How do I tell if my machine is a 60 or 50 series?

There will be a three-digit number with the letter "P"after it (example 550P). It's on the same label as the serial number. If the second and third number are 50 then it's a 50 series (example 550P). If the second and third number are 60 then it's a 60 series (example 560P).

My lid won’t come off. I wanted to wash this before use but the lid cannot be opened. Is this a defect or design?

The latch that you press lightly is accessed through the round hole on the top & hangs down into the tank (it is NOT the two clips on the outside back; those function similar to hinges). To replace the lid, attach the lid first with those two tabs at the back, then gently swing down until the lid quietly clicks. It took us a while to figure this out, and it is very easy to unlatch & latch again. (Things usually ae when you do them right! ;-)
