Description

Product Overview

The LG Electronics 4738ER1002A washer tub‑to‑pump hose is engineered with a high‑grade plastic construction that balances flexibility and strength. The integrated bellows section absorbs vibration and accommodates movement during the wash and spin cycles, reducing the risk of wear and tear on the hose itself. Measuring 13 inches in length with a nominal wall thickness of 1 mm, the hose provides a precise fit for a range of LG front‑load and top‑load washing machines. Its black finish blends seamlessly with most appliance interiors, while the reinforced ends feature secure connections that prevent leaks and ensure a tight seal. Designed for durability, the hose can withstand temperature fluctuations and exposure to detergent residues without degrading, making it a reliable replacement part for long‑term appliance maintenance.

Beyond its core material advantages, the hose incorporates a cleanout port that allows users to flush out debris and prevent blockages. This feature is especially valuable in households with high‑efficiency detergents or where lint buildup can impede water flow. The part is certified by LG and complies with industry standards for dishwasher and washing machine replacement hoses, ensuring compatibility and safety. With a lightweight design of just 5.6 ounces, the hose is easy to handle during installation, reducing the physical effort required for service technicians and DIY enthusiasts alike.

Usage

Designed for everyday household laundry cycles, this tub‑to‑pump hose excels in environments where consistent water evacuation is critical. Whether you are running a quick rinse or a heavy‑load wash, the hose’s flexible bellows adapt to the pump’s motion, maintaining a steady flow of water from the tub to the pump. It is particularly suited for modern LG models that feature high‑speed spin functions, as the hose can absorb the rapid pressure changes without cracking or bursting.

Homeowners looking to replace a worn or leaking hose will find this part straightforward to install. The hose is compatible with most LG washer models that use the 4738ER1002A part number, and it can also serve as a universal replacement for similar LG appliances that share the same connection dimensions. For professional service providers, the hose’s quick‑connect fittings reduce service time, allowing for faster turnaround on repair orders and minimizing appliance downtime for customers.

Installation Guide

Before beginning the replacement, disconnect the power to the washing machine and turn off the water supply to avoid accidental leaks. Locate the existing tub‑to‑pump hose, typically found at the rear of the washer where the tub outlet meets the pump inlet. Detach the old hose by loosening the clamps or unscrewing the connectors, taking note of the orientation for the new hose.

Take the new LG 4738ER1002A hose and align the bellows section away from the pump to allow free movement. Insert the hose into the tub outlet, ensuring the connector sits fully inside the fitting. Secure the connection with the provided clamp or screw mechanism, tightening it until it is snug but not over‑compressed. Repeat the process on the pump side, making sure the hose runs without sharp bends that could impede water flow. Once both ends are firmly attached, re‑connect the water supply, restore power, and run a short test cycle to verify that water drains correctly and no leaks are present.

Maintenance & Care

Regular maintenance of the tub‑to‑pump hose can extend its service life and maintain optimal washing performance. After each wash cycle, inspect the hose for signs of wear, such as cracks, discoloration, or bulging at the bellows. Clean the cleanout port periodically by flushing it with warm water to remove any lint or detergent residue that may accumulate over time.

If you notice reduced drainage speed or unusual noises from the pump, check the hose for blockages or kinks. In most cases, gently straightening the hose or using the cleanout port to clear debris resolves the issue. For households that use high‑efficiency detergents, consider performing a monthly rinse of the hose with a mild vinegar solution to prevent mineral buildup. Should the hose show any damage, replace it promptly to avoid water leakage that could damage surrounding components.

Compatibility

The 4738ER1002A hose is compatible with a wide range of LG washing machines, including both front‑load and top‑load models that share the same connection specifications. It is also suitable for certain LG dishwasher models that utilize a similar tub‑to‑pump configuration, making it a versatile spare part for multiple appliance types. Before purchasing, verify the model number on your appliance’s service tag to ensure the part number matches 4738ER1002A. This verification helps guarantee a seamless fit and eliminates the need for modifications or adapters.

The hose’s dimensions and connector types have remained consistent across several generations of LG washers, making it a reliable replacement for many legacy models.

How do I know if the hose needs to be replaced?

Look for visible signs of wear such as cracks, brittleness, or discoloration. If you notice water pooling around the hose connections, reduced drainage speed, or unusual noises from the pump, these are indicators that the hose may be compromised and should be replaced promptly to avoid further damage.

What warranty does the hose come with?

The hose is covered by a standard manufacturer warranty that protects against defects in material and workmanship for a period of 12 months from the date of purchase. If you encounter any issues within this timeframe, contact our support team for a replacement or refund.
