If you've recently started having problems with your washing machine water temperature, you may be wondering how to go about fixing it. If so, you'll be pleased to learn that fixing your washing machine water temperature can be a fairly simple undertaking, provided you have the right set of tools and a handy instructional guide at your disposal. So if you're looking to fix your washing machine water temperature in a timely and stress-free fashion, simply read on to learn everything you'll need to know.

Step 1 - Take the Necessary Safety Precautions

Before you can begin fixing your washing machine water temperature, you must first make sure that your washing machine is safely turned off and unplugged and that the device's water supply has been shut off. When working with electronics, particularly those that involve water, safety should always be your number one priority. Once all the necessary disconnections have been made, you will be free to proceed on to the next step.

Step 2 - Check Your Washing Machine's Supply Hoses for Kinks

As strange as it may sound, a lot of water temperature issues are the result of kinked supply hoses. So before proceeding any further, confirm that your washing machine's supply hoses are free of kinks. Should you spot any kinks, use your hands to carefully straighten them out. More severe kinks may require you to replace your hoses. If kinked supply hoses are not the cause of your problem, proceed with the next step.

Step 3 - Check Your Washing Machine's Supply Hoses for Clogs

Perhaps the most common cause of water temperature problems is supply hose clogs. Begin this step by unscrewing your washing machine's supply hoses from the device's faucets, then allow them to drain any residual water into your bucket. Once the hoses have been fully drained, use your screwdriver—or your hands, depending on what brand of washing machine you own—to remove the hoses from your washing machine's inlet valves. Having fully removed your supply hoses, use your screwdriver to pry out their filter screens, then check the screens for clogs. If your filter screens look particularly dirty, that may be the source of your water temperature problem, so be sure to thoroughly rinse them under running water before reattaching them. In addition, if the filter screens look particularly worn-out, it is strongly recommended that you replace them. Filter screens are fairly inexpensive, so if your current screens appear battered, don't be a penny-pincher.

Before reattaching everything, check your supply hoses for any clogs. Should you locate any, carefully attempt to fish them out. Alternatively, you can also try flushing them out by sending a steady stream of running water through the disconnected hoses. Once all the necessary components have been cleaned, dried and securely reattached, you may plug your washing machine back in and turn on the device's water supply. However, take care to thoroughly mop up any spilled water in the vicinity of your washing machine before plugging the device back in, as this tends to be a wet job. Also, when reconnecting your supply hoses to your washer's valves, take care not to cross-thread them. Should your washing machine water temperature problems persist, you may want to enlist the aid of a licensed professional.
