Whirlpool Washer Not Heating Water? Here's How to Fix It

Is your Whirlpool washer not heating up water?
I know a warm cycle that stays cold can make you think the heater has failed. I would suggest you check the selected temperature, hot water supply, and inlet hose, because a wrong setting, closed supply tap, or bent inlet hose can leave the washer with cold water.

How to Fix a Whirlpool Washer That Won't Heat Water
To fix a Whirlpool washer not heating water, check the cycle, water supply, inlet hose and screens, then have the heating parts tested.
Next, if your Whirlpool washer won't heat water, note whether it is washing in cold water only or the water is not getting hot on every warm cycle.
Check the Wash Temperature
So, select a normal warm or hot cycle instead of a cold, delicate, or energy saving option. Let the Whirlpool washer complete an empty test cycle without opening it while it runs.
However, some cycles use cooler water to protect fabric. Compare the choice with the cycle chart in your manual before deciding the washer will not heat.
On a Whirlpool washer, this cycle setting are easy to overlook as you inspect it.
Check the Hot Water Supply
However, check the manual to see whether your Whirlpool washer uses separate hot and cold hoses or heats a cold supply inside the machine. If it has a hot hose, open that tap fully and run the nearest hot sink tap.
Further, if the nearby tap stays cold, the trouble is in the household hot water supply. A single inlet model needs a technician if its internal heating parts do not warm the wash.

One of these hot water supply check can reveal what changed during your first check.
Inspect the Inlet Hose
Further, follow each inlet hose behind the Whirlpool washer. Straighten sharp bends, free a hose trapped against the wall, and make sure the connections match the labels on the machine.
For safety, turn off the water before moving a connection. Replace a hose that is split, swollen, or leaking instead of trying to patch it.

The inlet hose on your Whirlpool often show a useful clue while you look for the cause.
Clean the Inlet Screens
Remember, small screens where the hoses meet the Whirlpool washer catch grit. A blocked hot side can leave the machine washing in cold water only even when cold filling looks normal.
For safety, unplug the washer, close the taps, and follow the manual before removing a hose. Rinse loose dirt gently, do not pull the screen out, and check every connection for leaks afterward.
Next, if both supplies are weak, read about a Whirlpool washer that is not filling with water.
A few minute spent on the Whirlpool inlet screen can be useful before you decide on service.
Have the Heating Parts Tested
Besides this, if the water is not getting hot after the supply checks, the inlet valve, heater, temperature sensor, wiring, or control may be at fault. Which parts apply depends on the Whirlpool model.
For safety, keep the machine unplugged and ask a qualified technician to test it. Contact Whirlpool first if the washer is under warranty.
