A dishwasher is a staple appliance in many households, making life easier and more convenient. However, when an error code appears on the dishwasher display, figuring out what it means and how to fix it can be frustrating.
One of the most common errors for Bosch dishwashers is the E15 error code. This error code signifies that there is excess water in the dishwasher base of the machine, which can cause damage to both the machine and the surrounding areas.
This article will explore the 10 possible causes and solutions of the E15 error code to help you better understand and deal with the situation.
Causes of Bosch Dishwasher Error Code E15
If you own a Bosch dishwasher, chances are you have encountered the dreaded E15 error code. This error code indicates a water leakage somewhere in the dishwasher, which needs to be addressed before the dishwasher can resume normal operation.
There are different common causes of the E15 error code in Bosch dishwashers. Let’s take a look at 10 possible causes.
1. Excess Dishwasher Soap Or Detergent
Too much detergent can cause issues with your dishwasher, resulting in frustrating error messages and even costly repairs.
Specifically, if you use too much detergent, you might notice too many suds in your dishwasher, triggering an E15 error code.
2. Leaking Water Tank
A dishwasher leaking water tank could also be the cause of an E15 error code. This can happen due to a faulty seal or hose and should be checked as soon as possible.
The internal water tank should be replaced or repaired if a dangerous leak is present to prevent further problems.
3. Sump Basin Leak
The sump basin can also become blocked or cracked, which can cause an E15 error code. A clogged filter may be the culprit and should be cleaned or replaced immediately.
4. Broken Fixtures
Certain fixtures within the dishwasher can become defective and cause an E15 error code. These include the heating element, dishwasher drain pump, fill valve and drain valve.
If any of these are malfunctioning, they should be replaced or repaired as soon as possible.
5. A Defective Sprinkler
A defective water sprinkler can cause an error code E15. This can occur due to a blocked filter, worn-out motor, or faulty pump.
If the issue persists after cleaning the filters and replacing any parts, contact the Bosch customer service team for assistance.
6. A Faulty Water Hose
When it comes to your dishwasher, a faulty water hose can be a major problem. Not only can it cause the machine not to work properly, but it can also lead to water damage in your home.
If you’re experiencing the Bosch dishwasher error code E15, it’s possible that a faulty water hose is to blame.
7. Blocked Drainage System
A blocked drainage system can pose severe implications to your household, causing much inconvenience and frustration. Not only can this lead to unpleasant odors and stagnant water buildup, but it can also cause the E15 error code to appear, indicating a fault in the dishwasher system.
Such issues can result in costly repair bills or even require a complete dishwasher replacement. Thus, keeping your drainage system clear and functioning smoothly is crucial to avoid such problems.
8. Faulty Pressure Switch
The pressure switch regulates the flow of water into the dishwasher. A faulty switch can prevent water from entering the dishwasher, leading to the E15 error code.
Check the anti-flood switch for any dishwasher faults or damage, and replace it if necessary.
9. Malfunctioning Flow Meter
The flow meter measures the amount of water entering the dishwasher. If it is not working correctly, it can cause an E15 error code to appear.
The flow meter should be checked for blockages or malfunctions and replaced or repaired if necessary.
10. Inadequate Ventilation
Inadequate ventilation can prevent the dishwasher from receiving sufficient water, leading to the E15 error. Check the ventilation system and ensure that it is properly installed and free from obstruction.
How to Fix Bosch Dishwasher Error Code E15
Once you have identified the cause of your dishwasher’s error code E15, it is crucial to quickly take action to prevent further damage. Here are some steps you can take to fix the issue:

Lastly, ensure adequate water flow to the sprinkler by checking the water inlet valve and cleaning it if needed.
6. Check Water Hoses and Connections
The dishwasher’s water hoses and connections provide the essential water supply needed to keep it running. If any of the hoses become loose or disconnected, it can result in an E15 error code.
To inspect the appliance hoses and connections, start by disconnecting the power supply to your dishwasher. Carefully remove any covers on the water hoses and check them for any potential leaks, wear, or damage.
If any issues are detected, replace the hose as soon as possible. You should also check to make sure the water hoses and connections are firmly connected and tight.
7. Inspect the Drainage System

You should also look for any visible damage to the drainage system and replace it if necessary. Lastly, ensure the water flow to the drainage system is adequate by checking the water inlet valve and cleaning it if needed.
8. Check the Pressure Switch
To check the pressure switch, disconnect the dishwasher from the power source and access the pressure switch.
Once you have identified the pressure switch, use a multimeter to measure its resistance value. If the resistance value is not within the range specified by your dishwasher’s manufacturer, it may be time to replace the pressure switch.
9. Check the Flow Meter
If the flow meter becomes blocked or damaged, it can cause the dishwasher to display an E15 error code. Disconnect the power supply to your dishwasher to inspect the flow meter and carefully remove the lower rack.
