The washer won’t start.

Troubleshooting a washer that doesn’t start can be as easy as pressing a button or unplugging a power cord. However, if the underlying cause of the problem is the power source, professional services are a must. 

Let’s take a look at the most common reasons why a washer won’t start.

CausesSolutions
Insufficient Power• Plug the washer into a grounded 3-prong outlet. Never remove the ground prong.
• Don’t use an adapter or an extension cord.
Tripped Circuit Breaker• Locate the circuit breaker and identify the one that keeps tripping. The switch would be out of place when a breaker trips.
• Move the switch on the circuit breaker to the OFF position.
• After a few seconds, flip the switch back to the ON position.
• Plug in your Whirlpool washer. Confirm that it can turn on and operate properly.
• Turn on the lights and plug in the other appliances in the circuit. 
• If the circuit trips, the appliance or light you plugged in may have faulty wiring or overloaded the circuit.
• Contact a licensed electrician who can help you diagnose and resolve the issue.
Locked Control Panel• To disable the Control Lock function on a Whirlpool Duet washing machine, push and hold the End of the Cycle Signal for 3 seconds. 
• The Control Lock indicator light will turn off once the function is disabled.

Insufficient Power

A Whirlpool Duet washer has its own electrical requirements, which you must comply with to keep your appliance in good working condition. At the same time, it reduces the risks of electrical shock, fire, and death.

Solution: First, check if the Whirlpool Duet washer’s power plug is loose, then plug it in properly to prevent further delays. 

Make sure to meet the following electrical requirements.

  • Plug the washer into a grounded 3-prong outlet. 
  • Make sure it is a 120-volt, 60-Hz outlet.
  • Never remove the ground prong.
  • Never use an adapter or an extension cord.

Tripped Circuit Breaker

A tripped circuit breaker can cause a partial power outage in your household. If only one part of the house has no power while the rest of the house has, you most likely have a tripped circuit.

Resetting the breaker should resolve your problem. However, to prevent it from recurring, you must avoid overloading the circuit. 

You can start by moving major appliances like your washing machine to their own dedicated outlets. 

Solution: Turn off all the lights and unplug the appliances connected to the tripped circuit breaker. Follow these steps to reset the circuit.

  • Step 1: Locate the circuit breaker in your household and identify the one that keeps tripping. The switch would be out of place when a breaker trips.
  • Step 2: Move the switch on the circuit breaker to the OFF position.
  • Step 3: After a few seconds, flip the switch back to the ON position.
  • Step 4: Plug in your Whirlpool washer. Confirm that it turns on and operates properly.

If the circuit doesn’t trip, your washer isn’t the problem. It should function well if you plug it into a different circuit.

  • Step 5: Turn on the lights and plug in the other appliances in the circuit. 

If the circuit trips, the appliance or light you plugged in may have faulty wiring. Or, it may have overloaded the circuit, causing it to trip.

Contact a licensed electrician who can help you diagnose and resolve the issue.

Locked Control Panel

Your Whirlpool Duet washer has a Control Lock function that prevents unintentional changes to the settings. It is quite useful if you have kids or pets around.

If the Control Lock function is activated, the control panel will not respond to your functions. All the buttons on the panel will be disabled until you turn off the function.

You can check the Control Lock indicator light on the panel to confirm that the function is activated. 

Solution: To disable the Control Lock function on a Whirlpool Duet washing machine, push and hold the End of the Cycle Signal for 3 seconds. The Control Lock indicator light should turn off.

The washer has excess suds.

Do you notice excess suds in your drum? Your washing machine is most likely fine (for now), but you have to resolve the problem and prevent it from recurring to keep your appliance in peak condition.

Laundry errors like using too much detergent or using the wrong kind are often the cause of excess suds. When corrected, the problem should no longer recur. 

CausesSolutions
Wrong DetergentOnly use high-efficiency detergent for your Whirlpool duet washer.
Too Much Detergent• Follow the detergent manufacturer’s instructions closely when determining how much detergent to use. 
• Never go over the max line in the dispenser.

