How to Fix Bosch Dishwasher Error Code E04

Bosch dishwashers show the E04 error code on a display when there’s an issue with the water flow sensor.

If your Bosch dishwasher is showing this error, you should first check to make sure that it isn’t clogged or not getting enough water from your home gauge.

A Bosch dishwasher can also show the E04 error if one of its injectors has failed due to high levels of hard water (due to calcium build-up) and corrosion.

The injectors frequently get clogged or break due to high water hardness, which results in the sprinkler breaking. As a result, the sprinkler is unable to function well, and you are highly likely to experience water entering slowly.

How to Clean Sprinklers

If the Bosch Dishwasher Error Code E04 reappears, you need to clean the sprinkler: 

  • Remove the Sprinkler
  • Rinse it under running water. 
  • Brush nozzles with a toothpick or other objects in order to remove all dirt from holes. 

If you have hard water, purchasing an acid cleaner from your local hardware store will help remove calcium build-up to clog the jets in your Bosch dishwasher’s sprinkler. 

You should also try using vinegar for cleaning purposes as it is one of the most popular methods used today. It helps break down limescale deposits and soap scum on dishes while also killing odor-causing bacteria; however, make sure not to pour anything acidic into your Bosch dishwasher as this could damage its internal components. 

NOTE: Dishwashers function better and last longer with soft water. The best way to achieve this is by using water softeners, which prevent calcium and lime deposits from forming on the dishwasher’s internal parts, ensuring that they stay smooth and can spin freely.

What To do When Cleaning Does not remove the E04 Error?

The water flow sensor is a device that notifies the control module on when to stop or start pumping. 

When it has stopped working, it will trigger an error code and turn off power in order to protect your Bosch dishwasher from being damaged by flooding. 

If you’ve tried everything else but are still seeing Bosch Dishwasher Error Code E04, this may be what needs replacing.
