What are error codes, and why are they essential for your Bosch dishwasher? If you have never heard of an error code, that’s okay. Most of the time, error codes are pretty rare, and you will only see one if there is a problem with your dishwasher.

In this guide, we will discuss what error codes are and explain what they mean. Bosch dishwashers have several error codes, so it’s important to know which ones to look out for.

This guide refers to the following model numbers:
















What is a dishwasher error code?

Many appliances, such as Bosch dishwashers, provide error codes. Each error code is specific to a dishwasher malfunction. So, you can fix your dishwasher just by finding out what the error code means.

For example, the error code E22 tells you that the dishwasher’s filter is blocked. Once you fix the problem with the filter, the error code will disappear.

Therefore, these error codes have quite a useful purpose. While they may seem annoying initially, they are actually here to help.

Many people find the codes difficult to interpret because they have random numbers and letters. With the Bosch dishwasher codes, the E stands for error, and the number is a reference for the problem. Hence, the number will direct you to what the problem is.

Although there are other Bosch dishwasher error codes that have an F instead of an E. Additionally, the water tap symbol that flashes on the screen also counts as an error code.

Sometimes these codes disappear for no apparent reason; if that’s the case, you probably don’t need to worry. But when the error code keeps returning or remains, you need to find out what it means.

Ignoring the error code could make the problem worse. Further damage could result, making the repairs more expensive as they will be harder to fix. It’s also important to note that some error codes are in place to prevent potential hazards, such as flooding.

Where can you find out what error codes mean?

Like most manufacturers, Bosch will update their error codes from time to time. For instance, newer models may have a slightly different list of error codes. Therefore, keeping your appliance manual is essential because it will list all of the error codes that apply directly to your dishwasher. But if you get stuck, you can refer to their website. 

Common Bosch dishwasher error codes

According to the Bosch website, these are the latest error codes they have listed.

If your dishwasher displays any of the following error codes, these are the likely problems:

  • E12 / F12: there is a build-up of limescale in the dishwasher (descale dishwasher before next use)
  • E14 / F14: check the water inflow (the inlet hose could be kinked)
  • E15 / F15: the water protection system has been activated to prevent flooding
  • E16: check the water inflow (the inlet hose could be kinked)
  • E17: check the water inflow (the inlet hose could be kinked)
  • E18: check supply hose and filter
  • E19 / F19: there is a problem with the dishwasher’s internal valve
  • E22: Filter is blocked and must be cleaned
  • E23: check the wastewater pump
  • E24 / F24: the water pump is blocked
  • E25: the pump is blocked or not attached correctly
  • Water tap symbol displayed: problem with the hose or low water pressure or blocked filter

What to do if there is an error code

For most error codes, Bosch recommends the following steps:

  1. Turn off the dishwasher. 
  2. Switch off the water supply to the dishwasher if necessary. 
  3. If the problem is not related to general maintenance (descaling or unblocking filter), seek advice from Bosch or your dishwasher dealer (especially if your dishwasher is still under warranty). 
  4. Avoid using the dishwasher until the problem is resolved.

However, it would also be helpful to ensure there is no water pooling in the bottom of the dishwasher. To resolve this, you may need to tilt the dishwasher at a 45-degree angle. Doing so will help the water to drain when the dishwasher is switched off. Afterward, allow it to dry for one day.

Can you override an error code on a Bosch dishwasher?

Sometimes, you can make the error code disappear by switching off the dishwasher and turning it back on. But it’s highly unlikely that the error code will disappear for good, especially if the problem is serious.

However, even if it were possible, overriding the error code is not recommended. The error codes are warning signs and signify that the dishwasher needs repairing. Therefore, they have an important purpose, and if you see an error code, you should try to fix the problem rather than ignore it.

Can you still use a Bosch dishwasher when the error code is present?

Depending on the type of error code, you might be able to use the dishwasher. But again, Bosch does not recommend using the dishwasher until the problem is resolved, as this could cause further damage to your appliance.

Additionally, you may find that the dishwasher is functioning less optimally when the error code is present. For example, you may notice watermarks on your glassware or residue on your plates and cups. The dishes and dishwasher may also start to smell, or a bad odor could linger in your kitchen.
