I have one of the Riptide upgrade kits attached to my March pump body. My last brew day, while I was recirculating the mash, I heard the dreaded "screeeeeech" and immediately shut off the pump. I assumed I had sucked in some air somehow, but when I tried to turn the pump back on after ensuring the head was flooded, the whole pump was locked up. Cursing under my breath, I pulled the pump head off and found pieces of a black washer jamming the impeller. After I cleared those out, I flooded the pump again and it started pumping normally.
I'm trying to figure out where this black washer came from. It kinda looks like it came off the back end of the impeller, but I can't find any pictures online to confirm. Can someone with a riptide take a look for me and see if there is black washer glued to the back end (toward the motor) of the impeller?
This is NOT the smaller, stainless washer that goes on the shaft, that remained in place. I attached some pics to show what I mean.
