2 General description The WMF Bistro easy coffee machine is a fully automatic single-cup machine for making Espresso, Café Crème, Cappuccino, White Coffee and Latte Macchiato. Hot water dispensing is also possible. Both coffee beans and ground coffee can be used, coffee beans via the grinders and ground coffee via the manual input. All the coffee and milk drinks are dispensed via a specially designed combination spout, which also enables perfect milk froth and hot milk to be prepared.
3 Warnings Maximum machine safety is an integral WMF product characteristic to which we pay particular attention. In spite of all our safety precautions however, every machine is potentially hazardous if not operated properly. This is why – for your own safety – we have summarised the warnings below and highlighted them in grey throughout the instruction manual. Please also follow the “Safety Instructions” on page 48.
4 Safety instructions General notes 1. At the end of the working day always ensure that the shut-off device on the water pipe supplying the machine is closed and the main power switch to which the machine is connected is switched off and/or the plug is removed from the socket. 2. The component-tested safety devices fitted prevent inadmissible pressure and temperature rise in the boiler. If the safety valve is activated, the machine should be switched off immediately at the customer’s main switch.
Preventive measures to avoid consequential machine damage Any technical devices, particularly large fully automatic machines, are a potential source of danger when operated without supervision. We therefore recommend that the operator takes appropriate action to prevent damage, for instance installing a suitable water detector in the site water supply line.

This should be carried out by approved contractors in accordance with general and local regulations.
