If you're talking about the model shown in your picture, the leak is most likely between the water reservoir and the tank. Bunn uses a soft silicone seal for that connection that gets compressed over time and starts to leak water whenever you make a pot of coffee.

It's planned obsolescence. Bunn won't sell you a new seal. So you have to improvise. But it's simple enough to do.

Remove the top cover and the plastic water reservoir right below it. Don't tamper with the little valve that opens when you close the lid.

Look for the seal. It could be stuck to the bottom of the reservoir, or sitting loosely on top of the metal tank. Make sure to preserve its top-to-bottom orientation (don't put it back in upside down).

Apply a narrow bead of clear silicone into the grooved side of the seal. Press the seal gently onto the reservoir, then apply a thin layer to the smooth side.

Re-install the reservoir and reassemble the unit.

SOURCE: leaking from top of water tank

It sounds like a broken seal/gasket. If you will get the model and date code and contact customer service, we will be able to properly assist you in resolving this problem. The machine carries a 3 year warranty so if it is 3 years old or less, it will be replaced at no cost. If it is over 3 years old, it will be replaced at a reduced cost.

Hoover f7458-900 leaking when placing tank on

Hello! Test the clean water tank to see if it is leaking. Fill the clean water tank with water on both sides. Hold the tank up and observe if water leaks from the valves underneath the tank. If either of the valves are leaking the clean water tank will need to be replaced. To order a replacement tank follow this link > Search Results. If the tank is not leaking, but the cleaner leaks when the tank is placed on it, this may indicate an internal issue with your pump. We would recommend taking the cleaner to a Hoover authorized service center. Follow the link to locate the nearest service center to you. > Service Center Locator Hope this helps!

What could be wrong with my 99 Mazda Protege now? 5 months ago it overheated, replace alternator and belt, now battery wont hold charge and is overheating again, and loosing water coolant.

For a coolant leak you need to check all the hoses and fittings by radiator, heater core, expansion tank for leaks and/or integrity. Also make sure that your water pump is not leaking along with radiator cap and thermostat body. Overheat condition has no effect on battery - if it does not hld charge it is because it is chemically worn out and needs replacement. Until you correct water loss, have extra water in car at all times and run your heater full blast - windows open!!!!
