If you’re uncomfortable performing the replacement yourself, contact a professional for assistance from Smart Appliance Services. 

Causes of Bosch Dishwasher E09 Error

Several factors can cause the E09 error code to appear on your Bosch dishwasher. While a faulty heating element is the most common culprit, other components like water leaks, clogged filters, and defective thermostats can also contribute to this issue.

Heating element failure

The most common cause of the Bosch dishwasher E09 error code is a faulty heating element. The heating element may become damaged, burnt out, or corroded over time, preventing it from properly heating the water. When the heating element fails, the dishwasher won’t be able to clean dishes effectively, and the E09 error code is triggered.

Water leaks and wiring issues

Water leaks, especially near the heating element, can cause shorts in the wiring. This can interfere with the heating element’s functionality and lead to the Bosch dishwasher error code E09. Additionally, wiring issues can occur between the components like the heating element and the main PCB, which can also trigger this fault.

Hard water and scale build-up

Hard water can lead to mineral deposits and scale buildup on the heating element. Over time, this scale buildup can cause the heating element to overheat and eventually fail. Regular cleaning and using a water softener can help prevent Bosch dishwasher E09 fault from recurring.

How to Fix Bosch Dishwasher E09 Error

If you’re encountering the Bosch dishwasher E09 fault, follow these steps to troubleshoot the problem and resolve it. If you’re unsure how to fix this issue, you can always reach out to a professional for Bosch Dishwasher Repair to ensure the problem is properly addressed.

Testing the heating element

First, inspect the heating element for visible damage. If the element appears damaged, it may need to be replaced. You can also use a multimeter to test the heating element for continuity. Set the multimeter to resistance (ohms) mode and check the element’s resistance. If the reading is too high or shows no continuity, the element is faulty and will need replacement.

Inspecting the thermostat and wiring

Next, check the thermostat to ensure it’s working properly. A faulty thermostat may fail to regulate the temperature properly, contributing to the error. Additionally, inspect the wiring connections between the heating element, thermostat, and the main PCB. Loose or damaged wires can cause shorts, triggering the Bosch dishwasher error code e09. Ensure all connections are secure and intact.

Replacing the heating element

If the heating element fails the resistance test or shows signs of physical damage, it will need to be replaced. Replacing the heating element requires disassembling part of the dishwasher, so it’s important to follow proper safety procedures.
