Just took out the pump and all is clean. Now upon restart I herd the same loud brumming noise. So I opened the back and listened and put my hand on the pump it stopped let it go it makes a loud vibrating sound. So does this mean the pump is done? Reason I havent got a new pump is because its about $70 cnd plus tax 12% and wanted to be sure otherwise its cash out the door. So now would this makes things more cleared that it is the pump that is the problem?
