How To Fix Bosch Dishwasher E17 Error Code

If your Bosch dishwasher displays an E17 error code, it’s usually related to a high water level in the machine.

If you’re seeing Bosch dishwasher error code E17, it’s most likely due to water overflowing inside the machine. To fix it, make sure that you close your Bosch dishwasher door properly and check the water level.

When water exceeds the sump level in your machine, a float valve rises, triggering a pump to expel excess water. If your dishwasher has begun overflowing with water, follow these steps:

  • Check that the pipe leading from the sump is clear of any obstruction.
  • Clean all the parts of the sump and float chamber.
  • If the problem persists even after you’ve made those adjustments, then chances are your float switch is faulty. In this case, you’ll need to replace it with a new one — also remember to check whether the wiring is securely attached to ensure that it doesn’t cause the problem either.
