Warning!
Installation aids that contain silicone, e.g., silicone grease, are not suitable
for use in dishwashers because of the damage they can cause.
If, e.g., hoses or seals are treated with silicone in order to facilitate
installation, this could jam the circulation pump. Furthermore, ingredients in
silicone grease can evaporate and damage electrical components such as
heater relays.
4.13 Circulation Pump Removal
Warning!
MPPW circulation pump only:
In the open motor housing, there is an electronic module circuit board (PCB)
which must be protected from moisture and water ingress in order to avoid

When installing the circulation pump, it is important to first install the sump
seal on the pump. Then slide the circulation pump with seal into the sump
housing and secure the pump.
Important!
During reassembly of the circulation pump ensure:
1. A new seal is installed
2. The seal is seated correctly in the pump housing cap
