Bosch Dishwasher Error Code E04

Bosch dishwasher error code E04 is the most common problem for Bosch models. If your machine displays “Dishwasher Error Code E04” on the display screen, don’t worry because we have a solution!

Error Cause

You will get this particular message when there’s water flow sensor failure in the unit, which enables it to stop from running due to its lack of operation as well being interrupting hot air circulation within cabinet spaces, causing drying out food items or even bacteria growths inside cabinets leading into poor hygiene standards among other problems like corrosion at hinges, etc.

Reasons

The E04 Error indicates that the dishwasher is not operating correctly because of a blockage or high water hardness.

A sprinkler system with numerous holes in it is likely to have a problem, because Jets that do not pass well through gaps in the sprinkler cause appliance failures.

If the damage is minor, you might fix it yourself. If you apply your own remedies for more than two hours without success, we recommend consulting a Bosch repair shop.

Fix Bosch Dishwasher Error Code E04

When the water flow sensor on a Bosch dishwasher fails, the machine displays the E04 error code.

If your Bosch dishwasher displays this message, check whether it is clogged or not receiving enough water from your home gauge.

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

Because of the high water hardness, injectors frequently become clogged or fail, preventing the sprinkler from working. Consequently, the sprinkler will not operate effectively, and you are likely to have water enter slowly.

Reset Bosch Error Code E04

To fix the E04 error code, unplug your Bosch dishwasher from the mains and wait 10-15 minutes before trying to start it again. If the symbols go away, everything is fine.

If they return, you must take action. You can contact the Bosch service center for further assistance if this happens again.

Clean Sprinklers

If the Bosch Dishwasher Error Code E04 appears again, you must clean the sprinkler:

  • Remove the Sprinkler
  • Rinse it under running water.
  • Remove all dirt from holes using a toothpick or other tools.

If you have hard water, a mild acid from your local hardware store can help clear calcium build-up from the nozzles in your Bosch dishwasher’s sprinkler.

Another favorite way to clean it is with vinegar, one of the most popular cleaning techniques today.

It aids in the breakdown of limescale deposits and soap scum on dishes and inhibiting odor-causing germs; nevertheless, avoid pouring acidic substances into your Bosch dishwasher since this can damage its internal components.

NOTE:¬†Soft water is necessary for efficient and long-lasting dishwashers. The easiest way to get this is with a water softener, which prevents calcium and lime deposits from forming on the dishwasher’s internal components, ensuring that they remain smooth and spin freely.

What Should You Do If Your Cleaning Didn’t Remove the E04 Error?

According to the control module, water flow sensors indicate when to cease or begin pumping.

If the pump fails, it will set off an error code and turn off electricity to prevent your Bosch dishwasher from being damaged by water.

If you’ve tried everything else and are still getting the Bosch Dishwasher Error Code E04, this is where the part should be changed.

When selecting a new dishwasher part, the most essential things to consider are brand and model. Original spare parts will almost consistently outperform generic replacements since they were designed specifically for your device.

Avoid Error Code E04 In Future

Regular cleaning is one of the most effective methods to keep your dishwasher in good working order. When it’s time for a hand, you’ll notice streaks on the dishes or water remaining in the sink basin.

Make careful to remove all trapped food – insert your hand into the machine and wiggle around the blades and joints. Cleaning the filters and other components at least once a month is also a good idea.
