Hot water connected but does not fill into the drum? The machine will provide us with a cold wash but on the warm and hot settings the hot water dies not pull through the connection

Turn off the water valves which supply the water to washer hoses. Switch the hot and cold water supply hoses and tighten. Turn the water valves back on and try to run a wash cycle using cold. If hot water only is entering the wash tub the water supply is ok. If this is the case you can unplug the washer and turn off the water valves. Remove the washer back cover and follow the water connection for the hot water. The water solenoid valve will have two electrical wires connected to it. Interchange the hot water solenoid wires with the cold water solenoid connection. Connect the water supply hoses hot to hot and cold to cold then plug the unit then test the washer on the cold wash. If the problem persists it could be a water hose restriction or the timer circuit could be defective. If you have hot water at the normal pressure purchase a new hot water solenoid valve. With the electrical cord unplugged be sure to restore the correct wire connections on the hot and cold water solenoid. To replace the hot water solenoid remove the hose clamp and hose to replace the old valve. Connect the unit to the water and electrical outlet. Turn on the water and test the unit for leaks being careful not to touch any electrical and moving parts. If all checks ok and the correct temperature work, unplug the unit and reassemble.
