How Dryer Balls Work

**NOTICE**
Due the danger and complexity of electronic equipment repair, the following technical tip is intended for professional reference only. Please refer to manufacturer’s recommendations as Encompass does not guarantee the accuracy, reliability or safety of this information. 

Dryer balls are great for helping reduce laundry drying time. Unlike other drying aids like dryer sheets and fabric softeners, dryer balls don’t contain any harsh chemicals, which make them much better for sensitive skin, as well as the environment. Additionally, unlike liquid softeners and disposable sheets, dryer balls can last for years depending on how often they’re used.

Dryer balls can be used with most hearty fabrics like linen, cotton and polyester. Avoid using them with delicates as they could cause damage. Dryer balls can be washed by hand in hot soapy water or in the washing machine with other laundry items. Before using them again, make sure they are completely dry or they won’t work properly.

Here’s some other helpful information on how dryer balls work and the benefits:

Keep Laundry Separated

The main function of dryer balls is to keep laundry separated during the drying cycle. They bounce around the dryer drum, which helps create gaps between clothes and other laundry items. This enables hot air to better circulate, reducing both drying time and energy costs.

Absorb Moisture

The best dryer balls are made from wool, which helps them absorb moisture from wet laundry, leading to faster drying.

Soften Fabrics

While dryer balls bounce around, they help soften laundry fabrics by gently moving against and through them. This also helps remove wrinkles from clothing.

Reduce Static

Ever felt an unpleasant electric shock when removing clothes from the dryer? Dryer balls help reduce static by moving through laundry items.

Reduce Lint

Lint can develop in the dryer from laundry friction, which is minimized by dryer balls keeping items separate.

How to Use Dryer Balls

For best results, follow these steps:

  1. Add essential oil: Use a few drops of aromatic essential oils directly on dryer balls for a fresher laundry scent.
  2. Use multiple dryer balls: Throw in two to four dryer balls depending on load size.
  3. Start dryer: Once dryer starts, dryer balls will do their thing.
  4. Take them out: After drying cycle, remove dryer balls and store elsewhere.

LG Dishwasher Error Codes

**NOTICE**
Due the danger and complexity of electronic equipment repair, the following technical tip is intended for professional reference only. Please refer to manufacturer’s recommendations as Encompass does not guarantee the accuracy, reliability or safety of this information. 

The AE error code showing on an LG dishwasher indicates there is a leak inside the unit, which activates the float switch. Sometimes this error code can be easily resolved just by  resetting the dishwasher or changing detergents. If the code remains after trying these tactics, there may be an issue with internal components.

This guide applies to all major LG dishwasher models, including:

LDF6810BB
LDF6810ST
LDF6810ST/01
LDF6810WW
LDF6920BB
LDF6920ST
LDF6920WW
LDF7551ST
LDF7774ST
LDF7810BB
LDF7810ST
LDF7810WW
LDF7811BB
LDF7811ST
LDF7932ST
LDS4821BB
LDS4821ST
LDS4821WW
LDS5540ST
LDS5811ST
LDS5811WW

Step 1 – Reset Dishwasher

Start by doing a simple reset of the unit. Sometimes the error code is showing due to a glitch or issue with control board. To reset, turn power off for 10 minutes and then turn back on again. Continue to next step if error code does not go away at this time.

Step 2 – Look for Water in Drain Pan

The AE error code appears when the float sensor detects too much water in the bottom of the dishwasher. Use a heavy towel to soak up any water found in the drain pan and check to see if the error code has disappeared. If not, continue to next step.

Step 3 – Check Cleaning Detergent

Unless using pods or tablets — which usually include the right detergent amount — double check to ensure use of high-efficiency (HE) detergent. Any other type of detergent will cause too many suds to form in the dishwasher drum, causing a water leak. Try changing to HE detergent, if needed, and check the error code again.

Step 4 – Check Dishwasher Spray Arms

Dishwashers have multiple spray arms that distribute water through the unit. If the arms get blocked or moved out of position, water can leak out through the door.

Follow these instructions to check the spray arms:

  1. Remove all spray arms and check for any debris that could be blocking the water holes by running water through them. Use piece of wire to remove any blockages.
  2. Return spray arms to former positions.
  3. Check to see if AE error code still showing.

Step 5 – Check Door Gasket

A defective door gasket is another potential cause of a water leak. The door gasket or “seal” fits around the dishwasher door to prevent leaks. To check the seal:

  1. Open dishwasher door.
  2. Carefully inspect door gasket/seal for any damage and replace if necessary.
  3. If it looks to be in good condition, clean with hot soapy water to remove any debris that could prevent door from closing properly.
  4. After replacing or cleaning door gasket, check to see if error code still showing.

Step 6 – Check Water Inlet Valve

The water inlet valve, which opens and closes for water to flow through the dishwasher, can fail and fill up the unit with too much water. Here’s how to check the valve:

  1. Check to see if water is leaking from valve. If so, it will need to be replaced.
  2. If no leaks, turn water supply off and then remove hose and check filter and hose for leaks.
  3. If any components are damaged, replace them.
  4. Continue to next step if the error code still shows.

