How To Fix A Leaky Bunn
 

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.

3-minute coffee vs 15-minute coffee.
But the counter is dry! :lol:

Is JB weld food-safe?

Where I used it was where the cold water enters the hot water tank. It dries hard, so I doubt there is more than the slightest leaching, if any.
