I have removed the hose from the tank with the check valve and cleaned the hose and ck valve. The check valve seemed to be working properly and was put back in the hose in the proper direction. I put the hose back in the coffee maker and tested with water. It pumped ok the first time and after it cooled down I tried it again and it would not pump until I lifted the back of the coffee make about 1/4 inch off the counter and let it drop. It started pumping water as it should. I think the ck valve is sticking. Is there a replacement ck valve available? Thanks - Wayne
