Dishwasher Troubleshooting

**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

Dishwashers are one of the hardest working appliances in the kitchen. When they break down, it’s beyond annoying — who wants to wash dishes by hand?

One of the most common problems with dishwashers is emitting strange loud buzzing noises. This is a clear sign something is wrong and needs to be fixed. It’s very unlikely the problem will just miraculously go away on its own.

There are a few possible causes of buzzing noises, including dishes not stacked properly, machine not sitting level on the ground, pump intake is defective or pump seals are dry. Sometimes, it’s simply a case of general wear and tear, especially if the unit is old. Here are some things to try to stop the sounds:

Ensure Dishes Stacked Properly

The most common cause of a dishwasher buzzing noise is just that dishes aren’t stacked properly. When this happens – especially with plastic cups and containers – they can rub up against another dish and cause a noise. Properly load the unit to see if the noise stops.

Check If Dishwasher Level

It’s possible that the unit is not sitting level on the floor or it’s rubbing against its cabinet or the kitchen bench. Here’s how to check that the dishwasher is level:

  1. Use a bubble level to check balance.
  2. If it’s not properly leveled, adjust the dishwasher legs until it is level.
  3. If it’s level, ensure dishwasher isn’t moving against the bench at the top or sides. If it is, lower the level so there’s a clear gap between the top of the dishwasher and the bench.
  4. If the level is changed, turn on dishwasher ensure the problem has been solved.

Check Pump Intake

The next component to check is the dishwasher’s pump intake, which catches large food particles and other pieces of debris to prevent the unit from getting clogged. Sometimes a small piece of glass or plastic can get stuck in the pump intake, which causes a buzzing noise. When this happens, remove the debris and the noise should stop.

Here’s how to check the pump intake:

  1. Locate the pump intake and open.
  2. Clean it out thoroughly.
  3. Plug back in dishwasher, turn on to a cycle, and see if the noise has stopped.

Dry Pump Seals

If the dishwasher is new or hasn’t been used for awhile, the pump seals can sometimes become dry, causing strange noises when it’s running through a cycle. This is because water usually lubricates the seals, which won’t happen when it’s not in frequent use.

To fix this problem, you need to:

  1. Locate pump seals.
  2. Pour about 1 quart of water into the bottom of the dishwasher.
  3. Turn dishwasher on to a cycle, and check if the problem has been solved.

Dishwasher Still Making Buzzing Noise?

If none of these actions solves the issue, it may just be normal wear and tear that won’t be able to be fixed easily. It may be time to replace the unit if the buzzing sound is unbearable.

LG Dryer Error Codes D80, D90, D95

**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. 

LG dryers are high-quality appliances with industry-leading safety features. The main safety feature they have is the ability to display specific error codes when something is wrong with the dryer or the ventilation system.

This article covers the three most common LG dryer error codes D80, D90 and D95 for the following models:

DLE0442W

DLE2701V
DLE3777W
DLEX2801L
DLEX2801R
DLEX2801W
DLEX2901V
DLEX3001P
DLEX3001W
DLEX3360R

DLEX3360W

DLEX3360V
DLEX3470V
DLEX3470W
DLEX3550V
DLEX3550W
DLG5932S
DLG5988B
DLG5988S
DLG5988SM

Error Codes D80, D90 and D95 Explained

If the control panel displays these error codes, the airflow through the ventilation system has been obstructed by a buildup of lint. The higher the number after the “D,” the greater the obstruction. For example, D90 means there is 90% ventilation blockage, indicating the air exhaust is not able to push enough air out from the dryer.

When these error codes appear, the dryer will turn off to avoid overheating. Dealing with these error codes properly is very important as one of the most common causes of house fires in the U.S. is overheating dryers.

How to Fix Ventilation Error Codes 

  1. Thoroughly clean/remove all lint from filter.
  2. Disconnect exhaust hose at back of dryer and check to see if it is blocked. Remove any debris.
  3. Check wall duct for blockages and remove.
  4. Check outside vent for any blockages and remove.
  5. At this point, the error code should disappear. If need be, turn dryer off and on to remove error code.

LG Washing Machine UE Error Code

**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. 

When an LG washing machine displays a UE error code, it means the unit’s control board has detected an unbalanced load. This prevents the washer from spinning until the load is either balanced or a faulty component is repaired.

Best case, something simple is causing the problem and can be fix quickly. Below are steps to take to determine whether this will be an easy or more complicated repair. This guidance applies to the following LG models:

RLM20K WD-10271
BD WD-11275
BD WD-13276
BDM WD-90282
BD WM2233
HW WM2277
HS WM2301
HR WM2301
HW WM2455
HG WM2455HW
WM2455HW/00
WM2487HRMA/00
WM2487HWMA/00
WM2496HSM
WM2496HWM/00
WM2688HNM
WM2688HWMA/00
WM3070HWA
WM3470HVA
WM3470HWA

Step One – Try Balancing Load

The first step is to just try balancing the washer load or evening out the weight of the laundry. See if there are tangled sheets or other large and heavy items that may be shifted to one side or the other. If it’s a small load, try adding more items to help better distribute weight. After trying to rebalance, start the washer again to see if the error code has disappeared.

