Our dishwasher is on the blink

Came home today to find our dishwasher showing an error message F70.
It's a Miele G2220 SCi model, and the error message indicates that the "Waterproof System" was activated. ie, there may be moisture in the circuitry or some water-release valve has ruptured, or ... well, you get the idea.
Needless to say, I called the retailers from whom we bought it, and they told me to call on Monday morning to inform the right people (no tech support folk there on Saturdays). We bought it last year January, so it's still under warranty [2 years], and someone from Miele Switzerland will hopefully come over sometime this week to fix it ...
