In a water-bearing household appliance with a liquid container filled through a valve in a liquid feed line, and in which a liquid filling level is detected for monitoring at least one safety level of a safety device, the safety device includes an optical light guidance system for reflecting a light beam by which the filling level is detected with the aid of a change in the reflection response on at least one reflecting site and is used to monitor the safety level. As an optical light guidance system, the safety device offers the advantage of dispensing with moving mechanical components&#x2014;for example, a float, a level switch, an operating lever, an operating rod, etc.&#x2014;to reduce the risk of mechanical defects that are associated with a substantial outlay on repair time and costs to a minimum or to completely eliminate the risk.
