Whirlpool’s HybridCare dryers combine the efficiency of heat pump technology with the power of a traditional dryer heating element to dry your clothes using less energy. However, these high-tech dryers can develop a number of common problems that lead to frustration for owners.
In this comprehensive guide, we’ll explore the most prevalent Whirlpool hybrid dryer problems owners face and provide troubleshooting tips to get your dryer back up and running optimally again.
Problems With Whirlpool Hybrid Dryer
Here is a list of those issues:
- Slow Drying Times
- Not Heating Properly
- Error Code LF
- Reset Button Location
Let’s talk about them in detail.
Slow Drying Times
One of the top complaints among Whirlpool hybrid dryer owners is that it takes too long to get clothes dry. A cycle that used to reliably dry your clothes in under an hour now takes 2 or 3 times as long to complete.
There are several possible causes for longer dry times:
- Clogged lint screen/vent. Over time, lint can build up on the screen and in the ventilation system, restricting airflow. Clean the lint screen before every cycle and scrub it with a toothbrush periodically to remove lingering buildup. Also inspect the vent line and use a dryer vent brush to remove accumulated lint from the entire run.
- Weak heating element. The heating element in a hybrid dryer generates high heat to get clothes dry faster when the heat pump alone can’t keep up. If it loses power, dry times will increase. Have an appliance tech test the heating element with a multi-meter and replace it if faulty.
- Damaged moisture sensors. Hybrid dryers have moisture sensor strips that detect when clothes are dry and shut off automatically. If these are coated in residue or malfunctioning, the dryer won’t know when to turn off. Carefully clean the sensor strips located on the barrel wall with rubbing alcohol and a rag.
- Overloaded drum. Putting too many clothes or bulky items like comforters in the dryer at once won’t allow airflow to circulate effectively. Only fill the drum 2/3 full and break large loads into smaller batches.
- Lint-clogged heat pump. For maximum efficiency, the heat pump component must remain free of lint debris. Clean the concealed heat pump filter 2-3 times per year to remove built-up lint.
- Incorrect vent configuration. The venting setup can severely limit airflow if configured improperly. Ensure the vent line is no longer than 25 feet with no more than two 90 degree turns and no kinks. Transition ducts should be rigid metal rather than foil or plastic.
- Excess lint production. Some fabrics and laundry combinations generate a lot of lint, which can quickly choke airflow through the dryer. Use lint sheets in pockets when drying lint producers like towels and fleece fabrics.
Thoroughly cleaning your dryer vent and components and ensuring proper operating conditions can help your Whirlpool hybrid dryer return to faster dry times. But if problems persist, contact a technician to diagnose and service it.
Not Heating Properly
Lack of heat is the other major performance complaint among hybrid dryer owners. Clothes take forever to dry and come out still damp, indicating the dryer isn’t getting hot enough.
There are a couple key problems that can cause poor heating:
- Malfunctioning heating element. The electric heating element uses high heat to get clothes dry faster when sensor readings indicate the heat pump alone won’t cut it. If it fails to engage and produce heat, dry times are drastically increased. Have a technician test the continuity of the heating element circuit and replace it if defective.
- Failed thermistor. This sensor monitors air temperature exiting the drum and signals the heat pump and heating element when to turn on and off. If the thermistor malfunctions, components don’t switch on properly. An appliance repair pro can diagnose a bad thermistor using a multi-meter and replace it.
- Plugged heat pump air intake. For the heat pump to warm the air efficiently, the air intake must be clear and unobstructed. Lint and debris buildup here will hinder performance. Carefully clean the intake vent with a vacuum hose regularly.
- Refrigerant leak. The heat pump circulates refrigerant to generate warm, dehumidified air. But leaks in the sealed system will lower its efficiency drastically. An HVAC technician can check for leaks, top off refrigerant, and seal any points of loss.
- Weak door seal. If the door seal is loose, warm air will escape from the drum rather than recirculating to dry clothes effectively. Inspect the seal for any gaps or damage and use adhesive to re-secure loose sections. If worn, replace the gasket.
Monitor your hybrid dryer’s performance over each cycle. If weak heat generation develops over time, it likely indicates a faulty component or clogged airflow. Have your appliance thoroughly serviced to restore proper heating function.
Error Code LF
One cryptic but common error code Whirlpool hybrid dryers produce is LF. This stands for “long fill” and indicates the dryer isn’t filling properly:
- Clogged water inlet valve. Hybrid dryers rely on a trickle of water to maintain humidity levels and condense moisture from the air during cycles. But debris and minerals from your water supply can obstruct the solenoid inlet valve where water enters. Shut off the supply lines, disconnect the hoses, and inspect the valve ports for blockages. Clean or replace the inlet valve if necessary.
- Kinked water supply line. If the water supply lines leading into the dryer are pinched shut or crimped, water can’t flow into the drum. Straighten the lines to remove any kinks or tight bends. Check for collapsed sections in need of replacement.
- Pressurized drum. In rare instances, excess warm, moist air in the dryer drum can pressurize it and obstruct the intake of fresh water. Run a pressure release cycle or leave the door open for several hours before the next cycle to relieve any buildup.
- Defective moisture sensors. Dryers rely on moisture sensor strips to detect when to fill with more water. If these sensors are damaged or coated in residue, the LF code can appear even with no actual water flow issues. Carefully clean the sensor strips located inside the barrel with rubbing alcohol and a rag.
The LF code should clear after you’ve corrected the problem inhibiting water flow into the drum. Be sure to run a diagnostic test cycle to confirm all components and valves are functioning properly before resuming regular use. Call a technician if LF errors continue.
Reset Button Location
Like any complex appliance, hybrid dryers can sometimes enter confused states where they become unresponsive or display false error codes. Resetting them can often resolve random glitches and gremlins.
All Whirlpool hybrid dryers have a small reset button located:
- Under the control console – Pull out the dryer knobs to access holes on either side of the console. Insert a thin tool like an unfolded paperclip into the hole to press the recessed reset button.
- Inside the door – Open the dryer door and look along the front edge of the inner door liner for a small hole. Use a paperclip to push in the reset button mounted behind this opening.
- On the dryer back – Some models have the reset button externally on the appliance back, near the motor housing. Simply find and press it with your finger to reset the dryer.
The reset button may feel like pushing in a stiff switch. Hold it down for 5-10 seconds before releasing to complete the reset. Then power the dryer back on and test for normal operation.
Resetting can clear many random glitches, but if error codes reappear, underlying problems are likely at fault. Schedule repair service since persistent issues usually require component replacement or repair to resolve.
Frequently Asked Questions (FAQ)
Excessive dry times are most often caused by a clogged lint screen or vent, weak heating element, overloaded drum, or malfunctioning moisture sensors. Clean the dryer thoroughly, inspect it for faulty parts, and don’t overload it to restore faster drying.
If your dryer isn’t producing sufficient heat, common causes include a defective heating element, failed thermistor, plugged heat pump intake, refrigerant leak, or poor door seal. Have an appliance technician diagnose and replace any faulty parts.
The LF code stands for long fill and indicates that water can’t flow properly into the drum due to a clogged inlet valve, kinked supply line, pressurized drum, or faulty moisture sensors. Inspect the water supply parts and sensors, cleaning or replacing defective ones as needed.
Whirlpool dryer reset buttons are commonly located under the console top, inside the door housing, or on the appliance back. Use a paperclip to press the recessed button and hold for 5-10 seconds to reset your dryer.
