Doing the Bump and Grind!
Bobby,
These pumps, as you may know, are only 1/5 hp so you cannot expect a hurricane in a box from any of the WP tall tubs!
The pumps in these units are very prone to clogging as they are actually protected by at least one if not two pump protector plates inside the pump housing
Once you collect enough crap on top of the protector plates, the pump will give up the ghost and pump little or no water at all.
If you have taken the pump apart at all, you will see that there is a cover over the pump intake and chopper/screen assy which is held in by 1 torx screw. You do have to remove the upper feed tube and the 4 screws which hold the top strainer in place to see down into the sump.
If you remove the strainer first, you will immediately see if the protector is clogged with debris. I have seen this over and over and even clogged my own machine up 2 weeks ago when I threw all my barbeque stuff in there. I clogged the protector plate with pieces of rust and burned off food. I could actually hear the water pressure diminishing as the cycle went on and there was carbon and rust bits all over the tank and door.
I disassembled it and sucked it clean with my small shop vac and did a quick rinse in it and the machine came out spotless.
These pumps do a good job considering what we expect of them but they are not made to grind up anything harder than potatoes and starches in my opinion.
The parts breakdown for your model shows the 2 bladed cutter but K/A added 2 more blades to it to supposedly make it more effective.
It is an easy part to change so I would tackle it yourself. Just work with the parts diagram and you will be fine.
It also appears to have an override mechanism built in to it so it won't jam up but rather slip if it encounters something it cannot handle. It slips right into place once you get the cover off the pump intake area.
You can find a parts breakdown on the K/A website or at Sears.com/parts.
Let us know if you resolve the issue
