Error Code E:15

• Error Code: E:15
  • Appliance Type: dishwasher
  • Brands: Bosch, Siemens, Neff, Constructa, Gaggenau
  • Description: Description Error code E:15 indicates that the dishwasher’s water system (Aquastop) has been activated. This means there is water in the bottom of the machine due to a leak. The tap symbol may flash, and the “End” light will be on.

What you can do:

1. Remove the water from the bottom of the dishwasher.
2. Locate and repair the leak. On models with a stainless steel base, the leak is often located between the plastic base and the tub. A special repair kit with an additional seal is available for this.

Note when installing the repair kit:

• The seal must be guided through two narrow openings. Use a lubricant (e.g., rinse aid) to make this easier. Don’t be stingy with the lubricant!

• Check that you have completely cut away the two plastic supports on the right side, otherwise, it may be difficult to get the seal through. Description

  Detailed Troubleshooting for Error Code E:15 (Aquastop Activation)

Error code E:15 signals a critical safety intervention within your appliance. This code specifically indicates that the internal water detection system, often referred to as the Aquastop safety feature, has sensed an unusual accumulation of water in the base pan (sump) of the dishwasher. This condition is almost always caused by an internal water leak. When the float switch in the base pan rises due to excess water, the system immediately shuts off the water intake valve to prevent flooding outside the appliance.

Visual indicators that accompany the E:15 code often include the illumination or flashing of the Tap Symbol (indicating a supply issue, though here it relates to water mismanagement) and the “End” light remaining illuminated, signifying the cycle has been halted by a safety mechanism.

What you can do:

1. Remove the Water from the Bottom of the Dishwasher: Before attempting any further diagnosis, you must physically drain the water that triggered the Aquastop.

   • Disconnect the appliance from the electrical supply for safety.
   • Carefully tilt the dishwasher forward or backward slightly (depending on installation constraints) to access the base area where the water has collected.
   • Use a towel, sponge, or shop vacuum to meticulously soak up all standing water from the bottom tray beneath the main washing tub. It is crucial that the base pan is completely dry; otherwise, the safety switch may remain engaged, preventing the machine from restarting even after the primary leak is fixed.

2. Locate and Repair the Leak: Once the water has been cleared, the root cause—the leak—must be identified and addressed.

   • Inspection Area: On many models, particularly those featuring a stainless steel base pan underneath the main housing, the most common area for this specific failure (E:15) is the junction point where the plastic sump or tub structure meets the metal base. Water tracks along internal hoses or fittings and drips into this area.
   • Repair Solution: If the leak originates from this central junction point, a specific service repair kit, which includes an essential supplementary seal or gasket, is often required to permanently stop the water ingress between the plastic and metal components.

Note when installing the repair kit (Seal/Gasket Replacement):

The successful installation of this replacement seal often requires careful manipulation due to tight clearances within the machine’s housing.

• Lubrication is Essential: The new seal must be carefully guided and inserted through two very narrow access openings designed to pass it into position between the two housing components. To significantly reduce friction and prevent tearing or forcing the material, apply a suitable lubricant liberally to the edges of the seal. Use a high-viscosity lubricant such as rinse aid; do not hesitate to use an ample amount of lubricant to ensure smooth passage through these tight channels.
• Preparation of Supports: Before attempting to insert the seal, thoroughly inspect the right-hand side of the installation area. You must verify that the two designated plastic support projections (molded supports often used for shipping or initial assembly) located on the right side have been entirely and cleanly severed or cut away. If these supports remain partially or wholly intact, they will obstruct the path of the new seal, making it nearly impossible to correctly position the component, leading to potential damage to the new seal or an incomplete repair.
