Bosch Dishwasher Error code E05

The E05 error code on your Bosch dishwasher is an indication of a problem related to the water switch Triac on the main control board. In some instances, it may also signal issues with the float or the float switch. Let’s break down these potential causes:

1. Water Switch Triac Fault:

The most likely reason for the E05 error is a malfunction in the water switch Triac on the main control board. This component is responsible for regulating the water filling and draining processes. When it malfunctions, it can disrupt the dishwasher’s operation, leading to the error code.

2. Float or Float Switch Issue:

Another possible cause of the E05 error is a damaged float or a defective float switch. The float is a small device located at the base of the dishwasher, and it rises with the water level during a cycle. The float switch is responsible for signaling when the appropriate water level is reached. If either of these components is not functioning correctly, it can trigger the error code.

Troubleshooting the E05 Error Code:

Before scheduling a service call with a Bosch technician, there are some steps you can take to troubleshoot and potentially resolve the E05 error:

1. Inspect the Float and Float Switch:

Start by checking the float and float switch. Ensure they are clean and free from any debris or blockages that might hinder their movement.

2. Reset the Dishwasher:

Sometimes, a simple reset can clear error codes. Turn off the dishwasher’s power for a few minutes and then turn it back on.

3. Check for Leaks:

Inspect the area around your dishwasher for any signs of water leakage. Leaks can trigger the E05 error, so fixing any leaks could resolve the issue.

4. Contact a Technician:

If the error persists after these troubleshooting steps or if you’re unsure about diagnosing and fixing the problem yourself, it’s advisable to contact a Bosch technician. They have the expertise and tools to diagnose and repair the water switch Triac or replace any faulty components.

In summary, the Bosch Dishwasher Error Code E05 can be attributed to a water switch Triac fault on the main control board or issues with the float and float switch. By understanding the potential causes and taking appropriate troubleshooting steps, you can address the problem effectively. If the error lingers, don’t hesitate to reach out to a Bosch technician for professional assistance. A functioning dishwasher is essential for a smooth-running kitchen, and resolving error codes promptly ensures your dishwasher operates at its best.
