I used a flat head screwdriver and pushed it all the way through. It made soem noise for a few seconds and it went away. All is back to 100%. Warranty is void if any foreign matter causes a problem and they will charge you over 110 dollars to tell you that. I took a chance i saved 110 plus labor. Good luck. It still work fine. No more cleaning the fish tank in the sink.
