LG Washing Machine: not washing bulky items, water temperature issue

Professional Repair Guide

What is this symptom?

If your LG washing machine struggles to wash bulky items or delivers incorrect water temperatures, you may experience poor cleaning results. This issue could stem from improper cycle settings, overloading the drum, or problems with the water temperature settings. Understanding the causes and solutions can help you restore your washer's efficiency.

Urgency: Medium

Important Tips for LG Models

  • LG washing machines use cycle selections to determine hot/cold mix, and water temp delivered depends on supply and cycle not just on machine set temp
  • Incorrect water temperature can be caused by faulty temperature sensors or inlet valve issues

Possible Causes

Incorrect cycle or wash settings not suitable for bulky items

How to Identify: Bulky items washed on a normal or inappropriate cycle instead of a Bulky/Large Items cycle

Part: User selections / cycle settings

Overloading leading to imbalance and poor washing performance

How to Identify: Washing machine capacity exceeded, items tightly packed or unbalanced within drum

Part: Drum load capacity

Water temperature settings misunderstood or water source setup issue

How to Identify: Selected cycle water temperature does not match delivered temp because cycle dictates hot/cold mix or water heater settings influence temp rather than washer alone

Part: Water inlet temperature control

Faulty temperature sensor or water inlet valve

How to Identify: Machine consistently delivers incorrect water temperature regardless of settings; possible error codes or inconsistent hot/cold blending

Part: Temperature sensor / inlet valve

DIY Solutions

Use correct cycle and avoid overloading

Easy 5-10 minutes
  1. Check washer manual for Bulky/Large Items or Bedding cycle
  2. Load only one bulky item or ensure items do not exceed washer capacity (drum ~80% full)
  3. Select Bulky or heavy-duty cycle and appropriate water temperature

Verify water heater temperature and supply connections

Moderate 10-20 minutes
Tools Needed: None or basic observation
  1. Ensure hot water supply is connected to washer’s hot inlet and cold to cold inlet
  2. Check home water heater setting is sufficiently warm (per manufacturer recommendations)
  3. Run a test with a normal load to observe delivered water temp
⚠️ Safety First: Avoid adjusting hot water too high to prevent scalding

Common Issues Reported by Users

  • Overloading the washing machine with bulky items like comforters can prevent proper washing and spinning.
  • Faulty water temperature sensor may cause the machine to not heat water properly, resulting in cold washes.
  • Blocked or kinked water inlet hoses can restrict water flow, affecting both washing performance and temperature.

User Suggested Solutions

  1. Reduce the load size by washing bulky items separately or with additional towels to balance the load.

  2. Check and replace the water temperature sensor if it is malfunctioning. Locate it near the water inlet valve and test with a multimeter.

  3. Inspect and clear any blockages in the water inlet hoses. Ensure hoses are not kinked and are free from debris.