Step 7 – Check Float Sensor

The float sensor monitors the dishwasher’s water level. If it fails, too much water may flood the dishwasher and cause leaking. The float sensor can be removed and tested with a multimeter. If faulty, it will need to be replaced.

Follow these instructions to check the float sensor:

  1. Turn off power and water supply to dishwasher.
  2. Remove float sensor from dishwasher bottom.
  3. Test with multimeter. If it has continuity, reattach to dishwasher and move to next step.
  4. If no continuity, replace it and check the error code again.

Step 8 – Inspect Control Panel 

The final option is to evaluate the control panel, which typically will need to be replaced if faulty.

Defrosting the ice maker of a Samsung refrigerator is typically all that’s needed to get it working again.  Defrosting should also be performed when ice builds up on the condenser coils and water leaks. It’s a simple job; below are a couple of ways to defrost an ice maker, along with useful information on maintaining the unit.

This tip covers these Samsung refrigerator models:

RB217ABPN

Reset Ice Maker

The first method to defrost a Samsung ice maker is to reset it. When reset, the ice maker goes into a defrost cycle, which removes any ice that’s built up in the unit.

Here’s how to do it:

1. Remove ice bucket from unit.

2. Locate Test button and press down until it chimes.

3. Ice maker should go into test cycle and defrosting mode.

4. Reinstall ice bucket at start of next cycle so it can collect any water.

5. Once cycle ends, it will chime again, which means ice maker can be used again.

Forced defrost method

If the reset method doesn’t work, try the forced defrost mode, which should clear the ice that has built up in the unit.

1. Find and press Power Freeze and Lighting buttons. If fridge doesn’t have power freeze button, press Energy Save instead.

2. Hold both buttons down for five seconds.

3. Next, press “lighting” button until “fd” displays. Appliance will go into forced defrost mode.

4. Wait approximately 30 minutes for cycle to end.

5. Once cycle ends, wipe ice maker to remove any water. The unit should now be defrosted and ready to use again.

Maintaining Samsung Ice Maker

To help prevent an ice maker from frosting over again and also increase its lifespan, try these tips:

  • If any visible frost on ice maker, use cloth or scraper to remove.
  • Check ice maker weekly and defrost again if needed.
  • Turn off ice maker when not being used. This minimizes buildup and saves energy.
  • Regularly clean rubber seals in ice bucket to prevent frost and other debris from building up.

Samsung Ice Maker FAQ

Why do I need to do a forced defrost of my Samsung ice maker?

Forced defrosting is needed when ice makers become frosted over and don’t operate correctly. This is usually caused by a blocked vent, faulty defrost heater or timer, or dirty condenser coils. Before putting the ice maker in a forced defrost cycle, fix the underlying problem.

What error codes on my Samsung refrigerator relate to the ice maker?

Error codes appear on the refrigerator’s display screen when something is wrong with one of its components. The following error codes apply to the ice maker:

  • 5E – Fridge defrost sensor error.
  • 8E and 14E – Problem with ice maker sensor.
  • 33E – Problem with ice pipe heater.
  • 39E and 39C – Ice maker function error.
  • 40E and 40C – Problem with ice maker fan.
  • 84C – Problem with compressor lock.

How long does it take to defrost my Samsung ice maker?

The forced defrost cycle takes about 30-60 minutes. Turning off the ice maker off can take up to 24 hours to fully defrost.

How often should I defrost my ice maker?

If the ice maker is used regularly, it should be defrosted monthly. If it’s not used very often, it can be defrosted every 3 months. However, if it’s every found to be covered in frost, it should be defrosted immediately. To help maintain the ice maker, check it weekly just to make sure no frost has built up on the unit.

Pressure Test Sealed System with Nitrogen

**NOTICE**
Due the danger and complexity of electronic equipment repair, the following technical tip is intended for professional reference only. Please refer to manufacturer’s recommendations as Encompass does not guarantee the accuracy, reliability or safety of this information. 

**NOTE: Working on refrigerator sealed systems is considered an advanced repair that should only be performed qualified, professional technicians.**

To check for leaks in sealed refrigeration systems, nitrogen can be used instead of air or water because it’s inert, odorless and has low moisture content.  Following are some basic steps for conducting a pressure test:

  1. Attach the service hose to the process stub on the compressor.
  2. Then, attach the service hose to the regulator on the nitrogen tank.
  3. Turn the nitrogen tank on check the PSI. A brand new tank should have about 2,000.
  4. Deliver nitrogen to the refrigerator by turning the T-handle to the right until reaching about 100 PSI. Turning the handle to the left will decrease pressure or turn it off.
  5. With nitrogen now pressurizing the system, check all joints for leaks. Large leaks should be heard on the suction line, but for smaller leaks, bubble testing is required.
  6. As nitrogen leaves the system and pressure further decreases, bubbles become smaller and smaller. The smaller the leak, the smaller the bubbles.

Please keep in mind when bubble testing, the system should always be pressurized. This helps prevent the solution from being drawn into the sealed system, as well as to show the bubbles.
