In the next section, we will discuss the different problems and their solution, which could help you fix the E15 error code in your Bosch dishwasher. 

What causes the E15 error code in the Bosch Dishwasher?

There are various reasons that can encounter an E15 error code in the Bosch dishwasher.

To fix the E15 error code, first, we need to identify the exact issue behind the problem.

Once you identify the problem, you can quickly fix the E15 error code from your dishwasher.

Here we will discuss 5 issues that could encounter the E15 error code in your dishwasher. 

Broken Fixture

Bosch dishwasher is equipped with several fixtures that help the dishwasher to pass water into the dishwasher.

The dishwasher requires to complete the cycle and clean the dishes. A dishwasher more than 10 years old can be eroded over time.

If you have been using the dishwasher for a while, it can break over time. 

A tiny crack on the fixture can also create leakage in the dishwasher. The downside of the broken fixture is it can’t be repaired; you need to replace it with a new one.

Solution 

Before considering this problem, I recommend locating the fixture in your dishwasher.

Once you locate the fixture, make a proper inspection and see if there is any kind of cracks or not. If there is a crack, you need to replace it with a new one. 

If you don’t know how to check broken fixtures in the Bosch dishwasher, I recommend calling technicians.

To replace you should have proper tools and gadgets. Therefore, it is better to call dishwasher technicians or anyone who has expertise in repairing dishwashers. 

Detergent

Detergent is another major issue that can cause an E15 error code in the dishwasher.

If you use a detergent that produces more suds, it is more likely to create leakage in the dishwasher.

To run the dish or wash cycle, you need to put detergent in the dishwasher. 

Similarly, if you are using the wrong detergent in your dishwasher for a long period, you can encounter an E15 error code in your dishwasher.

When the dishwasher gets filled with suds, it can force water to drip into the base of the dishwasher and can trigger the E15 error code in the Bosch dishwasher. 

Solution

As mentioned earlier, you should avoid using a detergent that produces more suds during the wash cycle.

Similarly, if you were using the wrong detergent, then I recommend you reset your dishwasher and run an empty wash cycle.

Doing this will clear out all the remaining detergent from the soap dispenser and the dishwasher. 

Check the dishwasher user manual if you don’t know which detergent to use. There you will find everything about dishwasher detergent.

You can also visit the Bosch dishwasher official website to know more about the detergent and dishwasher model.  

The broken tub or leaky sump

A broken tub or leaky sump is another issue that causes the E15 error code in the dishwasher. The sump basin is located at the bottom of the dishwasher.

The E15 error code means there is water at the bottom of the dishwasher. The main function of the sump is to collect water that enters the pump. 

The sump is lined with a rubber seal that prevents water from entering the dishwasher.

When the sump seal is torn out, it will fill water inside the dishwasher tub and create overflooding in the dishwasher.

I recommend you make a proper inspection of the dishwasher tub and sump seal in order to locate the exact issue behind the E15 error code in the Bosch dishwasher. 

Solution

The first thing that you can do is ensure that the screw holding the dishwasher sump should be tight.

If the screw is loose, tighten it up using screwdrivers or pliers. If the leak persists, remove the dishwasher from the kitchen cabinet. 

After this, bend the dishwasher backward and remove the lower access panel of the dishwasher.

Now, you can easily access and make an inspection of the sump basin.

If there is a crack or any kind of leakage, consider replacing it with a new one. You can contact dishwasher technicians to replace the sump basin with a new one. 

Loose or broken drain hose

Bosch dishwasher is equipped with lots of hosen that pass water inside the dishwasher.

If your dishwasher’s drain hose is cracked or loose, there is a high chance of water leakage at the bottom of your dishwasher.

When the safety switch sensed water, it triggered the E15 error code in the dishwasher. 

The drain hose is located at the bottom of the dishwasher. One drain hose is connected to the dishwasher drain pump, and another is connected to the garbage disposal. You can quickly inspect the crack by removing the dishwasher from the kitchen cabinet. 

Solution

In some cases, a cracked drain hose also causes the issue of leakage in the Bosch dishwasher.

Therefore, I recommend you to make a proper inspection at the bottom of the dishwasher and check for cracks if present.

Follow the below step-wise instruction to check the Bosch dishwasher drain hose. 

1.     Remove the water supply pipe and power cord from the dishwasher. 

2.    Now remove the screw that is holding the dishwasher in the cabinet. After removing the screw, you can easily remove your dishwasher from the kitchen cabinet. 

3.    Bend the dishwasher backward, and there you need to remove the lower access panel to access the dishwasher drain hose. Remove the screw that is holding the lower access panel on the dishwasher. 

4.    After this, you will see a drain hose connected to the drain pump; now, remove the drain hose from the pump. 

5.     Clean all the clogged food particles from the hose and see if there is any kind of crack or not. 

6.    If there is a crack, replace the drain hose.

After this, reinstall all the dishwasher parts and put them inside a kitchen cabinet.

Turn on the water supply and power supply and see if the dishwasher is showing an E15 error code or not. If the problem persists, check the next issue. 

Faulty float switch

Float Switch is another major reason that can cause leakage in the dishwasher. The float switch prevents the dishwasher from overloading and flooding.

It is directly connected to the dishwasher control panel and provides water information in the dishwasher tanks. 

When the water is filled, the control panel instructs to turn off water loading into the dishwasher.

Most of the dishwasher float switch is located just beside the dishwasher’s control panel. In some dishwashers, it is located at the bottom of the dishwasher. 

Solution 

If the float creates over flooding and triggers the E15 error code in the dishwasher.

Here is the step-wise instruction to check and replace the dishwasher float switch with step-wise instruction. 

1.     Unplug the power cord and water supply in your dishwasher. 

2.    Open the dishwasher door and remove the mounting bracket screw from your dishwasher. You may also need to remove the leveling leg locking screw and adjust the legs to lower the dishwasher. 

3.    Remove the dishwasher from the kitchen cabinet.

4.    You will see a float switch connected with a wire in the dishwasher at the back of the dishwasher. 

5.     If there is water just beneath the dishwasher float switch, you need to replace your float switch. 

This is how you should replace your dishwasher float switch. I hope that the method has worked well in your model. If the problem persists, there might be another issue with your dishwasher. 

What to do if the error persists?

The above-discussed solution might not work in all the models of Bosch dishwashers.

If the above-discussed none of the problems exists in your dishwasher and if you are unable to fix the E15 error code. Then, don’t worry, I recommend you to call the Bosch dishwasher service center.
