How do I unlock Dish Pump?

Dish Pump ships sealed for transit so it does not leak in the box. To unlock it, hold the bottle firmly with one hand and grip the pump head with the other, then twist the two parts apart in opposite directions until the head releases and lifts up. If the head feels like it spins without lifting, keep twisting and give it a firm upward pull. Make sure you are twisting the pump head itself, not the whole bottle.

Three moves

1

Hold the bottle firmly with one hand, gripping the neck for leverage.

2

With your other hand, grip the wider collar just below the pump head.

3

Twist the two parts apart in opposite directions while pulling gently upward, until the head lifts.

If it spins without lifting

Keep twisting and give it a firmer upward pull. Check you are twisting the pump head itself, not the whole bottle. This is the transit seal releasing, not a fault.

Firmer pull Twist the head only

It is sealed on purpose

The seal stops Dishwashing Liquid leaking in transit. Every new bottle needs this one-off unlock before first use.

How do I prime it on first use?

Once the pump head is raised, press it down a few times until liquid begins dispensing. The first few presses may come out dry while the dispenser draws Dishwashing Liquid up the straw from the bottom of the bottle. If the pump is open but still not dispensing, keep pressing to prime it fully. Once primed, each press delivers about 4 ml.
