The 'perviously owned' BUNN coffee maker we inherited from gramma developed a leak.
A small puddle formed behind it during brewing so I figured I'd fix the small leak before it became a big leak.

Remove top, then remove screws and hollow bolt holding water-filling tray to the warming tank.
The crud on the left is mud, the right is mineral build-up.
They apparently poured old coffee in it....

Cracked, rotted plastic, caused by constant heat of hot water tank.............................................. ...That stayed on the tank.

Mineral build-up inside the warming tank. Black minerals? Methinks the housekeeper recycled coffee. It was so hard I couldn't scrape or chisel it away.

It now leaks 2-cups.
Priceless.
