Washing machine doesnt seem to be heating up the water

Hi. Washing machines are dependent on the water supply for their heat. If it isn't getting hot, it's from lack of hot water. Put the machine on a setting requiring only hot water for the initial fill, and start the machine. If the water is at a low or no flow rate, proceed as follows: Unplug the washer, close and disconnect the hose from the hot water faucet. Inspect the inside of the hot water hose; there is usually a screen in the end to catch scale and sediment. If you see anything there, remove the washer and screen, and clean it. Reinstall the hose, and disconnect the hose at the washer end of the hot water hose. Open the faucet, and discharge some water into a bucket. If there is no water, you may have a plumbing issue, so I'd back up to the faucet and check. If you do have water there, inspect the solenoid valve inlet (where the hose connected) for another screen. Clean as before. If debris was found at either location in a sufficient quantity to obstruct your water flow, reconnect the hose, and try to get hot water into the machine again. If no hot water will enter the machine, the issue is probably with the solenoid valve. If you have an electrical test meter, you can test the valve, or replace it. Any appliance parts supply house will have your part.
Best regards, and good luck. --W/D-- Please feel free to rate this solution, and let me know what you find out.

Is this a dishwasher or a washing machine ? dishwashers heat the water, washing machines take the water from your hot water tank.
