My Silvia has started making a strange noise - its like the normal pump sound but higher pitched, tinny & vibrating. Its not necessarily louder than the normal pump sound just harsher. It still works fine when it makes this sound and it doesnt happen always. The machine is kept clean - its back flushed nightly with water & weekly with solution & it was descaled not that long ago.
Any ideas?
Thanks
