Bosch Dishwasher Error Code E17 — How to Fix (Overfill)

If you’re seeing the Bosch Dishwasher error code E17, it means your appliance has detected excessive water in the tub. This error can cause your dishwasher to malfunction or even leak, so it’s essential to address the issue promptly. In this comprehensive guide, we’ll walk you through the possible causes, diagnostic steps, and repair procedures to fix the E17 error code.

What Bosch Dishwasher Error E17 Actually Means

The E17 error code on your Bosch Dishwasher indicates that the appliance has detected a high water level in the tub. This error is usually triggered by a faulty water level sensor or float switch assembly. The water level sensor monitors the water level in the tub and sends signals to the control board to regulate the water intake. If the sensor detects an excessive water level, it sends an error signal to the control board, which displays the E17 error code.

The sensor or component that triggered the E17 error code is likely the water level sensor or float switch assembly. It’s essential to investigate and address the issue to prevent further damage to your dishwasher.

As for safety, it’s not recommended to continue using your dishwasher with the E17 error code. Excessive water in the tub can cause leaks, flooding, or even electrical shock. Therefore, it’s crucial to diagnose and fix the issue as soon as possible.

Quick Diagnostic Checklist (use before calling anyone)

Before calling a professional or spending money on repairs, perform these quick diagnostic checks:

• Check the dishwasher’s drain: Ensure the drain hose is not kinked or clogged, which can cause water to accumulate in the tub.
• Inspect the water inlet valve: Verify that the water inlet valve is not stuck or faulty, causing excessive water intake.
• Power cycle the dishwasher: Unplug the dishwasher from the power outlet, wait for 30 seconds, and plug it back in. This simple reset can sometimes resolve the issue.
• Check for blockages: Verify that the dishwasher’s filters and drain are clear of debris and food particles.

For Bosch dishwashers, a specific power cycle procedure is to press and hold the “Start” button while unplugging the dishwasher. Wait for 30 seconds and plug it back in while still holding the “Start” button.
