This popular superautomatic is simple and straight forward to use, but we often get questions around how to care for it. In addition to regularly removing the brew group and spraying it down, cleaning the dregs box and the drip tray, you'll need to descale the Vienna every 1 - 3 months (depending on the mineral hardness of the water you're using). Remember: Descaling isn't based on usage, but on timing. If you're not using the machine, water is still sitting in the waterworks and scale can build up. If you use your machine very rarely, it may prompt you to descale less regularly then you might need to, so using the general 3 month rule of thumb is always a good idea. Watch Gail take us through the process.
