This dishwasher was making loud noises during wash cycle. I suspected something stuck in food grinder so I took it apart and did find a piece of broken glass stuck near grinder and the grinder blade itself was bent slightly at the tip, suggesting something hard had passed through. Put it back together and it worked, but the next day the wash cycle quit working and I now think maybe the pump (impeller maybe) is bad, maybe the noise was really the pump going out. Any suggestions?
