after removeing the mounting and trim screws,water lines and associated wiring, the unit slide easily from under the counter then the fun began.
After several years of being exposed to the terrible water here the parts had become covered in lyme scale.
to make a long story short, most of the parts came out with minor difficulty however the pump motor shaft had corroded and lodged into the pump impellar.
This made removal of the pump motor impossible with out cutting off the end of the impellar and driving the pump motor shaft out.
This is NOT something you want to do.
It seems the engineer who designed the pump motor had it's casing made of plastic.
Driving the pump motor shaft out of the impellar caused the back of the motor houseing to break thus rendering the pump motor useless.
Lesson: If it becomes necessary to cut off the impellar of in the pump housing you must completely split the impellar in two parts.
This I repeat is NOT something you want to do.
I recommend replaceing both motor and pump assembly as a unit.
