Dishwasher Pump Sump Seal Repair Set – 12005744 (Fixes E15)
If your dishwasher is showing E15, running its drain pump constantly, or refusing to start with water sitting in the base tray, the usual cause is a perished seal between the pump and the sump. Water seeps past it into the base, lifts the flood-protection float, and the machine locks itself out to prevent a leak.
Resetting the float only clears the symptom – it comes back within days. This repair set replaces the worn seal itself, which is the actual fix.
What’s in the kit
- Silicone pump sump gasket
- Pull wire for fitting the seal
- 4 stainless steel screws
What this repairs
- E15 error / flood protection activated
- Water collecting in the base tray under the machine
- Drain pump running continuously, even with the door open
- Machine refusing to start, or stopping immediately after starting
- Damp or water marks under the dishwasher with no obvious external leak
What it suits
This seal is used across the BSH group, so it suits a wide range of Bosch, Siemens, Neff and Gaggenau dishwashers, along with other BSH-built brands.
Because the same sump design spans many model ranges and production versions, we do not publish a model list that could mislead – fitment is best confirmed against your specific machine.
Check before you buy: send us your model number and E-Nr (on the sticker inside the door) and we will confirm this is the right repair set for your dishwasher.
