LG Washing Machine Won't Drain

LG Medium fix Updated 2 August 2026
Quick Fix

Check the drain hose and clean the user-accessible pump filter exactly as the model manual specifies after water has cooled (about 5–30 minutes).

Fault description

The LG washer cannot drain water from the drum.

Check the drain hose and clean the user-accessible pump filter exactly as the model manual specifies after water has cooled. Open no panels, measure no sensors or wiring and do not order a part from the code or symptom alone.

Causes

  • Kinked or blocked drain hose — Restricted flow prevents draining.
  • Clogged pump filter — Lint or small objects can obstruct the accessible filter.
  • Excessive suds — Overdosing may create air pockets and interfere with pumping.
  • Internal pump or drainage fault — A persistent fault after external checks requires service.

Step-by-Step Fix

  1. 1

    Stop safely

    Pause the programme, wait for the drum to stop and do not force the door.

  2. 2

    Unplug for checks

    Disconnect with dry hands before filter, hose or other user-accessible checks.

  3. 3

    Take the correct action

    Check the drain hose and clean the user-accessible pump filter exactly as the model manual specifies after water has cooled.

  4. 4

    Test once

    Make one test after correcting an external cause and only without leakage, smell, heat, smoke or electrical damage.

  5. 5

    Arrange LG service

    Request authorised service if the fault returns or an internal sensor, pump, motor or control is suspected.

When to call a service technician

Arrange authorised LG service if the drain fault remains after safe external checks. Temperature sensors, internal pumps, motors and electronics are not user repairs.

Unplug immediately for leakage near electricity, burning smell, smoke, sparks, abnormal heat or tripped protection.

Prevention

Follow load limits, mix large and small items, empty pockets, dose correctly and keep the drain hose and user-accessible filter clean as the manual specifies.

Keep the washer level; internal sensor, pump and electronics faults cannot be prevented through dismantling.

Frequently Asked Questions

Can I keep using a Bosch washer showing —?

Check the drain hose and clean the user-accessible pump filter exactly as the model manual specifies after water has cooled. Do not run another cycle until Bosch guidance or service confirms it is safe.

Can I reset — by switching the washer off?

Switching off is a safety step, not proof that the fault is repaired. If the code returns or Bosch classifies it as service-only, do not repeatedly reset the washer.

Does — identify a part to replace?

No. The code identifies a system or condition, but Bosch service should diagnose the exact cause before any part is ordered.

Why should I provide the E-Nr?

Bosch model families and markets can use different hardware and service procedures. The E-Nr identifies the correct appliance documentation.

May I test the sensor myself?

No. Do not remove panels or measure internal wiring, sensors or electronics. Bosch directs these codes to customer service.
