Accordingly, why is my washer using hot water on cold setting?
Some washers have an ATC (Automatic Temperature Control) switch that regulates fill water. Some of these switches are programmed to sense when the water supply hoses are reversed. If the switch on your washer sensed this in error, it would fill with hot water instead of cold. You may need to replace this switch.
Beside above, why am I not getting hot water in my washing machine? If the machine does not fill with either cold or hot water, you must check if the inlet valve is blocked. At times, the hose may be kinked, which can prevent water from entering the machine. To inspect the inlet hose, you must turn off the faucet. Check the wire mesh and clean or replace it if it is dirty.
In this manner, why is my washing machine not using cold water?
Check that the cold water tap for the washer is turned on and also that water is available from the tap. Check that the filter in the end of the cold water inlet hose connection into the washing machine is not blocked. Check cold water tap is working. If they are okay, maybe the inlet solenoid.
Should a washing machine be connected to hot or cold water?
A washing machine is normally connected to the cold and hot water systems, but quite a few will work with just a cold supply while dishwashers usually only need a cold supply. If your machine is supplied from the pipe that feeds your kitchen tap, the water will be at mains pressure.
