LG Washing Machine OE Error: Meaning, Causes & Safe Checks

OE Check carefully Safe checks first

Quick answer

LG OE means the water isn’t draining from the machine. LG says the likely causes are a kinked or clogged drain hose or a clogged drain pump filter. Unplug the machine, drain and clean the filter behind the small cover at the bottom front, and check the hose. If OE returns, contact LG.

What OE means on a LG washing machine

The washing machine can’t drain the water out.

Applies to: LG front-loading washing machines sold in the UK.

What you might notice

Likely causes

What you can safely check yourself

Stop and call a qualified engineer if:
  • The code or problem comes back after you’ve done the safe checks on this page.
  • The next step would mean removing a cover or panel, or working on the pump, valves, heater, motor, door lock or wiring. That is a job for a qualified engineer.
  • Water is leaking from inside the appliance or is near the plug or socket. Don’t touch the plug with wet hands or while standing in water. Switch off at the consumer unit instead.
  • The appliance is still under warranty. Contact the manufacturer first, because DIY work can affect your cover.

Work through these in order. Stop as soon as one of the signs above applies.

Clean the drain pump filter Take care

Before you start
  • Switch off and unplug the appliance at the wall socket before you touch hoses, filters or the back of the machine. Make sure your hands and the plug area are dry.
  • Water inside can be hot after a hot wash. Wait for it to cool before opening a filter.
  • Expect water to come out. Put towels and a shallow tray or baking dish down first.
  • Never force a locked door, a stuck filter cap or a seized part. Forcing it usually causes more damage.
Where the drain pump filter usually is Filter flap bottom front, one side Shallow tray + towels drain slowly, a bit at a time Filter cap turn anticlockwise slowly Some models have a small emergency drain hose here too
Where the drain pump filter usually is. Positions vary by model — check your manual.
  1. Find the small flap at the bottom front of the machine. Your manual shows the exact location and whether there is a small emergency drain hose.
  2. With towels and a tray in place, release the water slowly, using the emergency hose if there is one, or by turning the filter cap a little at a time. Expect more water than you think, and empty the tray as often as you need to.
  3. When the water has stopped, unscrew the filter fully and remove fluff, coins, hair grips and other debris. Rinse it under the tap.
  4. Look into the opening to check the pump blade can turn freely. If you can see it, manufacturers suggest turning it gently with a pencil, never with your fingers.
  5. Refit the filter firmly in its locked position and close the flap. Check for drips the next time the machine runs.

For this fault: LG: the filter cover is at the bottom left of the front (bottom right on some models). Drain the residual water hose into a bowl first, holding the hose while its cap is off, then turn the large filter cap anticlockwise.

Don’t reach in with fingers past the filter opening.

Don’t open the filter while the machine is running or the water is hot.

Check the drain hose position and for kinks Take care

Before you start
  • Switch off and unplug the appliance at the wall socket before you touch hoses, filters or the back of the machine. Make sure your hands and the plug area are dry.
  • The appliance is heavy. Pull it out slowly, ideally with help, and don’t strain the hoses or the cable.
Drain hose height and standpipe Outlet height min–max: see your manual Don’t push the hose in too far it can siphon or block No kinks or loops
Drain hose height and standpipe. Positions vary by model — check your manual.
  1. Check the drain hose behind the machine is not kinked, twisted or squashed against the wall.
  2. Check how far the hose goes into the standpipe or sink trap. Pushed in too far, it can siphon or block.
  3. Check the height of the hose outlet against your manual. Manufacturers give a minimum and maximum height above the floor or the machine base.
  4. If the hose has been extended, check the joint. Extensions narrow the flow and make blockages more likely.

Check the sink trap, spigot or standpipe isn’t blocked

  1. If the machine drains into the sink waste, run the sink tap and check the sink empties normally.
  2. Food debris often builds up where the machine’s drain hose joins the sink pipework. With the machine unplugged, you can undo that connection and clear it.
  3. If the machine was just installed, or the sink waste was replaced, check the blanking cap or bung has been removed from the spigot the hose connects to.
  4. If the sink itself drains slowly, the household drain is blocked rather than the machine. Clear it as you would any blocked sink.

When to call an engineer

If the checks above don’t clear OE, or any of the stop signs apply, contact LG or a qualified appliance engineer. Have the model and serial number from the rating label ready, and start with LG UK support.

Repair or replace?

Most OE cases are cleared by the safe checks above. If they don’t help, the remaining causes are parts an engineer has to diagnose. We don’t publish repair prices because they vary by area, part and model.

Questions people ask

How often should I clean the LG drain filter?

LG says regular cleaning is needed because laundry residue collects in the filter. Check your manual for the interval for your model.