Wrong Detergent

High-efficiency washing machines like the Whirlpool Duet use about 80% less water compared to traditional top-load units. Since it uses lower water levels, it needs a low-sudsing and quick-dispersing formula.

Using regular detergent on an HE washer will create an excessive amount of suds, which will not clean your clothes. You’ll have to wash your clothes again and clean up all the foam in the drum.

Solution: Use a high-efficiency detergent for your Whirlpool Duet washing machine. Choose good quality detergent to prevent damage to your washer.

Quick Note:
If an HE detergent is unavailable, use ½ of the recommended amount for your laundry load. As much as possible, avoid detergents meant for hand washing purposes as they can cause oversudsing in front-load washers.

Too Much Detergent

Too much detergent won’t produce cleaner clothes. Unfortunately, it does quite the opposite because it prevents detergent from dissolving properly, leaving a slimy, chalky residue all over your clothes.

Solution: Follow the detergent manufacturer’s instructions closely when determining how much detergent to use. Never go over the max line in the dispenser.

Type of DetergentHE Washers
Pod1 per cycle
Liquid2 tablespoons
Powder2 tablespoons

Run hot or warm water settings for cleaning purposes. Detergent dissolves easily in hot or warm water, which can help reduce the build-up of residue in your tub.

The washer is slow to fill or won’t fill at all.

If your Whirlpool Duet washer is slow to fill or not filling at all, you most likely have an obstruction caused by dirt or detergent build-up. A thorough cleaning cycle is often enough to resolve your problem.

However, if the root cause of the error is a faulty component, you must replace it to keep using your washer.

Here are the most common causes of filling errors on a Whirlpool Duet washer.

  • Step 11: Turn it on and run a test cycle to check if the washer fills and starts.

Clogged Water Lines

Obstructions are common causes of filling problems in washing machines. Sometimes, dirt, lint, and other foreign substances can get lodged into the supply hoses, restricting the flow of water into the tub.

As a result, your washer will be slow to fill or will not fill at all. An error code should appear on your unit’s display to indicate this problem.

What you’ll need:

  • Pliers
  • Bucket

Solution: To remove obstructions in your washer’s water lines, follow these steps:

  • Step 1: Disconnect the hot and cold fill hoses from the washer. Use pliers, if needed.
  • Step 2: Place the hoses over a laundry tub, bucket, or drain pipe. 
  • Step 3: Turn on the supply valves and run the water for a few seconds to clear the lines.
  • Step 4: Reconnect the hot water fill hose to the inlet valve to the right. Screw the coupling by hand until it is snug, then secure the connection using pliers.
  • Step 5: Repeat the same step to connect the cold fill hose to the inlet valve on the left.

Quick Note:
Replace the water inlet hoses every 5 years to minimize the risk of malfunctions. If you notice cuts, bulges, and other signs of damage, replace the hoses immediately.

Poor Water Pressure

According to Whirlpool, your water pressure must range between 5-100 psi (34.5–690 kPa). If your household can’t meet the minimum requirement, you’re going to have trouble filling your washing machine.

On the bright side, there’s nothing wrong with your washer. You just have to fix the water pressure in your household to keep using your appliance.

Solution: Call a licensed plumber who can resolve your household’s low water pressure problem. Don’t attempt this fix yourself, if you have no experience or knowledge in this field.

Quick Note:
According to Whirlpool, you should connect the washer directly to its water supply to optimize its performance. Using anti-flood devices and controls may affect its efficiency, which can lead to malfunctions.

Faulty Water Inlet Valve

A water inlet valve controls how much water flows into your washing machine. If this component is defective, you will experience leaks or filling issues.

There’s no way to fix a faulty water inlet valve, but you can replace the old part to resolve the problem. Just make sure to get the right part for your Whirlpool Duet model.
