If it works: You have a clear reason to replace the hot water fill hose rather than guessing.
If it doesn’t: If the hose looks fine and the washer still will not fill with hot water, the problem may be the supply valve, inlet screen, or water inlet valve instead.

If it doesn’t: If the shutoff valve will not close fully, stop using the washer until the valve issue is fixed.

Yes, if only the hot water hose is damaged or restricted. If the cold hose is the same age and condition, many homeowners replace both at the same time to avoid another leak later.
Usually hand-tight plus a small additional turn is enough. If you use pliers, use them lightly. Overtightening can damage the fitting or hose washer.
The most common causes are a crooked connection, damaged threads, a missing or misseated hose washer, or a fitting that is either too loose or overtightened. Shut the water off and inspect the connection carefully.
If the new hose does not fix it, check whether the hot water supply valve is open, whether the inlet screen is clogged, or whether the washer's water inlet valve has failed.
The hot side is usually connected to the hot water shutoff valve and the washer inlet marked for hot. If the valves are not labeled, trace the existing hose before removing it so you reconnect the new one to the same hot side.
