain water.

If you see the error code E24 or E25 on your Bosch dishwasher, it’s because the appliance cannot drain water out of the machine. Even though both error codes point to a draining failure, each of them points to a different root cause. E24 suggests that the drain filter is blocked, while E25 suggests that the root problem is the drain pump.

In this article, we will take a closer look at both error codes and their possible causes. We’ll also look at how you can fix the problem and return the machine back to good working order.

Let’s get started.

When the E24 or E25 error codes appear on your Bosch dishwasher, that’s an indicator that dirty water cannot drain out from the machine. While the problem may be similar, the difference between the two codes is the root cause behind that problem.

The E24 error code on your Bosch dishwasher means that the failure to drain is related to the drain filter. 

On the other hand, the E25 error code points to the root cause being related to the drain pump.

We’ll dive deeper into the drain pump, air gap, impeller cover, and drain pipes or hoses in the following section.

As said earlier, the E24/E25 error codes simply mean the appliance cannot drain water out of the machine. There could be many causes for this, such as:

Dishwashers, whether they’re made by Bosch or any other manufacturer, typically rely on several pumps to function correctly. One of those is known as the drain pump, and it’s typically located towards the bottom on the inside of the dishwasher.

The purpose of the drain pump is straightforward: it helps remove all of the water from inside the dishwasher by directing its flow to the drain hose or pipe.

Why it fails:

In this situation, there’s a strong possibility that the drain pump has gotten jammed by a foreign object. Even though the dishwasher’s basin has a filter on top of it, hard foreign objects (like broken glass or porcelain) may have gotten past it and found their way into the drain pump. 

When that happens, the drain pump will not be able to let water flow out.

Besides that, the drain pump might become jammed by food bits built up inside of it. Remember: the dishes that you load into the machine are dirty, and they’ll still have food bits stuck to them even if you rinsed them off first.

Over time, those tiny bits can build up inside the dishwasher, especially in the lower areas like the basin and drain pump.

How to fix:

To solve this problem, you’ll need to clear whatever is jamming up the drain pump. Firstly, you must shut off the power and water supply to the appliance. That will prevent any injuries or flooding while you work on the machine.
