If your washing machine’s water temperatureis wrong, set the controls to the first wash cycle, and then try each water temperature setting. If the hot water setting works but cold doesn’t, or vice versa:
1) Be sure both the hot and cold water faucets are turned on.
2) Be sure the supply hoses are not kinked.
3) Turn off the faucets. Unscrew the hoses from the faucets, and drain them into a bucket. Hold the bucket under the faucets, and test them to make sure they both work and have plenty of pressure. Screw the hoses back onto the faucets.
4) Unscrew the hoses from the inlet valves, and clean the filter screens just inside them; these may be clogged. To do this, pry out the screens with a screwdriver (this can be difficult because the screens may be inside the valves), flush them under running water, and then put them back into the hose. If the screens look defective, replace them. Then screw the hoses back onto the valves. Be careful not to cross-thread the hose threads when screwing them back onto the valves.
5) If the above steps do not solve the problem, call a repairperson. There may be a defective inlet valve or an issue with the controls.
