Bosch Dishwasher Error code E17 & E18

Bosch dishwashers are known for their efficiency and reliability, but like any appliance, they can encounter issues from time to time. Two common error codes that users may come across are E17 and E18, both of which indicate problems related to water supply. In this article, we’ll take a closer look at these error codes, understand what they mean, and provide detailed solutions for resolving them.

E17 Error Code: The Dishwasher Is Not Filling With Water

When your Bosch dishwasher displays an E17 error code, it’s signaling that it’s not receiving an adequate supply of water. Here’s how you can address this issue:

  1. Check the Water Supply Line:

    • Start by inspecting the water supply line. Ensure that it is correctly connected to the dishwasher and that the shut-off valve is turned on.
    • Look for any kinks or bends in the water supply hose. A kinked hose can restrict water flow to the dishwasher. If you find any kinks, straighten the hose to allow for proper water flow.

  2. Inspect the Water Inlet Valve:

    • If the water supply line is in good condition and properly connected, but the E17 error persists, the problem may lie with the water inlet valve.
    • The water inlet valve is responsible for allowing water to flow into the dishwasher. If it’s faulty or clogged, it can impede water flow. It’s recommended to replace the water inlet valve if necessary.

E18 Error Code: Insufficient Water Flow

The E18 error code is closely related to the E17 code and also indicates an issue with water supply. Here’s how to address this error:

  1. Check the Filter:

    • Insufficient water flow can sometimes be due to a clogged filter. The dishwasher’s filter can accumulate debris over time, restricting water flow.
    • Locate and remove the dishwasher’s filter. Clean it thoroughly, removing any debris or food particles. Ensure it’s properly reinstalled.

  2. Inspect the Water Supply Line and Valve:

    • As with the E17 error, check the water supply line and the shut-off valve. Ensure they are functioning correctly and not obstructed.

  3. Verify Water Pressure:

    • Low water pressure can also lead to an E18 error. Check your home’s water pressure to ensure it meets the dishwasher’s requirements.

By following these steps and addressing the specific issue related to the E17 and E18 error codes, you can often resolve the problem without the need for professional assistance. However, if you encounter persistent issues or are unsure about the diagnosis and repair, it’s advisable to seek the help of a qualified technician.
