Hi, Rebecca. Here are some possible fixes to your problem:
There is a little hose filter inside the hose attachment on the back of the washer. You can pull it out with a screw driver. Spray it off.
Turn off the water valves. Take the hoses off the washer and check for clogs.
Disconnect the cold water at the back and cleaning out the built -in filter in the back of the machine.
Put the dial just between some of the temperatures
Hope one of these helps you fix your problem.
