I am trying to diagnose an intermittent error message with a Fisher & Paykel DW920 Dishwasher.
I found the diagnostics manual, and in the section on checking the operation of the wash pump it recommends that I "check labyrinth plate".
(Click to enlarge; see box in bottom right corner, second from right.)
I don't know what that is. I have been unable to find a description. The closest I have come is someone trying to sell me a replacement.
What is the role of a labyrinth plate, and where can I find it to make sure it is properly serving that role?

The part is the PUMP INLET PLATE. It acts as a filter and has a tortuous path for fluid and can become clogged. It is attached to the Impeller assembly
