The timeing is off and on it stope before it complete the wash.

It needs a new timer. You can easily fix this but the part can be expensive. New timers can cost up to $100. It may not be worth it. Call an appliance parts store in your area and get a price quote. Have the model and serial number available when you call. If it is more than a few years old try a used appliance dealer, they may sell you a used part. It is easy to replace, just keep track of the wires. Sometimes the part you get will be made by a different compayn than the one you have. This is ok it will still fit. Just match the wire colors or numbers.
