Hi Mory

Can you give us some more detail. When you say it will not fill up, do you mean that the water comes in and then goes out? Or do you mean that water will not turn on at all. Is this is the case, is it with both the hot and the cold? Have you checked your hoses and inlet for obstructions?

Anyway, give us as complete a picture as you can and then we can probably tell you how to fix the problem. Should not be difficult or expensive.
