Drain Pump

If the dishwasher is loud during operation, the drain pump might be defective or might have some debris in it. This is a common problem.

Circulation Pump

If the dishwasher is loud during operation, and the noise is a continuous drone similar in speed to the circulation pump sound, it's likely that the circulation pump motor bearings have failed. Once this happens the circulation pump will have to be replaced, the bearings are not repairable.

Drain Impeller

If the dishwasher is loud during operation, the drain impeller might be broken, or there might be debris in the pump. Generally, to gain access to the pump the top of the pump housing will have to be removed.

Pump and Motor Assembly

If the dishwasher is loud the motor bearings, drain impeller or wash impeller might have worn out. All three of these components are part of the pump and motor assembly. It may be possible to replace one of the impellers, but the motor bearings cannot be repaired. In that case the pump and motor assembly will need to be replaced.

Wash Impeller

The wash impeller is a small, plastic blade. The motor spins the impeller forcing water through the spray arms to clean the dishes. If one or more blades has broken off of the impeller the dishwasher is loud. The impeller can also scrape against the pump housing if it is damaged, warped or bent.

Water Inlet Valve

The water inlet valve is an electrically controlled water valve. When it is new, the water inlet valve is very quiet. Over time, the diaphragm inside the valve deteriorates and deforms. This deformation interacts with the water rushing in and can cause a loud vibration, buzzing, squealing or other noises. If the dishwasher is loud during the filling cycle, replacing the water inlet valve may solve the problem.

Dishwasher not draining


The drain hose and recirculation hoses can be responsible for leaks. The drain hose can cause the dishwasher to fail to drain properly. The recirculation hose can be responsible for problems with poor rinsing of dishes.

To access the drain hose remove the lower panel located beneath the door. The panel is usually held in place with two screws either above or below the panel. It may be necessary to first open the door to the dishwasher to reach the screws over the panel, then close the door to remove the panel.

The drain hose connects to the pump and runs to the sink drain (or to the air gap on top of the sink). The pump has a second hose that recirculates the water back into the dishwasher. The drain hose is roughly 1 1/2 inches in diameter. While inspecting the drain hose, check the recirculation hose as well for blockages.

When checking for leaks, feel the hoses where they connect to the pump, for wetness and check the ground right under the connections. If they are wet, it may be a loose or improperly mounted clamp, a damaged pump housing or a leak in the hose itself.

When checking for blockages, disconnect the drain hose from the pump, pinch the wire clamp with pliers and slide it up the hose. Place a shallow pan beneath the pump to catch any spillage. Remove the hose from the pump; wiggling the hose may help to loosen it.

Check the hose and nipple to the pump for any debris. The only way to be certain the drain hose is completely clear is to disconnect it from the sink and run water through (such as spraying a garden hose through it at full pressure). Disconnect the recirculation hose and check it in the same way.

Reconnect the hoses and replace the clamps. Replace the lower panel and restore electricity to the dishwasher.

Now, if the hoses were not blocked, move on to the pump.

Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher will not drain. Replace any broken pump components.

The final area of concern will be the Air gap.

If there is an air gap (located in the sink, near the faucet), check to see if it is clogged. Unscrew the top cap and see if there is anything blocking inside. Note: If there is no air gap installed, the dishwasher might not drain properly.

If the drain hose is clogged, the dishwasher will not drain. If there is an air gap installed, it is very common that a hose going from the air gap into the garbage disposer is clogged. Remove and clean the hose. Make sure to reattach the hose before starting the dishwasher.

Note: If you recently had a garbage disposer installed, it is common to overlook removing the drain plug.

That will conclude the necessary check points for this issue. check all areas carefully.

NOTE_ Worst case scenario will be a failed pump.

Dishwasher showwing LE error message


Hi Tanja

LE is motor error.

Empty water from inside the machine and try tripping the circuit breaker for a couple of minutes.

If that does no clear the error , then one of the following faults may have ocurred:

Wiring connection broken either bad connector on pump side or on timer control side, or faulty wiring harness.
The hose connected to impeller, or the impeller itself is blocked.
Motor or pump locked.
Faulty timer board.

Most likely the circulation pump. On this pump there is mounted a condensator. This will help the pump to get started. If this is broken, it wont circulate the water up to the sprayers.

LG LDF8812ST WONT DRAIN JUST INTERMITTENT BUZZ NOISE


Hi, there may be an obstruction in the pump housing that is causing the motor to freeze or, the impeller may be stripped and , jamming the pump. this will cause the hum you are hearing. the best way to inspect is to , extract the drain pump by, removing
the bottom drain filter housing or sump. manually
move the pump impeller to self it is moving freely. if the impeller is stripped, it will not be able to produce the draining surge necessary to pull the water out.

If the impeller is fine and, there are no obstructions visible, this will confirm pump failure.. replace the pump in this case


Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher would not drain. Replace any broken pump components.
