Unless your hoses have a special connector, you can buy standard universal hose replacements at most home improvement or appliance stores. They usually have a red and blue standard hose set and a more pricey braided steel hose set. Unless your hoses take some kind of abuse, the braided steel hoses arent worth the extra cost.

no leaking,just a bearing like sound,alternator?

First, see the Sears parts site for your washer:

Enter your model number (###.######) and you'll see a list of major sub-components with diagrams and parts.

Most likely the braided fuel hose,from the steel line to the flex, has rusted at the connection. That hose won't be avail at the dealer. You will have to remove at the fuel rail and where it is leaking, and make up your own.
Problem is finding the push-on connectors,not having braided hose and heat issues.

Start by replacing the fuel filter and connecting hose at the leak point. It is important to use "fuel hose" and fuel hose clips - which are different to standard hose clamps.

If you have problems with mice - use a steel braided fuel hose - as they can't chew through these ! -

nf means u have a bad water valve u may also have a bad hose underneath the lid as well if u have water in your control

nf is the failure code for [no fill].check your water valve screens for a mineral buildup/blockage.they are where the fill hoses attach to your washer.make sure water is present at washer[run the water from each hose into a bucket].i live in ohio its 0 degrees out side now.i did't know it but there was an air leak near my dishwasher drain hose in the house and water froze in it blocking the drain.i hope this info helps you fix this washer, God bless ,tom

Cleaning brushes don't rotate during cleaning!
It might be a clogged vacuum hose. Does anyone know its whereabouts?

I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure.
The best way to tell if the vacuum hose is clogged is to take a round ball, marble or steel ball or a nut & bolt assm that is about the same size as the vacuum hose opening & drop it or run it thru the vacuum hose and if it comes out the other end the hose is not clogged. If you have a braided hose (cloth on the outside and black rubber in the inside) the inside black rubber or inside of the hose brakes down and starts to leak and the air moving thru the hose will escape thru the hose and reduce suction. Also make sure the suction release valve is closed as well. There are some vacuums that use a braided hose and the only fix to that problem is to replace the hose. Feel free to check with you local vacuum dealer in the yellow pages or call the factory listed below:
