Ex500isc displays error 20

First is machine spinning? machine only drains in spin mode.
If machine not spinning check lid is closed and check lid switch and plastic plunger that operates the switch located on the lid.
If machine is spinning then most likely a blockage on the drain hoses or pump. if there is water in the machine, lower the rear drain hose to low level, if water starts to flow out the hoses are not blocked, more likely a pump failure. To replace pump first drain all water from the machine with drain hose at low level.
Tilt machine back and remove the belt from below.
Remove the front panel.
To gain access and remove front panel insert a knife or thin blade approx. 4" in the from each side in between the front seam on the front panel, this will release the lid clips, lift and hinge back the lid panel, remove the two screws securing the front panel and remove.
Pump on right hand side at the back, disconnect main hose from pump by squeezing hose clip with pliers (may be a bit of water remaining). Unbolt pump and pull forward with the drain hose attached until it can be disconnected and pump fully removed.
Check pump for blockage and damage to impellor, replace/refit in reverse order.

You have a blockage in the drain hose or pump,
Try to drain all the water out before you remove the pump

Error Code 37,
37. (00100101) Phase 1 to 6 - Pump Blocked Error ( No change in the water
level)
While draining, the water level reading from the pressure sensor has not changed
for over 3 minutes. There are three likely reasons for this fault. One is that the
drain hose or the pressure switch hose has been squashed or kinked and the pump
out rate has been dramatically reduced. The second possibility is that the pump is
partially or fully blocked. The third is that the pump is not operating due to Motor
Controller module, wiring or pump failure. This fault could also appear if the
machine is pumping to an unusually high head of drain hose or into an extended
length of drain hose. The Fourth possibility is a diverter valve fault or blockage,
water level is not altering as the diverter is stuck in the recirculation mode, giving
the module the appearance the pump is not lowering the water level.
Primary Source: Pump System.
Action:
1) Check that the drain hose has not been kinked.
2) Check the length of the drain hose and try to reduce the length if excessively
long. A 1 metre extension hose of the same diameter fitted to the existing
drain hose is the maximum allowable length.
3) Check for open circuit windings in the pump. (Note: Pumps are fitted with a
thermal cut-out which will reset on cooling.)
4) If the bowl is empty of water, remove the pump from the pump housing and
check that it is not blocked. Also check the drain hose is not blocked.
5) If the bowl contains water, then service the pump from the top of the machine
by removing the top deck and inner bowl. Bail out the water, remove the
pump cap and hood and clear the restriction.
Secondary Source: Wiring.
Action:
1) Check the pump harness is connected correctly to the pump.
2) Check continuity of the pump harness.
Tertiary Source: Motor Controller module.
Action:
Activate the pump by operating the machine in spin mode. Check the pump
is rotating. If it is not operating, and Primary and Secondary checks have
been performed, then replace the Motor Controller module.
Note: Consider fitting Pump Hood Kit (WM013). If 5kg Smartdrive fit splash guard to
pump.

You are experiencing a water pump issue. . Check the drain hose for restrictions. Restriction, correct problem. No restriction, go to step (2). 2. Start the washer and check for 120VAC at the drain pump. Zero, replace the Main Control Board. 120VAC, remove the pump and check it for blockage. If blocked, remove the restriction, if not, replace the pump.

The LG error code OE simply means "the pump is blocked". Presumably the water isn't being emptied properly. As with all error codes it is possible that there is a cause other than the exact description in the error code explanation but basically this error means as far as the washing machine is concerned it thinks the water isn't pumping out. A pump, or filter blockage is the most common cause but it could be caused by other faults such as a faulty pump, or even a blockage in the drain hose or somewhere else in the system etc.

Check the drain hose for blockage. and see if the water filters is clogged. Specific instructions will vary based on your specific LG model. Most LG frontloaders have an access panel on the front for the water filter.

You have a blockage in the drain system.
Check the hose Check the filter Check where hose goes into waste water pipes.

Hi,
it is a Long Drain error


If the drain time exceeds 8 minutes, the water valves are turned off and "F/02" is flashed.
NOTE: After 4 minutes the "Sud" error will be displayed, then 4 minutes later the F02 error code will be displayed.

Press PAUSE/CANCEL twice to clear the display.

• Check the drain hose and make sure it is not plugged or kinked.
• Check the electrical connections at the pump and make sure the pump is running.
• Check the drain pump filter for foreign objects.
• If the above does not correct the problem, replace the pump.

Thank You

4 flashes indicates a drain failure. Could be obstruction in drain system-first check drainhose for kinks, check where drain hose attaches to wastepipe spigot for blockage. If OK blockage may be in pump- disconnect from power, remove bottom panels to access under machine. Drain pump located front left- remove plug from pump, then there is a plastic tag on top of pump you must push down, then drain pump will turn and come off (it comes off easily if tag pressed correctly, so don't force it!!)
If pump OK, fault will be with water indicator switch-sometimes get full of muck. Open dishwasher door, remove filters and clean out any water from base. Right in the bottom right hand side of sump you will see a round black grill- this is water level indicator switch. If it looks blocked up, advise replacing (you can try cleaning, but replacing is best). To replace, access from under machine-again, this switch turns and pulls out, but can be quite difficult due to it being located behind the heating tube.
So, check hoses and pump, then press and hold start button for 3 seconds- this clears fault and resets machine. Try another cycle-if OK, problem solved. Recommend expert assistence to replace water indicator switch.

E20 is an error code for drainage failure.



Check where the appliance drain hose connects to the house drains for a blockage.

If it's onto a spigot under the sink, take them off and check both for a blockage.

If these are ok then it's likely to be a blockage in the pump.



You'll need to drain the water out manually.

Put a shallow dish below the filter and slacken the filter.

Tighten it to stop the flow of water while you empty the dish.

Once empty, take the filter out, clean out the debris and ensure nothing is left jamming the pump.

Before refitting the filter, put the machine on drain or spin and listen at the filter housing to see if you can hear the pump running.

If you do, fit the filter and try the machine again.

Try cleaning out the pump, and main hose to sump. If problem persists replace pump.

The drain pump is jammed or one of the drain hoses has a blockage. Unplug the machine from the wall and remove the drain hose where it connects to the plumbing under the sink/tub. Check the spigot for any blockage. Next remove the drum to pump hose from the drain pump and inspect it for any obstruction. Feel inside the drain pump and try to turn the impellar by hand. The pump should turn freely. If it does not turn freely, it is seized and has to be replaced.
