No, this is not normal.
Cause usually: Pad holder/strainer clogged or calcification → this causes too much water to run through and the coffee becomes thin. Clean the pad holder + descale the machine, then it should work again.
The Philips Senseo Original Plus is a pod machine specially designed for SENSEO® pods. According to the information available, Lavazza pods are not compatible as Lavazza uses different systems such as Blue, A Modo Mio and Espresso Point with their own pod formats. The SENSEO® machines require flat pods that do not match the Lavazza capsules.
If you are unsure, I recommend checking the exact name of the Lavazza pods or asking in the Community for experiences. The official information from Philips does not confirm Lavazza compatibility.
The designation "EU version" refers to the specific version of the product designed for the European market. This version complies with the technical and legal requirements of the European Union, including the mains voltage of 220 to 240 volts.
