What Does Error Code E15 Mean on Bosch Dishwasher?
The Bosch Dishwasher E15 error code indicates that the appliance’s safety system has detected water in the base of the dishwasher. This safety feature is designed to prevent further damage by stopping the dishwasher from running when a leak is detected. The error usually points to a problem within the dishwasher, such as a faulty door seal, a blocked drain, or issues with the water supply hose.
When the E15 error code appears, the dishwasher’s internal system triggers a float switch. This switch activates when excess water collects at the bottom, signaling a leak or an overflow. The system then automatically shuts down to avoid any further complications.
What Are the Causes of E15 Error on Bosch Dishwasher?
Here are the top causes of Error code E15 on the Bosch dishwasher:
Water Leaks
The most frequent cause of the E15 error on a Bosch dishwasher is water leaking into the base of the appliance. Leaks can occur due to several reasons, including a faulty door seal, which allows water to escape during a wash cycle. Additionally, issues with the inlet valve, which is responsible for regulating the flow of water into the dishwasher, can also result in leaks. Hoses connected to the dishwasher, if damaged or improperly installed, may lead to leaks as well, causing water to accumulate at the base and triggering the safety switch.

Obstructions or kinks in the water inlet hose can restrict the flow of water into the dishwasher, leading to the E15 error. Over time, debris can build up in the hose, reducing its efficiency and causing the appliance to malfunction. Incorrect installation of the hose can also create bends or kinks that impede water flow, resulting in the dishwasher’s safety system detecting a problem and activating the error code.
Malfunctioning Aqua-Stop Safety Device
The Aqua-Stop safety device is an essential component designed to detect leaks and shut off the water supply to prevent flooding. If this device malfunctions, it may falsely detect a leak and activate the E15 error code. Even when there is no actual water leak, a faulty Aqua-Stop can still trigger the dishwasher’s safety mechanism, causing unnecessary disruptions in its operation.
Control Board Glitch
Occasionally, the E15 error can be attributed to a glitch in the dishwasher’s control board. The control board manages various functions within the appliance, and a temporary glitch can cause the safety system to trigger the E15 error code. In such cases, performing a hard reset by disconnecting the power to the dishwasher for five minutes might clear the error and restore normal function.
Over-Sudsing
Using too much detergent or an unsuitable type can result in excessive suds forming during the wash cycle. This over-sudsing can cause water to overflow into the base of the dishwasher, leading to the activation of the safety switch and the E15 error. Ensuring that the correct amount and type of detergent is used can prevent this issue and keep the appliance running smoothly.
