Bosch is one of the best dishwasher brands, appreciated for its impressive features and advanced technology. However, like with all home appliances, it’s not uncommon to encounter a few snags along the way. One of the most common issues encountered with Bosch dishwashers is the E24 error code, but what does it mean?
The E24 error can initially seem like a perplexing problem. However, once you understand what it means, you’re halfway to resolving it.
This error message is Bosch’s unique code for indicating that there’s an issue with your dishwasher’s drainage system. Essentially, it’s a distress signal from your appliance, akin to saying, “Houston, we have a drainage problem.”
When you see this error, it typically suggests that your dishwasher isn’t draining properly. This could be due to a variety of reasons. Most commonly, it’s because the drain filter is blocked. A clogged filter can prevent water from exiting the dishwasher, causing the machine to flash the E24 error code.
Step 1: Reset the Dishwasher
Resetting your dishwasher is as easy as pie and can often be the quick fix you need when it’s acting a bit off.
Here’s how to do it: First, locate the plug for your dishwasher. It’ll typically be under your sink or behind the dishwasher itself.
Next, give that plug a gentle tug to unplug it. Now, here’s the crucial part—you need to leave it unplugged for about 30 seconds. This brief pause gives your dishwasher a moment to reset its systems.
Once you’ve patiently waited those 30 seconds, it’s time to plug it back in. And voila! You’ve successfully reset your dishwasher.
Step 2: Clean the Dishwasher Filter
The filter collects food debris and dirt during the washing cycle. Over time, if not cleaned regularly, this debris can cause a blockage that leads to the E24 error code.
To fix this issue, remove the dishwasher filter and clean it. Use a soft dish brush or toothbrush to clear away any debris or dirt. Rinse the filter under hot water to ensure it’s completely free of debris. Once done, put the filter back in place and run a test cycle to see if the error has been resolved.
Step 3: Check the Drain Hose
The first step in fixing the E24 error code is to check the drain hose. To do this, turn off the dishwasher and unplug it. Be sure to turn off the water, too.
Check the dishwasher drain hose for any visible damage, such as cracks or kinks. If there’s any damage, you’ll need to replace the hose.
If there is no visible damage, put down some towels, detach the drain hose from the dishwasher and the sink, and look through the hose. If you can’t see through the hose to the other side, it’s most likely clogged.
Proceed to the next step.
Step 4: Unclog the Drain Hose
To unclog the drain hose, remove any visible debris and clean the hose with a high-pressure hose. Your garden hose can also work.
Alternatively, use a plumbing snake to unclog the drain hose. Insert the snake into the clogged end and push it through until it comes out the other end. This will clear any blockages in the drain hose.
Once the hose is clear, reattach it to the dishwasher and sink, ensuring it’s securely connected.
Turn the water back on and run a test cycle.
Step 5: Check the Garbage Disposal
If the E24 error code persists, check the garbage disposal. The drain and garbage disposal are often linked in most kitchens.
Turn off the dishwasher and garbage disposal, unplug them, and check for any obstructions or clogs. Remove any debris or foreign objects (like forks) that may be blocking the disposal.
Make sure it’s not clogged and that the blades are functioning correctly. If the garbage disposal is malfunctioning, you’ll need to call a professional plumber to fix it.
Step 6: Check the Drain Pump
Let’s delve a little deeper into the essentials of maintaining your drain pump. This crucial component is responsible for ensuring that water exits your appliance after each wash or rinse cycle. However, like any other part, it can become clogged with food particles or debris, disrupting its smooth operation.
Start by thoroughly inspecting your drain pump.
To access the drain pump, unplug the dishwasher and turn off the water. Using a screwdriver, remove the kickplate at the base of the dishwasher. You will find the drain pump by following the drain hose. With a towel and a pair of pliers, remove the clamps holding the hoses in place. Inspect the drain pump.
Look out for any potential obstructions—these could be anything from small food particles to tiny objects that have accidentally slipped in.
If you do discover any blockages, gently clean them out using a soft brush or cloth. If the debris is particularly stubborn, then warm, soapy water might come in handy. Just remember to dry everything before putting it back together.
Next, check if your pump is working efficiently. Manually spin the mechanisms and test continuity with a multimeter. If the pump does not spin or there is no continuity, the pump will need to be replaced.
You can either tackle this task yourself if you’re comfortable doing so or enlist the help of a professional to ensure it’s done correctly.
To replace the drain pump, simply connect the new one the same way the old one was connected.
If all is clear and working properly, return the drain pump and reinstall the kick plate. Then plug the dishwasher back in and turn on the water. Test your appliance to ensure that the pump is now functioning properly.
Step 7: Call a Professional
If you’ve tried all these steps and the E24 error code still appears, it’s best to call a professional Bosch dishwasher repair service. They’ll be able to diagnose the problem and fix it quickly.
A Bosch dishwasher that doesn’t drain can be frustrating, but with a few little steps, you’ll most likely be able to fix it yourself. Start by checking the drain hose and unclogging it if necessary. Clean the dishwasher filter and check the garbage disposal. If all else fails, call a professional. With these tips, you’ll have your Bosch dishwasher up and running in no time.
