Drain Pump and Drainage Repairs
An LG washer that will not drain needs the hose route, household drain, pump, and cycle conditions assessed. A drain warning alone is not enough to select a replacement pump.

Tell us what your LG washer does before the cycle fails: does it fill, drain, rotate, or try to balance the load? The symptom list covers documented front-load and top-load scenarios, with separate notes for washer/dryer combinations.
These are possible service scenarios, not confirmed diagnoses or a ranking of defect frequency. Use only the checks permitted by your model's owner manual.

Do not open the cabinet, bypass a lock, or probe electrical components. Internal repairs require qualified diagnosis; leaking or unsafe equipment should not be run repeatedly.
The work needed depends on your LG model and the cause of the problem. These are repair options we can assess, not a diagnosis from a symptom or error code alone. Model compatibility and parts availability must be confirmed.
An LG washer that will not drain needs the hose route, household drain, pump, and cycle conditions assessed. A drain warning alone is not enough to select a replacement pump.
We review LG fill behavior, water supply, and sensing before recommending parts. No fill, slow fill, and continued filling are treated as different problems.
The correct LG closure system depends on whether the machine is a front-loader or top-loader. We check the lock state and related conditions without bypassing the safety device.
The drive configuration is verified before repair advice is given. An LG rotation complaint does not justify assuming a belt fault, and top-load gear indications need their own interpretation.
We trace the water source and inspect the relevant seals and connections. LG front-load leak-protection reports are assessed separately from similarly named top-load drive codes.
Electronic, temperature, and combo-function reports are checked against the LG model. Features that are not fitted to the washer are not included in a parts recommendation.
Not sure which repair your LG washer needs? Include the full model number and describe what happens during the cycle. Our team will review the request and confirm service availability.
Request LG Washer ServiceLG front-load and top-load controls can give different meanings to the same code. AE is a key example in this reference. Use the family label and full model number; combo drying messages are marked separately.
Sources cover LG US front-load and top-load support plus the WM4000H*A / WM4080H*A manual. A top-load AE condition must not be interpreted using the front-load leak entry.
Service-reference entries may require technician diagnostics and may never appear on the normal display. No service-mode entry or component-testing instructions are provided here. Combo drying entries apply only to that subsystem.
More than one model-specific record matches this code. Compare the family and model notes before interpreting it.

Washer/dryer combination only. This is not a standalone washer fault.
No matching record is shown. Reset the filters, check the exact spelling, or send us the model number and a display photo. This reference is not a complete catalog of every control revision.
Model check first: the same code may have more than one meaning across control families. Normal lock, cleaning, update, or cooldown messages are not automatically faults. Do not order parts from a code alone.
Arrange LG washer diagnosis when the same fault returns or a normal load still cannot complete a cycle. A photo of the code and the full model number help distinguish front-load, top-load, and combo conditions.
