Siemens Dishwasher Error 24

What does this fault affecting your Siemens dishwasher mean?

When you have a Siemens dishwasher, you need to know that you now have a very high-quality product. However, these appliances are not exempt from faults, as with any device, they can present malfunctions, especially if they have not had the proper maintenance.

The fault indicated by error code 24 in Siemens dishwashers means there is a problem with water circulation. This fault prevents water from circulating freely throughout your dishwasher's system, making it extremely difficult for the appliance to complete the washing cycles for your dishes. If you want to continue using your appliance safely, you will need to address this fault as soon as possible.

Among the possible causes that can lead to this type of error in your Siemens dishwasher, we have the following:

• A dirty and clogged filter: This part of the dishwasher catches all the solid dirt that may be contained on the dishes you are cleaning, such as bones left on plates. If this filter is very dirty, it can cause a clog in the entire drainage system of your dishwasher.
• A broken and damaged filter: Filters can break due to an excess of sharp bones in meals, such as fish and/or chicken bones. If the protective mesh of these filters is in poor condition, it can allow solids to pass directly into the dishwasher's drainage system and clog the entire water circuit.
• A valve that is not functioning correctly: The valves that control the inlet and outlet of water may be damaged or very dirty and clogged, making it difficult for water to flow freely through the water circuit of your dishwasher.
• The water circulation pump is dirty or defective: This device is responsible for pushing all the dirty water through the drainage system to expel it from the dishwasher. If this pump is very dirty or damaged, this fault (as well as many others) will appear in your dishwasher.
• A crushed, broken, or poorly installed pipe: If the pipe is poorly installed, bent, or crushed by the dishwasher itself or by the wall, dirty water will not flow freely through the drainage system, causing the water circuit to collapse.

Now that you know all the causes that lead to this fault in Siemens dishwashers, it's time to see what solutions we can apply to fix it.

How could the fault 24 in the Siemens dishwasher be fixed?

We are going to provide you with a quite effective list of solutions to fix the error 24 in Siemens dishwashers. Follow the steps exactly and do not skip any so that you can continue using your dishwasher as usual:

1. Restart the dishwasher to perform a general reset of the sensors: A complete reset of the dishwasher can help reprogram these sensors and return them to their normal state. To do this, locate the dishwasher’s power cable and disconnect it from the power outlet. It is important to ensure that the dishwasher is completely disconnected from the electrical network to avoid safety risks. Once disconnected, let the dishwasher rest for at least 10 to 15 minutes. This time will allow the internal capacitors to discharge and the memory to reset completely. After the waiting time, reconnect the power cable to the power outlet and ensure that the connection is firm and secure. Press the dishwasher's power button to turn it on and wait a few seconds for the dishwasher to fully start up. Now select a short wash program and check if the error has disappeared.
2. Check and clean the drain filter of your Siemens dishwasher: The dishwasher drain filter is usually located at the bottom of the appliance, near the drain. Refer to your dishwasher's user manual for specific instructions on its location. Hold the filter by the handles and pull it up to remove it from its housing. Be careful not to spill any dirty water that the filter may contain. Remove food scraps and other debris that have accumulated in the filter. You can use a soft-bristle brush or a damp cloth to clean the filter. Rinse the filter with warm water to remove any remaining residue, you can use soap and some vinegar to disinfect it. Reinstall the drain filter and ensure that it is properly seated.
3. Perform preventive maintenance on the valves of your Siemens dishwasher: The dishwasher valves are usually located near the water inlet and outlet of the appliance. Refer to your dishwasher's user manual for specific instructions on their location. Before starting work on the valves, it is important to turn off the main water supply to the dishwasher. This will prevent water from flowing into the appliance while you perform maintenance. Disconnect the water hoses from the valves and be careful not to spill any liquid. Use a soft-bristle brush and warm water to clean the valves. Pay special attention to the water inlet and outlet holes, as they are prone to clogging. The valve seals are responsible for creating a watertight seal to prevent water leaks. If the seals are worn or damaged, you will need to replace them with new ones. Once you have cleaned the valves and checked the seals, reconnect the water hoses. Make sure the connections are tight and there are no water leaks.
4. Check and clean the water circulation pump of the dishwasher: The drain pump is usually located at the bottom of the dishwasher, near the drain filter. Remove the panels or covers that allow you to access the drain pump and be careful not to damage any components during this process. Disconnect the water hoses that enter and exit the drain pump. Hold the drain pump by the handles or designated grip points and pull it out to remove it from its housing. Carefully clean the drain pump, removing any food debris, dirt, or anything that could obstruct it. You can use a soft-bristle brush or a damp cloth to clean the pump. Pay special attention to the pump impeller, as it is the component that rotates to push the water. The pump seals are responsible for creating a watertight seal to prevent water leaks. If the seals are worn or damaged, you will need to replace them with new ones. After cleaning, place the drain pump back in its housing and ensure it is properly seated. Connect the water hoses to the drain pump and make sure the connections are tight. Now check if the fault has disappeared by starting a short wash cycle.
5. Check the drain hose for clogs: Inspect the drain hose carefully, looking for any signs of physical damage such as breaks, sharp bends, or water leaks. If you detect any damage, it is necessary to replace the hose with a new one to avoid bigger problems. Disconnect the drain hose from both ends and if you observe any obstructions, such as food debris or dirt, remove it carefully. You can use a thin wire or a flexible brush to get rid of the accumulated dirt inside this hose. Reconnect the drain hose at both ends and ensure the connections are tight to prevent water leaks. Run a wash cycle to check if the drainage problem has been resolved and if the hose is working correctly.
