How do I clean and maintain Laundry Pump?

Give the nozzle a warm water rinse once a week. Lock the pump head down and unscrew it from the bottle. Dip the dip tube and nozzle into a cup of warm water and press 5 to 6 times to flush detergent residue through the internal tube and out of the nozzle. Shake off the excess water, screw the head back onto the bottle and unlock it ready for use. A weekly rinse keeps the nozzle clear and stops drips and blockages building up over time.

✓ Three steps, once a week

1

Lock and remove. Press the pump head down into its locked position and unscrew it from the bottle.

2

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

3

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

What helps the pump last, and what should I avoid?

Three habits help Laundry Pump reach its rated life of around 3,000 presses. Rinse the nozzle in warm water weekly. Keep the bottle upright in a cool, dry place. Lock the head down when the pump is not in use, especially when travelling. Avoid bleach, alcohol, vinegar concentrates and strong solvents anywhere on the pump, because the actuator holds an internal metal spring and a plastic mechanism that harsh chemicals can damage. Do not force the head when pressing either. Warm water is all it needs.

✓ Good habits

Rinse the nozzle in warm water weekly. Keep the bottle upright in a cool, dry place, and lock the head down when the pump is not in use or when you are 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. The actuator holds an internal metal spring and a plastic mechanism that harsh chemicals can damage. Do not force the head when pressing either. Warm water is all it needs.

No bleach No solvents No excessive force Warm water only

What if the pump still is not dispensing?

Start by priming it, because most flow problems are a dry tube rather than a fault. Press the head several times and see whether flow returns. If it is still slow or stuck, soak the nozzle in warm water for around 5 minutes to soften any detergent residue, then prime again. Most flow issues come from residue rather than a faulty mechanism. If cleaning does not restore normal flow, or the pump is leaking rather than blocked, get in touch with our team and we will sort it out for you.