Step Two – Check Washer Legs

Next, check the washer’s leveling legs. The easiest way to determine if the washer is sitting level is to use a bubble level device. Place the device on top of the washer; if it’s not level, adjust the legs appropriately. This can usually be done by rotating the legs without having to lift the washer. Also check to ensure the legs are firmly on the ground with nothing beneath them. Once the legs are adjusted, check again to see if the error code is still showing.

Step Three – Reset Washer

If the previous steps don’t help, try resetting the washer to see if the error code disappears. Just turn off the power to the washing machine for a couple of minutes and then turn it back on again. If the error code is still displayed, move on to step four.

Step Four – Check Rotor Mounting Nut

If the basic fixes haven’t worked, it’s time to check some of the washer’s internal components to see if they are faulty. When dealing with the guts of a washing machine, it’s best to enlist an experienced appliance repair professional due to the inherent risk.

First, check the rotor mounting nut, which helps secure the rotor assembly over the stator. Here’s how to check this component:

  1. Turn off power to washing machine.
  2. Remove side panels to access stator assembly.
  3. Locate stator assembly (check service manual, if necessary).
  4. Ensure nut is tightly secured and adjust if not.
  5. While checking mounting nut, check mounting bolts securing stator and tighten if needed.
  6. Turn power on and see if problem has been solved; if not, proceed to next step.

Step Five – Check Suspension Rods

If the unit is top loading, check the suspension rods; continue to the next step if the unit is front loading.

Suspension rods can wear out, causing a washing machine to vibrate and make loud noises. Over time, this can lead to unbalancing and the UE error code.

Here’s how to check the suspension rods:

  1. Ensure power is off.
  2. Remove washer panels to access suspension rods.
  3. Locate rods (consult service manual if necessary).
  4. Once located, check rods for any signs of wear and tear or any type of faultiness.
  5. If rods are faulty, replace them and check error code again. If still displaying, move to next step.

Step Six – Check Shock Absorbers

If the washer is front loading, check the shock absorbers. Like suspension rods, they can sometimes wear out, causing vibration, loud noises and/or unbalancing, which triggers the UE error code.

Here’s how to check shock absorbers:

  1. Turn off power.
  2. Remove washer panels to access shock absorbers.
  3. Locate shock absorbers (consult service manual if necessary). The washer may need to be placed on its side for easier access.
  4. Once located, check shock absorbers for any signs of wear and tear or faultiness.
  5. If they are faulty, replace them and check error code again. If still displaying, go to next step.

Step Seven – Check Hall Sensor

Try checking the hall sensor (sometimes called a rotor position sensor), which monitors the motor operation. When the motor becomes defective, it can trigger incorrect error codes to be displayed.

Here’s how to check the hall sensor:

  1. Turn off power to washer and remove side panels.
  2. Locate the hall sensor (check service manual if necessary).
  3. Once located, use multimeter to test sensor for continuity.
  4. If continuity exists, it is working so move to step eight. If no continuity, sensor must be replaced. Once replaced, check error code.

Step Eight – Replace Control Board

If the error code still displays after trying all previous steps, the final option is to replace the control board. Control boards are difficult to test to find the specific fault, so it’s best to just replace it to see if the problem is resolved. However, this can be an expensive repair, so it might be more economical to buy a new washing machine.

Deal includes support for high-end household refrigeration and freezer products

Lawrenceville, Ga., August 4, 2021Encompass Supply Chain Solutions, Inc., a leading provider of replacement parts and supply chain services for a diverse range of product brands, today announced it has finalized a three-year agreement to provide repair parts support for residential and commercial refrigerators and freezers from Liebherr, a German manufacturer of a wide variety of products.

Whirlpool Dishwasher Pump Replacement

**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. 

When a dishwasher won’t clean dishes, one of the first likely causes is the pump outlet. This part connects the main water supply tube to the pump and spray arms. If it cracks, water pressure decreases and will not properly shoot out of the spray arms to effectively wash food particles away. Here’s how to fix a Whirlpool dishwasher in just a few minutes with replacement part 8194582.

1. Unplug appliance. Even though this repair doesn’t involve electrical components, unplugging or flipping the circuit
breaker to major appliances (especially major appliances with water) better ensures your safety.
2. Access spray arms. Open the dishwasher door and remove lower rack. Unscrew spray arm central piece and fully remove, along with arms and bearings. One metal bearing is in the spray arm apparatus, and the other is below resting on the pump outlet.
3. Remove pump outlet. There are eight screws holding the pump outlet in place below the spray arm apparatus. Use a
screwdriver to remove the screws. Set them aside for later use since the replacement parts do not come with replacement screws. Disconnect from supply tube. Remove the old pump seal with flathead screwdriver.
4. Install replacement part. Put seal in housing and connect pump outlet to water supply tube. Make sure outlet is aligned with holes and screw into position.
5. Put the dishwasher back together. Reinstall bearings and spray arm apparatus. Make sure it spins with friction or tension.
