How To Clean a Washing Machine

A step-by-step guide to removing odours, mould and residue — and keeping your machine running efficiently.

⚠️ How often should you clean it? — Run a hot maintenance wash at least once a month if you regularly use low-temperature programmes. Clean the door seal and pump filter every one to three months.

Step-By-Step Cleaning Guide

🧼

Clean the Detergent Drawer

Remove the drawer by pressing the release tab and pulling it out. Rinse under warm running water, scrubbing away detergent and conditioner residue with a soft brush. Wipe the drawer housing with a damp cloth and allow to dry fully before replacing.

🔵

Clean the Door Seal

Pull back the folds of the rubber door seal and wipe thoroughly with a damp cloth. For stubborn mould, apply diluted white vinegar, leave for a few minutes, then wipe and rinse. Dry the seal thoroughly after cleaning to prevent regrowth.

🌡️

Run a Hot Maintenance Wash

Place a washing machine cleaner tablet in the drum, or add 250ml of white vinegar directly. Select the hottest programme available — ideally 90°C — and run the machine empty. This kills bacteria, breaks down detergent residue and removes limescale from internal components.

🔧

Clean the Pump Filter

The pump filter is behind a small panel at the bottom front of the machine. Place towels beneath it before opening — water will drain out. Twist the filter cap anticlockwise to remove, clear any fluff, coins or debris, and rinse under running water. Refit by twisting clockwise and ensure it is tightly secured to prevent leaks.

Wipe Down the Exterior

Wipe the outside of the machine, door glass, and control panel with a damp cloth. Avoid abrasive cleaners on the control panel as these can damage the finish.

Leave the Door Ajar After Every Wash

After every wash cycle, leave the machine door slightly open to allow the drum to air out and dry. This is the single most effective way to prevent mould and musty odours from developing inside the seal and drum.

🔧 When to call a professional — If smells or performance issues persist after a thorough clean, there may be a blockage deeper in the machine’s pipework or drainage system. A qualified engineer can also check the heating element for limescale damage. View all washing machine error codes →
