Question

Hello, I am just received an older dishwasher, the original owner had cut the lines to the fill and drain lines and had somewhat hard wired it into the plumbing in his apartment. I am looking to use it the way it was intended but can not find the information I need to hook it up and I am not sure which lines drain and which fill. One of the hoses are larger then the other (diameter). Ideally I would like to replace the hoses back to the original style but can work something else out if this is not possible. Knowing which one is the right hose would be great.
