What E18
actually means.
E18 means the water level in the tub is too low, or water is not being pumped around properly. Bosch asks for a supply flow of about 10 liters a minute.

Before you book,
in this order.
Each step comes from Bosch's own guidance for E18 on its dishwashers. Follow it to the end: the last card says whether this is a visit.
Turn the supply valve fully on; a half-closed valve can starve the fill.
Check the inlet hose for kinks or damage.
If the supply is strong and the hose is sound, book a visit.

It usually turns into fill and water valve repair. Book with the code and the model number.
What not to do
E18 does not automatically mean a part inside has failed; both of Bosch's checks are outside the machine.
