Dolce Gusto EDG625.B Melody 3 Coffee Machine, Using NESCAFÉ coffee pod capsules.

Hi all,
Have anyone bought one of these coffee makers?

I bought one on 7th May this year from Currys, I drink the Americano coffee black and consider the cost per cup reasonable, as this uses just one capsule per drink.

I did pay for the "Whatever Happens" insurance just in case!

On 30th July it made a strange noise and no water ran through it (there was water in the tank) then I found I could not open the capsule release lever to remove what I thought might be a duff capsule.

Currys changed the machine no problem, but I have since herd of others having problems and wanted to ask for opinions.
Will they continue to replace the machine with any future faults?
Mick.
