If the water does not reach the appropriate temperature, the dishwasher will not be able to properly dissolve the detergent or remove all the dirt and grease accumulated on the dishes. To find a solution to this problem, you first need to understand the causes that could lead to it:

• The thermostat and/or temperature sensor are faulty or miscalibrated: If these components are not functioning properly, the dishwasher will not measure the water temperature correctly, causing it not to heat up when it should.
• The heating element that warms the water is damaged or dirty: This is the heating element responsible for heating all the water in the dishwasher. A faulty heating element is undoubtedly a major problem for the proper functioning of a dishwasher.
• Issues with internal wiring: The electrical circuit that connects the thermostat and the heating element is broken or loose, and does not transmit the appropriate current. Similarly, corroded connections due to excess moisture could also cause the dishwasher not to function properly.
• The control panel is damaged: A defective electronic control board will not be able to properly regulate water heating, as this component controls absolutely all the functions of your Siemens dishwasher.

All these are the causes that lead to this fault in your dishwasher, but you don’t have much to worry about, because we could solve it today.

How can the error E9 fault in your Siemens dishwasher be fixed?

If you are desperate to address this situation as soon as possible, then we have the answer and solution for you. Follow these steps to the letter and do not skip any, and you will surely be able to fix this issue:

1. Restart the dishwasher to perform a general reset of the sensors: A complete restart of the dishwasher can help solve this problem as the sensors may return to normal. To do this, disconnect the dishwasher's power cord from the electrical outlet. Now, let the dishwasher rest for about 15 minutes to allow the capacitors to release all that accumulated energy and for the internal memory to be cleared. When the time has passed, reconnect the power cord to the outlet and make sure the connection is firm and secure. Turn on your Siemens dishwasher and wait for it to fully start. Select a short wash program and check if the fault has disappeared.
2. Check the thermostat, heating element, and temperature sensor of your Siemens dishwasher: You will need to remove the bottom panel of the dishwasher and locate these components. Check if they are dirty, rusty, damaged, or corroded and clean them or replace them if necessary. If you have knowledge of electronics, it would be ideal to check these components with a multimeter to ensure they are functioning properly. These components must be in very good condition for your dishwasher to operate properly, especially the heating element, which is the critical component that heats the water. Once you have checked these three components, verify that the dishwasher is working correctly and can heat the water normally.
3. Inspect the internal wiring of your Siemens dishwasher: Make sure all the wires in your dishwasher are in good condition. You will need to check them one by one and also check the connections to ensure they are not corroded. If you find broken, disconnected, corroded, or burnt wires, you will need to make the necessary repairs to resolve this issue. The wiring allows communication between all the components of your dishwasher, so it needs to be in perfect condition, or otherwise, the appliance will not function as it should. Once you have completed the repairs, check everything with a multimeter to ensure proper operation.
4. Check the control panel or electronic board of your Siemens dishwasher: You need to remove the front panel of the dishwasher and check if any component on the electronic board is burnt or damaged. Use a multimeter to detect faults that are not visible to the naked eye. Also, check for swollen, burnt, or corroded components. If so, you will probably need to replace the PCB electronic board with a new one that is compatible with your dishwasher model. It would not hurt to perform maintenance on this board with a good electronic cleaner and, as a last resort, use an ultrasonic cleaner and/or apply heat to return the solder to its place.
5. Repeat all the previous steps if the problem persists in the dishwasher: Perform a second check of everything we have indicated earlier. You need to follow all the steps exactly as we have indicated, paying attention to the small details. Once you have checked everything again, see if the problem persists in your dishwasher. If after performing all the necessary checks and repairs, the fault still appears, then there is a possibility that the issue is more complex than it seems and may require professional intervention.
6. Contact Siemens technical support to resolve the issue: If you cannot solve this issue on your own or prefer to leave the problem to the experts, you can contact Siemens official technical support and request a home visit. They will be responsible for diagnosing and repairing your dishwasher with all the available guarantees. Additionally, Siemens has all the technical knowledge necessary to repair your dishwasher since they designed it themselves.
