How do I clean and maintain Laundry Pump?

Lock the head and unscrew the pump from the bottle. Dip the nozzle in a cup of warm water and press 5 to 6 times to flush residue through the internal tube and nozzle. Shake off the excess, screw it back on and unlock. A weekly rinse keeps the nozzle clear and heads off drips and blockages.

✓ Three steps, once a week

1

Lock and remove. Lock the pump head down and unscrew it from the bottle.

2

Flush in warm water. Dip the tube and nozzle in a cup of warm water and press 5 to 6 times to flush the residue through.

3

Reinstall and unlock. Shake off the excess water, screw it back onto the bottle, and unlock the head ready for use.


What should I do and avoid for long pump life?

Three habits get Laundry Pump to its rated life of around 3,000 presses. Rinse the nozzle in warm water weekly, keep the bottle upright in a cool, dry spot, and lock the head when it's not in use or when you're travelling. Avoid bleach, alcohol, vinegar concentrates and strong solvents, which can damage the metal spring and plastic actuator inside. Warm water is all it needs.

✓ Good habits

Rinse the nozzle weekly in warm water. Keep the bottle upright in a cool, dry spot, and lock the head when it's not in use or when you're travelling. Regular care is what gets you to the around 3,000 presses the mechanism is rated for.

⚠ Avoid

Keep bleach, alcohol, vinegar concentrates and strong solvents away from the pump. They can damage the metal spring and plastic actuator inside and cut its life short. Don't force the head when you press it either. Warm water is all it needs.

No bleach No solvents No forcing the head Warm water only

What if the pump still isn't working?

If Laundry Pump isn't dispensing, prime it first by pressing several times. If it's still stuck, soak the nozzle in warm water for 5 minutes to dissolve the residue, then prime again. Most flow problems are residue rather than a faulty mechanism. If the pump leaks instead, or cleaning doesn't restore the flow, Laundry Pump Head is a direct-swap spare that fits every version and needs no tools.
