Once you've removed the pump housing next remove the diffuser by
unscrewing the two hex screws that hold the diffuser to the seal
plate. Make sure you keep the screws and diffused gasket (the black
o-ring around the diffuser nozzle in a safe place. Once you completely
remove the diffuser, you should see the Impeller behind it.
The diffuser channels water in to the impeller and reduces noise
and improves pump efficiency.
