E17 Error Code Bosch Dishwasher

The E17 error code on a Bosch dishwasher is an indication of a potential issue related to the volume regulator in the Aquastop band. The Aquastop is a safety feature that controls the water inflow into the dishwasher. The volume regulator within the Aquastop band helps limit the amount of water that enters the dishwasher during a cycle.

If you encounter the E17 error code, it is essential to address the issue promptly to ensure the dishwasher operates efficiently and safely.

Step-by-Step Guide to Fix the E17 Error:

Safety First:

Before you begin any repairs, ensure your safety by turning off the power supply to the dishwasher and shutting off the water supply valve.

Uninstall the Dishwasher:

To access the float switch for replacement, you’ll need to uninstall the dishwasher. Follow these steps:

• • Remove the screws to release the lower access panel and set it aside.
  • Disconnect the water supply line from the inlet valve (be prepared for some water spillage).
  • Remove the mounting screw to release the junction box cover.
  • Note the orientation of the wires on the terminal block, then loosen the screws to release the wires.
  • Remove the screw to detach the wire strain relief bracket.

Disconnect the Drain Hose:

Feed the drain hose through the cabinet by disconnecting it from the sink or garbage disposer.

Release the Float Switch:

Carefully remove the dishwasher’s mounting bracket screws and pull it away from the cabinet. Then, follow these steps:

• • Pull the hose manifold out of the air pressure chamber.
  • Pull the pressure chamber out of the base and disconnect the inlet hose.
  • Unhook the wires from the retaining clip and disconnect the wire harness.
  • Use a flathead screwdriver to pry the chamber cover off.
  • Carefully pull the locking tabs to release the old float switch.

Install the New Float Switch:

Now that you have the old float switch removed, let’s install the new one:

• • Snap the new float switch into place on the air pressure chamber.
  • Position the chamber cover and snap it into place.
  • Reconnect the wire harness to the pressure chamber and secure the wires in the retaining clip.
  • Reconnect the inlet hose and properly align the float switch activator as you insert the pressure chamber into the base.
  • Insert the hose manifold into the top of the pressure chamber, making sure the end of the drain hose is accessible through the cabinet wall.

Reinstall the Dishwasher:

Carefully slide the dishwasher back into the cabinet and adjust the leveling legs if necessary. Secure the dishwasher by replacing the locking screws and mounting brackets.

Reconnect the Drain Hose:

Feed the drain hose back through the cabinet and connect it to the sink drain or disposer. Ensure the hose is elevated above the connection point.

Secure the Wiring:

Insert the wire strain relief through the bracket and secure the nut. Align the bracket with the terminal block and replace the screw. Reattach the wires to their respective terminals and secure them without over-tightening.

Complete the Reassembly:

Replace the junction box cover and secure it with the mounting screw. Reconnect the water supply line to the inlet valve. Finally, replace the lower access panel and secure the screws.

Probable Sources of the E17 Error

• Volume Regulator in the Aquastop Band: The E17 error often points to a potential issue with the volume regulator in the Aquastop band. This component helps control water flow, and if it’s missing or defective, it can trigger the error.
• Flow Sensor Problem: Another possible source of the E17 error is a flow sensor issue in the heat exchanger. The flow sensor detects the water flow rate, and any disruption can lead to the error.

Identifying and Rectifying the E17 Error

• Uninstalling the Dishwasher: To begin troubleshooting, you’ll need to uninstall the dishwasher. Follow these steps:
  • Turn off the power supply and shut off the water supply valve.
  • Remove the screws to release the lower access panel and disconnect the water supply line from the inlet valve.
  • Release the junction box cover and note the orientation of the wires on the terminal block.
• Checking the Float Switch: The float switch is often responsible for triggering the E17 error. Here’s what you can do:
  • Remove the dishwasher’s mounting bracket screws and pull it away from the cabinet.
  • Locate the float switch, check for any signs of damage or misalignment, and replace it if necessary.
• Reassembling the Dishwasher: After installing the new float switch, carefully reassemble the dishwasher, ensuring all connections are secure.

Maintenance to Evade the E17 Error

• Regular Cleaning: Keep your dishwasher clean by regularly removing any debris or food particles from the filters, spray arms, and drainage system.
• Check the Inlet Hose: Ensure the inlet hose is not kinked or obstructed, as this can affect water flow and trigger error codes.
• Inspect the Aquastop Band: Periodically check the Aquastop band for any signs of wear or damage. Replace it promptly if needed.
• Flow Sensor Inspection: Take a look at the flow sensor in the heat exchanger and make sure it’s clean and functioning correctly.
