My 5 month old 6910 developed a small tear in the group seal, enough to spit hot water out of the group head when pulling a shot.
Sunbeam were not interested in replacing it under warranty so I purchased a new one from the authorised service agent. They supplied the familiar blue seal but the package also contained 2 translucent, thin rubber rings that fit perfectly over the blue seal where it sits against the body of the machine.
Are these spacers that can be used when the seal or collar wears? I installed one and it made it too tight for the porta filter. All ok without it though.
