That does NOT sound like kettling/scale noises at the beginning (0:06 to ~0:45). It sounds to me as if a solenoid is attempting to open/close and is suddenly released; from about 1:00 on it sounds like kettling. Does the machine work fine otherwise? (ETA - don’t be alarmed; if Dave thinks it’s OK, his opinion on what is a ‘normal’ noise is worth 1,000,000 times mine)
Two years with Lockhills, you probably have a fair amount of scale anyway, especially if you use steam, so a descale is not a bad idea.
