It’s always stressful when you have an issue with your dishwasher—after all, no one likes to have to hand wash their dishes! If your Bosch dishwasher is showing an E24 error code, this usually signifies a problem with drainage. There are quite a few different causes for drainage issues in dishwashers, and luckily there are some easy DIY solutions you can try. 

This guide applies to all popular models of Bosch dishwashers, including:






















Try a hard reset

Sometimes an error code can be displayed mistakenly if your Bosch dishwasher experiences a power surge or a glitch. Resetting the dishwasher will clear any glitches, meaning the error code will go away and the dishwasher will work as normal. Here’s how to perform a hard reset on your Bosch dishwasher:

  • Disconnect your dishwasher from its power source. You can either turn it off or trip the circuit breaker
  • Leave the dishwasher disconnected from the power source for at least five minutes. This will allow the electrical components to discharge, allowing for a full reset. 
  • Reconnect your dishwasher to the power source. Turn it on and check if the error code is still on the display. If not, try running a cycle and see if it works as normal. If the error returns, try one of the other fixes in this guide.

Clean the filters

Dishwasher filters are in charge of stopping food debris from clogging the drainage system. Ideally, filters should be changed regularly, but if you neglect to do so, a clogged filter can prevent your dishwasher from fully draining. This can trigger the E24 error in your dishwasher. If you notice pooling water in the bottom of your Bosch dishwasher, as well as food debris gathering around the filter area, then cleaning the filter is probably the solution. 

To fix:

  • Access your dishwasher filter. You’ll need to take out the bottom dish rack, remove the filter cover then unscrew the filter. 
  • Rinse the filter thoroughly under running water until clean. If there is stubborn debris, use a soft brush to dislodge any remaining dirt. 
  • If the grime proves stubborn, try soaking the filter in warm, soapy water until the debris softens, then scrub it again. 
  • Rinse the filter thoroughly then put it back in place. 
  • Try running a cycle to see if the error code has cleared. If not, try one of the other solutions in our guide. 

Check the drain hose

The E24 error code refers to a drainage issue, and as such anything that interferes with drainage can be responsible. A blocked or kinked drain hose means that the dirty water from inside your dishwasher can’t drain properly, and water can pool in the bottom of the dishwasher’s interior. 

To fix this:

  • Turn off the power to your dishwasher either by unplugging it or cutting power to the circuit breaker. 
  • Access the drain hose. In most Bosch models, the drain hose is located at the back of the dishwasher, so you may need to pull your dishwasher away from the wall to gain access. 
  • Make sure you have old towels or a bucket on hand to catch any residual water that might be in the drain hose. 
  • Check the hose for any obvious kinks. If there are any sharp bends in the hose, straighten them out. 
  • If there are no obvious kinks, you’ll need to check the hose for clogs. Disconnect the hose from the back of the dishwasher and remove the other end from the drain pipe. 
  • Check the pipe for clogs. If you can’t see any, run water through the pipe to make sure water can run freely. 
  • Use a length of wire or a long, slender brush to clear out any clogs. Make sure water runs freely through the drain hose before you put it back into place. 
  • Once you’ve reinstalled the drain pump and put the dishwasher back in place, turn it on and run a test cycle to see if the error code has cleared.

Unclog the drain pump

A blocked drain pump can also lead to drainage issues, which can trigger the E24 error code. The drain pump expels dirty water from your dishwasher into the drain hose and your home’s drainage system. 

Other signs of a blocked drain pump include strange noises during the drainage part of the wash cycle, and pooled water in the bottom of your Bosch dishwasher after the cycle is finished. Please note, this step is a little more technical than the others, so if you’re not confident about taking apart your dishwasher yourself, you should contact a professional technician. 

To fix this:

  • Disconnect the dishwasher from the power.
  • Gain access to the drain pump. You can check your Bosch manual to find out its exact location in your model, but in many cases, you’ll need to remove the lower front panel. 
  • Once you have access to the pump, carefully check for any obstructions. 
  • Locate the pump’s impeller—it looks like a round, plastic cog or fan blade. This is the most common place for obstructions to occur. 
  • Check for blockages in the impeller, like broken glass or crockery. Clear any loose pieces out and check if the impeller can spin properly. 
  • Using a multimeter, check the pump for continuity. If it has no continuity, it will need to be replaced with a compatible part. You can source replacement parts online, or contact an appliance repair technician. 
  • Once the pump is either replaced or cleared of obstructions, run a test cycle to make sure the error code has cleared.
