The automatic purge cycles and flushing the waste bin consume a lot of water, so it is essential to install it near a sink and be prepared to fill and empty frequently, but it is not binding, I personally do each morning.
Small flat, after a little more than a year of loyal service, a mechanical part broke manufacturer warranty but worked perfectly: a phone call, toll-free removal of the machine and return to my home a few days later in perfect condition. I feel that the case was due to a buildup of coffee grounds in the internal mechanism of the machine, I do not know if the repair has corrected this problem but I will be vigilant on this point in the future.
