Second Senseo coffee machine to become unusable battery a little over a year after buying! (Philips HD7830) These are the contacts of the reservoir that are no longer and prohibit the operation of the machine! It is a shame considering the price (about 100). It's new and more because a friend was one of the first Senseo (over 10 years) still works satisfactorily! Shame on Philips is perhaps to mask its practices that mark changes constantly references its models ...
