How do I clean a washing machine before moving?

Preparing Your Washing Machine for Relocation

Cleaning a washing machine thoroughly before moving is a critical step often overlooked. It prevents the development of mould, mildew, and unpleasant odours during transit, especially if the machine is destined for storage or a new property where it won't be used immediately. A clean machine also helps meet the expectations of an end-of-tenancy clean.

Why Clean Before Moving?

• Prevent Mould and Mildew: Residual water and detergent can foster bacterial growth in a sealed, damp environment.
• Eliminate Odours: Mould and mildew produce strong, unpleasant smells that can permeate the moving lorry and the new property.
• Ensure Hygiene: A clean machine is ready for immediate use in the new home or for new tenants.
• Identify Issues: Cleaning can reveal minor issues, such as a clogged filter or worn seals, which can be addressed before the move.

Essential Cleaning Steps

Before beginning any cleaning, ensure the machine is unplugged from the mains electricity and that the water supply has been turned off. Information on when to disconnect utilities is available.

1. Drain Residual Water

Most washing machines retain some water in the drum, hoses, and filter. This must be drained to prevent leaks during transit. Locate the drain hose at the back of the machine, typically clipped to the main waste hose. Place a shallow tray or bucket below it, then unclip and lower the hose to drain. For machines without a separate drain hose, water will primarily be found in the pump filter.

2. Perform a Maintenance Wash

Run the washing machine on its hottest cycle (e.g., a 90°C or 95°C cotton wash) with nothing in the drum. This helps to flush out detergent build-up and kill bacteria. For an enhanced clean, add one of the following directly into the detergent drawer or drum:

• A dedicated washing machine cleaner tablet or liquid.
• Approximately 200ml of white vinegar.
• Two tablespoons of bicarbonate of soda.

A maintenance wash works best when the machine is empty, allowing the cleaning agent to circulate effectively.

3. Clean the Detergent Drawer

This often-overlooked area is prone to soap scum, mould, and mildew. Pull out the detergent drawer completely (most can be removed by pressing a release tab). Wash it thoroughly with warm, soapy water and a brush. Pay attention to any narrow compartments. Rinse and dry completely before reinserting it into the machine.

4. Clean the Door Seal (Gasket)

The rubber door seal is a prime spot for mould, mildew, and trapped debris. Pull back the folds of the rubber gasket and wipe the area with a damp cloth, optionally using a mild bleach solution or white vinegar diluted in water. A small brush can help reach tight spots. Rinse thoroughly with clean water afterwards and dry well.

5. Clean the Drain Pump Filter

This filter catches lint, small items, and debris, and can become a source of odour and blockages. Locate the access panel at the bottom front of the machine. Place a shallow tray or old towels underneath to catch any water that may escape. Slowly unscrew the filter, allowing any residual water to drain. Remove any debris, rinse the filter under running water, and clean the housing. Screw the filter back in tightly to prevent leaks.

6. Wipe Down the Exterior

Use a damp cloth and a mild all-purpose cleaner to wipe down the exterior of the washing machine, including the control panel and sides. This removes dust, dirt, and fingerprints, ensuring the appliance is clean and presentable.

7. Allow Thorough Drying and Ventilation

After cleaning, leave the washing machine door wide open for at least 24 to 48 hours. This allows air to circulate, thoroughly drying the interior, drum, and seals, which is crucial for preventing mould and mildew growth during transit or storage. It is also beneficial to leave the detergent drawer slightly ajar to allow it to air dry.

Once thoroughly dry, the washing machine is ready for disconnection and preparation for transit, including fitting transit bolts if applicable. Integrating this into a broader moving checklist can ensure no step is overlooked.
