E:12 · Heating element blocked by limescale

Safe first steps

1. Turn off the dishwasher and unplug it from the power source.
2. Check the water supply valve and ensure it is fully open to prevent any water flow issues.
3. Prepare a descaling solution according to the manufacturer's instructions and pour it into the dishwasher's detergent compartment.
4. Run a short wash cycle without dishes to allow the descaling solution to work on the heating element.
5. After the cycle, check for any remaining limescale and repeat the descaling process if necessary.

When to stop

• If the error persists after descaling, or if you notice any unusual noises or leaks, stop and call a professional.
