Key Takeaways

• The Bosch dishwasher error code E15 indicates water accumulation in the base of the dishwasher, often caused by leaks.

Understanding the Bosch Dishwasher E15 Error

When your dishwasher displays the Bosch E15 error code, it is signaling an issue with excess water in the base pan. This error is part of the dishwasher’s built-in anti-flood system, which helps protect your appliance and home from water damage. While the presence of water in the base often triggers the error, the underlying cause could vary.

In most cases, the error is triggered by leaks or malfunctions in certain parts of the dishwasher, including the door seal, water inlet valve, and hoses. Identifying and fixing the root cause is crucial to ensure the error doesn’t recur and to avoid further damage to the appliance.For expert help, you can reach out to Smart Appliance Services.

Causes of Bosch Dishwasher E15 Error

There are several potential causes behind the Bosch dishwasher fault E15. If you’re dealing with this issue and aren’t sure where to start, Bosch Appliance Repair can provide the expertise you need to get your dishwasher back in working order. Here are the most common culprits:

Leaky seals or gaskets

Over time, the door seals or gaskets around your dishwasher’s door can wear out. If the seals are damaged or degraded, water can leak out during a wash cycle and pool at the bottom of the dishwasher. This water accumulation is usually what triggers the Bosch dishwasher fault code E15. Replacing the door seal is often a quick and easy fix for this issue.

Water inlet valve issues

The water inlet valve is responsible for regulating the flow of water into the dishwasher. If this valve malfunctions, it may allow too much water to enter the appliance, causing it to overflow into the base. This excess water can trigger the Bosch error code E15. A faulty inlet valve will typically need to be replaced to resolve the issue.

Leaking hoses 

Damaged or improperly secured hoses can cause water to leak from the dishwasher. Leaks from the hoses are not always immediately noticeable but can accumulate in the base of the dishwasher over time. Check all the hoses connected to your dishwasher to make sure they are secure and in good condition. Replace any damaged hoses as needed.

Control board or safety switch malfunctions

In some cases, the Bosch dishwasher error E15 may be caused by a malfunctioning control board or safety switch. These components are responsible for detecting the water level in the dishwasher, and if they fail, they can trigger the error even when there is no visible leakage. A malfunctioning control board or safety switch can be difficult to diagnose and may require professional attention to repair. For expert assistance, consider Bosch Dishwasher Repair.

How to Fix Bosch Dishwasher E15 Error

If you’re encountering the E15 error on your Bosch dishwasher, there’s no need to worry. Simply follow these step-by-step instructions to troubleshoot and possibly resolve the issue on your own.

Try to clear the E15 error code

Sometimes the Bosch dishwasher E15 may be caused by a minor glitch or power surge. A simple reset may clear the error. Here’s how you can perform a hard reset:

• Disconnect the dishwasher from its power source by either unplugging it or turning off the circuit breaker.
• Wait for at least five minutes to allow the system to reset.
• Restore power to the dishwasher and check if the error code has cleared.
• If the code disappears, run a test cycle to make sure the dishwasher functions properly.

Remove water from the base

If the error code persists, there’s likely excess water in the base of the dishwasher. You’ll need to drain it to clear the error. Follow these steps to do so:

• Turn off the power to the dishwasher and disconnect the water supply.
• Remove the lower front panel or kickplate to access the bottom of the appliance.
• Tilt the dishwasher back at a 45-degree angle to allow the water to drain out. You may want to use towels or a shallow pan to catch any water that spills out.
• After tilting the dishwasher for a minute or so, restore power to the appliance and check if the error code has cleared.
• Run a test cycle to ensure the dishwasher operates without issues.

Inspect and replace the door seal

If you suspect that a leaky door seal is the cause of the Bosch error code E15, you’ll need to inspect the door seal for visible damage. Here’s how you can replace it:

• Open the dishwasher door and inspect the seal for any cracks, tears, or signs of wear.
• If you find any damage, purchase a replacement seal from a Bosch-certified supplier.
• Remove the old seal by gently pulling it off the door frame.
• Install the new seal by pressing it into place along the door’s edge, ensuring it fits snugly.
• Close the door, and test the dishwasher to see if the error code has been cleared.

Inspect the water inlet valve and hoses

Next, check the water inlet valve and hoses for any damage or leaks:

• Turn off the water supply to the dishwasher.
• Disconnect the water supply hose from the dishwasher’s inlet valve.
• Check the inlet valve for any visible damage or leaks. If the valve appears faulty, it will need to be replaced.
• Inspect the hoses for kinks, tears, or other issues. If you find any problems, replace the hoses as necessary.
• Once everything is inspected and repaired, reconnect the hoses and test the dishwasher.

Reset the water level safety switch

If the error persists, you may need to reset the dishwasher’s water level safety switch:

• Disconnect the power to the dishwasher and remove the kickplate at the bottom of the appliance.
• Use a towel to dry up any remaining water in the bottom of the pan.
• Locate the float switch (refer to the manual for your model’s specific location).
• Reset the switch by pressing the button or repositioning the float. Ensure it’s working correctly.
• Reassemble the dishwasher, restore power, and run a test cycle to check if the error code is cleared.
