The canister that holds the water is leaking.
With absolutely no idea what your model is, there's no way to know.
If your Bunn is a residential unit, throw it away and buy a new one. Something has a crack and it's not worth fixing. There's no service/parts support for $100 coffee makers.
If it's a commercial unit, check the water connection in the back. Could just be a water supply line that's developed a leak. If it appears to be coming from inside the brewer, call a service company.
