What else belongs to the dishwashers and dishdrawers
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.

About Fisher & Paykel dishwasher error code F40
What F40 means on a dishwasher
Water flow error. This is the maker's own wording from the Built-in drop-door dishwashers user guide, not an interpretation of it.
What to do
- Switch the dishwasher off and on again.
- If the code persists, it needs a technician.
Note the code down before you clear it. On this maker it is the one piece of evidence that disappears the moment power is cycled, and it is the first thing anybody will ask you for.
The same number means something else on another machine
F40 is not one condition on this maker — it is 3 of them, keyed to the appliance rather than to the number. See the same number on a freezer, the same number on a refrigerator. If the page you arrived from was about a different machine, it was describing a different problem.
What the repair is
Conditions in this family end at Dishwasher control & motor repair more often than anywhere else. The figure on that page is a starting point; the exact cost is confirmed after an on-site diagnostic and agreed in writing before anything is opened.
