Bosch Dishwasher is displaying an error code E12, what does it mean?
Error code E12 on a Bosch dishwasher indicates a problem with the heating element. This could be caused by a number of factors, such as a faulty heating element, a problem with the thermostat, or a problem with the wiring.
Here are some steps you can take to fix the error code E12 on your Bosch dishwasher:
- descale dishwasher: An E12 error code indicates a build-up of limescale in the heat pump. Please purchase the Bosch descaler to remove hard water deposits and limescale buildup.
- Check the heating element: The heating element is responsible for heating the water in the dishwasher. If the heating element is faulty, it may not be able to heat the water to a high enough temperature, which can prevent the dishwasher from cleaning dishes properly. To check the heating element, you will need to use a multimeter to test its resistance. If the resistance is outside of the normal range, the heating element will need to be replaced.
- Check the thermostat: The thermostat is responsible for regulating the temperature of the water in the dishwasher. If the thermostat is faulty, it may not be able to maintain the water at a consistent temperature, which can prevent the dishwasher from cleaning dishes properly. To check the thermostat, you will need to use a multimeter to test its resistance. If the resistance is outside of the normal range, the thermostat will need to be replaced.
- Check the wiring: The wiring that connects the heating element and the thermostat may be damaged, which can prevent the dishwasher from heating the water properly. To check the wiring, you will need to use a multimeter to test its continuity. If the wiring is damaged, it will need to be repaired or replaced.
If you have checked all of the above and you are still getting error code E12, you may need to contact a Bosch technician for further assistance.
Here are some additional tips for troubleshooting error code E12 on a Bosch dishwasher:
- If the error code appears immediately after turning on the dishwasher, it may be a problem with the power supply. Try unplugging the dishwasher for a few minutes and then plugging it back in.
- If the error code appears while the dishwasher is running, it may be a problem with the dishwasher itself. Try turning off the dishwasher and unplugging it from the power outlet for a few minutes. Then, plug it back in and restart the dishwasher. If the error code persists, contact Bosch customer support.
