Sump Seal Repair Kit
This kit addresses the most common mechanical leak path in Bosch dishwashers where water bypasses the primary sump gasket. The supplemental silicone seal creates a secondary compression barrier between the tub floor and the sump assembly, preventing water from reaching the base tray and triggering the E15 float switch. This is a targeted engineering fix designed to rectify seal compression loss due to thermal cycling.

Safety Float Switch
If the base pan is dry but the E15 error remains, the mechanical microswitch or the polystyrene float itself may be compromised. Residual grease buildup or mechanical sticking of the lever can keep the switch in the 'activated' position even after water has evaporated. Replacing the switch ensures the control board receives the correct binary signal regarding the base pan state.

Drain Pump Gasket
The drain pump housing utilizes a rubber O-ring that can fail over time due to chemical exposure from detergents or particulate abrasion. If this seal fails, water will leak directly from the pump volute into the drip tray during the drain phase. Replacing the gasket restores the watertight integrity of the high-velocity discharge path.
