What does LG Dishwasher Not Drying - Causes & Fix mean?

Empty or low rinse aid is the most common cause. Refill the rinse aid dispenser and turn the setting up to improve drying performance.

How do I fix LG Dishwasher Not Drying - Causes & Fix?

Follow the step-by-step diagnosis below. The most likely fix is identified by checking power, sensor resistance, and control-board signals in order — using a multimeter and the part numbers documented in the parts reference table.

Can I keep running the equipment with this fault active?

Generally no. Faults on Appliance units are emitted when a sensor, safety, or control circuit is outside its operating envelope. Running through an active fault risks compressor, heater, or control-board damage. Diagnose and clear the fault first.

What part is most commonly replaced for LG Dishwasher Not Drying - Causes & Fix?

The most frequently replaced parts for LG Dishwasher Not Drying - Causes & Fix are listed in the Parts Reference section of this guide with OEM part numbers and typical price ranges. Check the table for direct replacements.

Is LG Dishwasher Not Drying - Causes & Fix a DIY repair or do I need a technician?

Sensor swaps, fan motor replacements, and condenser cleaning are typical DIY-level repairs. Anything involving refrigerant, gas, or high-voltage (>240V) work requires a licensed technician for both safety and code-compliance reasons.

LG Dishwasher Not Drying - Causes & Fix

LG Dishwasher Not Drying — What’s Happening

An LG dishwasher that is not drying is a performance symptom, not a fault code. LG’s official support guidance treats this as a drying-condition issue where dishes remain wet after the cycle completes. LG notes that wet tub walls with dry dishes can actually be a normal condition because condensation remains inside the tub while the load itself dries properly.

Poor drying performance is often improved by using rinse aid, selecting drying-boost options like Extra Dry, Night Dry, or Sanitary Rinse, and allowing proper end-of-cycle venting. If drying is poor and there is no airflow near the vent during the final dry portion of the cycle, LG indicates the unit needs service.

Most Likely Causes

Rinse aid empty or insufficient LG says rinse aid is necessary for optimal drying and recommends refilling the dispenser and adjusting the setting upward if drying remains poor.
Drying options not selected LG specifically calls out Extra Dry, Night Dry, and Sanitary Rinse as performance-improving options that should be used when available on your model.
Door left closed after cycle LG says opening the door at the end of the cycle helps remaining humidity evaporate and prevents re-condensation on dishes and tub walls.
No airflow at vent during dry phase LG states that if no airflow is felt at the lower-left door area during the last 30 minutes of drying, the unit requires service.
Failed heating element or heater circuit Repair guidance identifies the heating element and circulation-pump-heater system as a common failure path when the unit does not generate enough heat for drying.
Faulty vent fan motor or vent assembly Independent repair sources point to vent fan issues as a main cause of poor drying when airflow is blocked or the fan motor fails.
Overloading or plastic-heavy loads Trapped water and poor airflow from incorrect loading can mimic a failed dryer system, especially with plastics that do not retain heat.

How to Diagnose and Fix

Verify whether the complaint is truly poor drying or normal tub condensation, since LG says wet tub walls alone do not prove a fault.
Check the rinse aid reservoir and refill it if empty, then increase the dispenser dial setting to a higher level if drying does not improve.
Confirm that drying-related options were selected during the cycle, including Extra Dry, Night Dry, or Sanitary Rinse depending on your model.
Run a full cycle and feel for airflow at the vent area near the bottom left side of the door during the last 30 minutes of the dry phase.
If no airflow is present at the vent during drying, the unit needs service and you should proceed to component-level checks of the heating and venting system.
Inspect loading practices to verify dishes are not overloaded and plastics are positioned to allow water drainage and proper airflow.
Test the heating element for continuity and resistance if accessible (non-manufacturer repair guidance suggests about 12 ohms as a field reference, not an LG spec).
Check the vent fan motor for power and operation during the dry cycle (non-manufacturer repair guidance suggests around 120 V AC when energized, not an LG spec).

When to Call a Pro

Call a pro if you confirm no airflow at the vent during the last 30 minutes of drying, if the heating element or vent fan motor tests faulty, or if rinse aid and cycle-option changes do not improve performance. Electrical testing of the heater circuit, vent fan, and control board connections requires proper meter work and safe access to live components. LG does not publish resistance or voltage specs for the drying system in consumer guidance, so component-level diagnosis relies on field experience and proper part testing.
