Fixing Bosch Dishwasher E17 Error [Step-by-Step Guide]

Experiencing the E17 error code on your Bosch dishwasher? This error usually means the water inflow system has a problem. It caused a higher-than-expected water level. Knowing the causes and the right fixes can quickly fix your dishwasher.

Understanding the Bosch Dishwasher E17 Error

The E17 error code on a Bosch dishwasher means there is a water level issue. The dishwasher detects that the water level is too high, or that water is entering it too quickly. This may be due to a problem with the filling system. It could also be a leak in the dishwasher’s door seal or internal parts. If left unaddressed, it could lead to excess water build-up at the base or even a leak onto the floor underneath.

Common Reasons for the E17 Error Code

Several factors could cause your Bosch dishwasher to display the E17 error code. The most common include:

• Water Pressure Issues: If the water pressure is too high, the dishwasher might detect an error as the water fills up too quickly.
• Clogged or Kinked Inlet Hoses: Any obstructions or damage in the hoses can prevent water from flowing properly.
• Malfunctioning Water Inlet Valve: This valve controls the flow of water into the dishwasher. If it’s faulty, it may not shut off when it should, causing a high water level.
• Faulty Flow Sensor: The flow sensor monitors how much water enters the dishwasher. A defective sensor can misread the amount of water, triggering the E17 error.

Steps to Troubleshoot the E17 Error Code

If your dishwasher shows the E17 error code, do this to fix it:

1. Check Water Supply: Ensure that the water supply is turned on and has adequate pressure. Low pressure might make the dishwasher overcompensate. This could raise the water level too high.
2. Inspect Inlet Hoses: Look for any kinks, blockages, or damage in the hoses. A clogged hose can restrict water flow. It can cause water to enter the sump or float chamber, raising the internal water level.
3. Test the Water Inlet Valve: To check the inlet valve, turn off the mains. Then, remove the valve and inspect it for obstructions or damage. If necessary, replace it to prevent excess water flow.
4. Check the Flow Sensor: It ensures the right amount of water enters the dishwasher. If it’s defective, the dishwasher might think there’s a high water level, even when there isn’t. Replacing the sensor could resolve the issue.

Solutions to Resolve the E17 Error Code

If the troubleshooting steps above don’t resolve the E17 error code, consider the following fixes:

• Adjusting Water Pressure: If the water pressure is too high, consult a plumber to adjust it to a level suitable for your dishwasher.
• Replacing the Water Inlet Valve: A faulty valve might not close properly, allowing too much water to enter. Replace it if it’s not functioning correctly.
• Clearing Blockages in Hoses or Filters: Over time, gunk can build up in the hoses and filters, causing water flow issues. Regular cleaning can prevent overfill and overflow problems.
• Replacing the Flow Sensor: If the flow sensor is malfunctioning, replace it to ensure the dishwasher correctly detects the amount of water entering.

When to Seek Professional Help for the E17 Error

If you’ve tried all the above steps and the E17 error code persists, it might be time to call in a professional. You need a pro if you see: ongoing leaks, a dishwasher overflow, or pooling water under the appliance.
