How Does Your Washing Machine Work? Basics and How to Tell When Something Is Wrong

Written for PRS Parts Inc.

Your washing machine is one of the hardest-working appliances in your home, running cycles that keep your clothes clean, fresh, and ready to wear. But like any machine, it relies on a sequence of functions and components working in harmony. At PRS Parts Inc., we help customers across Hawai‘i better understand their appliances and provide the parts they need to keep them running smoothly.

Here’s a simple breakdown of how your washing machine works and signs that something might be off.

🌀 The Basics: What Happens in a Wash Cycle

A typical wash cycle consists of the following stages:

1. Filling

Your washer fills with water to the appropriate level depending on the load size and selected cycle. Water temperature is controlled by mixing hot and cold water through inlet valves.

Key parts:

  • Water inlet valves

  • Temperature selector switch

  • Pressure switch (controls water level)

2. Agitation or Tumbling

Once filled, the washer begins agitating (top-loaders) or tumbling (front-loaders) to clean the clothes. The motor powers this movement through a transmission or belt drive.

Key parts:

  • Agitator or washplate

  • Drum (or tub)

  • Drive motor

  • Belt or clutch (in many models)

3. Draining

After the wash, the dirty water drains from the tub. This process prepares the washer for the rinse cycle.

Key parts:

  • Drain pump

  • Drain hose

  • Water level switch

4. Rinsing and Spinning

Fresh water enters for rinsing, and then the washer spins at high speed to extract as much water as possible before the cycle ends.

Key parts:

  • Spin motor or direct drive

  • Suspension rods or shock absorbers

  • Timer or control board

⚠️ Signs Something Might Be Wrong

Washing machines often give early warnings before a major failure. Here are some red flags:

  • Water not filling or draining properly? Could be a faulty inlet valve, clogged filter, or broken drain pump.

  • Noisy during spin? Worn-out suspension rods, a failing bearing, or a loose drum might be the cause.

  • Washer not spinning? This may be due to a damaged belt, faulty lid switch, or control board issue.

  • Water leaking? Check door gaskets, hoses, and the pump area for cracks or blockages.

  • Vibrating or walking? Uneven loads or worn shock absorbers can throw the balance off.

🛠️ Maintenance Tips to Keep It Running

  • Clean your washer filter and dispensers monthly.

  • Use only the recommended amount of HE detergent.

  • Level your machine to prevent wear on suspension parts.

  • Replace filters, hoses, and belts as needed—these are wear items.
