The Keurig leaks water during the pump operation, I have replace water resivoir thinking it was o rings. Water leak continued. I took keurig apart and is seems to have a back leak from the water pump, when water is pumped in heat resivoir some water reverses direction and back leaks out of bottom of keurig, at the point of water filter. I am unsure of which parts I should change. Can you give me some suggestions? I don’t know if it is worth salvaging coffee maker……but I hate just chucking things in the trash.
It looks like a lot of the models use the same water pump. Ebay sells these for around $15-$20 http://www.ebay.com/bhp/keurig-water-pum… iFixit has a guide for the k75 that may be similar to your model on replacing the water pump. Keurig K75 Water Pump Replacement
