LG Dehumidifier Not Collecting Water

A detailed Los Angeles guide to LG dehumidifier not collecting water, including safe owner checks, common causes, model-specific diagnostic context, related error codes, and repair next steps.

If you are dealing with LG dehumidifier not collecting water, avoid turning one symptom into a one-part diagnosis. A dehumidifier can run without collecting much water when the room is already dry or cool, but no collection in a humid room can indicate airflow, sensor, compressor, or refrigeration problems. A model-aware process helps distinguish maintenance and installation conditions from sensor, motor, control, heating, cooling, or communication faults.

This article is written for an LG appliance repair website. It is not LG Electronics, does not represent an LG-owned service center, and does not claim manufacturer authorization. Use the exact owner documentation for your model when it gives model-specific instructions that differ from general guidance here.

Start by Defining the Symptom Precisely

Before troubleshooting LG dehumidifier not collecting water, write down what changed, when it happens, and whether the appliance finishes any part of its normal operation. A precise description is more useful than saying the unit is simply “broken.” Include the complete model number when accessible and photograph the display if a code appears.

Useful details include whether the problem is constant or intermittent, whether it starts after warm-up or after a particular stage, whether a reset changes anything, and whether another function still works normally. Those comparisons help separate a shared power/control problem from a fault limited to one subsystem.

Common Reasons This Happens

1. Room conditions

Low humidity or low room temperature can greatly reduce normal water collection. This possibility matters because the visible symptom can occur before the control has enough information to identify one failed part. On LG dehumidifiers, the exact test path depends on the model and on when the symptom appears.

2. Dirty filter or blocked airflow

Restricted airflow limits how much moist air reaches the cold evaporator. This possibility matters because the visible symptom can occur before the control has enough information to identify one failed part. On LG dehumidifiers, the exact test path depends on the model and on when the symptom appears.

3. Bucket or drain sensing

A mis-seated bucket, float, or drain setup can stop or alter operation. This possibility matters because the visible symptom can occur before the control has enough information to identify one failed part. On LG dehumidifiers, the exact test path depends on the model and on when the symptom appears.

4. Humidity sensor issue

Incorrect room-humidity feedback can make the unit cycle off prematurely. This possibility matters because the visible symptom can occur before the control has enough information to identify one failed part. On LG dehumidifiers, the exact test path depends on the model and on when the symptom appears.

5. Compressor/refrigeration problem

The fan may run while the coil never becomes cold enough to condense water. This possibility matters because the visible symptom can occur before the control has enough information to identify one failed part. On LG dehumidifiers, the exact test path depends on the model and on when the symptom appears.

6. Coil icing

Low airflow, cool ambient conditions, sensor faults, or refrigeration problems can cause frost rather than normal condensation. This possibility matters because the visible symptom can occur before the control has enough information to identify one failed part. On LG dehumidifiers, the exact test path depends on the model and on when the symptom appears.

Safe Checks You Can Do Before Service

These steps are limited to normal owner-level observations. If any step would require removing service panels, accessing live wiring, opening a gas system, working on a sealed refrigerant circuit, or bypassing a safety device, stop and move to professional diagnosis.

1. Check room humidity with a separate hygrometer if available.
2. Clean the user-serviceable air filter.
3. Confirm the bucket is seated correctly or the drain hose is routed as specified.
4. Feel for normal airflow and note whether the evaporator area ices visibly through accessible openings.
5. Record CH or other display codes and room conditions when they occur.

After the checks, run only one normal test when the appliance is safe to operate. If the same condition immediately returns, repeated resets usually add less information than preserving the code, sound, timing, and operating state for diagnosis.

What the Pattern Can Tell You

• Strong fan airflow with no cooling effect on a humid day differs from a low-humidity room producing little water.
• Ice formation can indicate an airflow, temperature, sensor, or refrigeration condition.
• A bucket-full indication with an empty bucket points toward sensing rather than moisture removal.
• Repeated compressor attempts or abnormal clicking should be professionally evaluated.

Related LG Error Codes to Watch For

A related code can narrow the investigation, but code meaning must stay inside the correct product family. Do not buy a part from the code alone. Depending on the exact model, useful codes or display conditions may include:

• CH — general monitored condition on applicable dehumidifiers; verify exact model. Confirm the exact definition for the model in the LG Error Code Library.
• CH01 — sensor-related condition on applicable models. Confirm the exact definition for the model in the LG Error Code Library.
• CH67 — fan-related condition on applicable models. Confirm the exact definition for the model in the LG Error Code Library.

When to Stop Troubleshooting

Stop using the unit for burning odor, repeated breaker trips, damaged power components, water entering electrical sections, or suspected refrigerant-system damage. Sealed-system and compressor testing require professional equipment.

Safety symptoms override convenience. If the unit is creating a water, fire, electrical, gas, high-voltage, or refrigerant hazard, leave it off until the condition can be evaluated safely.

What Professional Diagnosis Usually Looks Like

A dehumidifier diagnosis can compare room conditions with fan airflow, evaporator temperature, bucket or drain sensing, compressor operation, temperature/humidity sensor feedback, and control behavior. Collection problems can be environmental, airflow-related, sensor-related, or refrigeration-related.

A good service decision follows the measurements. The technician should be able to explain which operating result was abnormal, what tests isolated the cause, and why the proposed component or repair addresses that result. Replacing the most commonly discussed part without confirming the failure can waste time and leave the original problem unresolved.

Preparing for an LG Service Visit

• Photograph the model and serial label if it is accessible without moving a heavy built-in appliance.
• Save the exact error code or display message before resetting power.
• Write down when the problem occurs and which modes or cycles still work.
• Clear normal working space around the appliance without dismantling cabinetry or removing built-in equipment.
• Share relevant access information such as gates, elevators, parking limits, stacked installation, custom panels, or tight clearances.

Los Angeles Service Context

A dehumidifier’s water collection depends heavily on room temperature and humidity. Los Angeles coastal and inland conditions can differ, so record actual humidity and room conditions when judging performance.

The service address is also important because the site is being rebuilt around Los Angeles and Orange County local pages. Use the location page that matches the actual property rather than adding unrelated city names to the repair request.

Frequently Asked Questions

Should I reset the appliance when LG dehumidifier not collecting water?

One normal power reset can be reasonable when there is no safety issue and the owner instructions allow it. Record the code and symptom first. If the same problem returns, stop using repeated resets as a substitute for diagnosis.

Does the error code tell me which part to replace?

Usually not by itself. A code identifies a monitored condition or failed operating result. The model, symptom, wiring, installation, and measurements are needed to confirm the failed component.

Can an installation or maintenance issue cause the same symptom?

Yes. Water flow, drainage, venting, airflow, electrical supply, loading, door sealing, and other external conditions can produce symptoms that resemble an internal component failure.

What information should I include when requesting service?

Include the LG appliance type, complete model number when available, exact symptom, any displayed code, when the problem occurs, and the Los Angeles or Orange County service address. Add access details that may affect the visit.

Is this an official LG support article?

No. This is It uses LG product names only to identify the appliance brand and should be read together with the exact owner documentation for the model.
