Same problem and went thru everything before i did the simple thing. Turn it over and open head. Use paper clip or pin to clean out holes on both sides of the pin. The pin is hard to find ( use flashlight and you will see it). Put soda straw on what you cleaned, pinch bottom is straw to make tight seal and BLOW. You can tell it is clear. Turn over and try to brew. I think people have problems because they are not finding the pin that is clogged ( that was my problem). Hope this helps. I was ready to buy new water pump.
