No, there should be a label there, if it's not there, it's been removed.
There's another label on the rear.
However, try this.
Take the dispenser drawer out.
Unplug the appliance.
Open the door, take the door seal retaining ring out.
Peel the door seal off.
Take the door lock screws out.
Take the plastic panel below the front panel off.
Take the screws holding the front panel on out.
Take the bottom right screw out of the dispenser.
Push the front panel down and lift it off.
You can now access the pump and housing.
Disconnect the hoses and wiring.
Take the assembly out.
Remove the debris through the hose ports.
Take the cap off.
Clean it all out.
Clean out the hoses too.
Reassemble and try the machine again.
Hope this helps
