Bosch's genuine repair set 12005744 contains the seal for the pump sump, the area in the base where water collects and the pumps connect. It is listed for the SMV88TX01A, the SMU68M15AU and the SMI50E25AU as well as many SMP46 series models such as the SMP46MW03S, SMP46TS01S and SMP46TW00S. Use the E-Nr and FD numbers on your door label to confirm the match.

Bosch dishwasher leaking or showing E15?

The sump sits under the filter and collects water before the circulation pump sends it back to the spray arms. Where the sump meets the pump and the tub base, a seal keeps that water in. Once the seal ages or distorts, water seeps into the base tray. Bosch dishwashers have a float switch there, so even a small leak can trigger the anti-flood protection, stop the cycle and run the drain pump non-stop, often with an E15 code. Puddles on the floor or a damp smell under the machine are other signs.

Before you replace the sump seal

Unplug the dishwasher, turn off the water and pull it out from the cabinet. This is an involved job that usually means lowering the base or laying the machine on its back, so take photos at every stage. Dry out the base tray and float before testing, otherwise the anti-flood fault can persist even after the leak is fixed.

Questions about this part

My Bosch shows E15. Will this kit fix it?

E15 means water has reached the base tray, so it only tells you there is a leak. A worn sump seal is one cause, but hoses, the pump or the door seal can also leak. Find where the water is coming from before ordering.
