No Water coming out of water cooler

Here at The Water Cooler Company we receive a large number of calls from customers worried that there is a problem with their plumbed-in water cooler. In most cases these water cooler problems can be cleared up by following our simple troubleshooting instructions given below. For our rental and purchase customers we will of course go through this on the phone if needed – for the rest of you please enjoy the advice and tips for free.


Always, always check the power

Check that your water cooler is plugged in at the wall socket and that the mains power is switch is turned on (a surprisingly common cause of the cooler not working -). Check that the power cable at the back of the cooler is firmly pushed into its socket in the cooler and finally check that the switch (or both switches) on the back of the cooler is turned to the on position and illuminated. It is common for cleaners to use power socket at night and not replace it.

Check that the water block hasn’t tripped

water_cooler_water_blockThe first thing to look at is the water block -and check that it has not tripped. When the water cooler water block trips it stops any water reaching the water cooler. A picture of the water block is shown to the left. If the water block has the little red trip switch on it, check that this is pushed in.

If the water block does not have this trip switch then you will need to switch off the water supply to the cooler and then open up the top of the water block – when you look inside the water block you will see a pink button in the centre of the block. If this has popped out then simply depress the button to reset the water block. This will start the water supply again.

If your installation does not have a water block then it is essential to install one as soon as possible – these can be purchase through the water cooler installation kit section of our website.

Check the shut off valve

Locate the BLUE and WHITE shut off valve shown to the left. This is typically found at the back of the cooler. Check that the blue head of the valve is in line with the pipework as this lets water flow normally to the water cooler.

To turn off the mains-fed water supply to the cooler turn the blue head 90 degrees either clockwise or anticlockwise so that the blue head is at 90 degrees to the pipework.
