Understanding the E09 Error Code

The E09 error code in Bosch dishwashers typically indicates a problem with the appliance’s water supply. It can be caused by various factors, including:

• Clogged water inlet valve
• Faulty water pressure switch
• Damaged water hose
• Low water pressure

Troubleshooting the E09 Error Code

Before jumping into repairs, it’s essential to troubleshoot the issue to pinpoint the exact cause. Here are some steps to follow:

1. Check the Water Supply

Ensure that the water supply to your dishwasher is turned on and that there are no kinks or leaks in the water hose.

2. Clean the Water Inlet Valve

• Use a multimeter to check for continuity between the two terminals on the switch.
