What can you do if there is no water coming out of your cooler. We’ve created this hand guide to show you some of the most likely causes for this.
Troubleshooting 1:
If there is no water coming out of either of the taps on your cooler it’s important to check it has not been isolated near at the machine. If you rent a machine, most suppliers will fit this below part that allows an engineer to stop the water getting to a machine without tracing all the way back to the mains supply.


If the part is like image 1 with the tap in line with the tube, water can get to the machine.
If it looks like image 2 – no water can travel beyond this part. You will simply need to turn it so it is horizontal and this should resolve the issue.
Troubleshooting 2:
Some coolers can only dispense if they are plugged into the mains. It’s always good practice to ensure the lead at the rear is pushed firmly into the back of the cooler, and that it is plugged into a mains electrical socket. Also please check the socket is switched on, as these can be switched off by accident.
Troubleshooting 3:
A mains fed water cooler has 2 floats inside its tank. These allow mains water to enter the tank when water is dispensed from the taps.
If one of the floats has got stuck or “tripped” due to a pressure surge, no more water will be able to get from the mains to the tank. To reset your cooler, you can unscrew the lid and on the top of the reservoir there will be a reset button. Simply press this and you should hear water starting to flow back into the tank.
Troubleshooting 4:
Mains fed coolers quite often use a part next to the mains water connection to control flow. This is called a water blocker and looks like this.

These can also trip (like the floats) if a large volume of water has been dispensed from the cooler. Most will have a red trigger on them that allows you to reset this part without disconnecting.
Troubleshooting 5:
Finally if none of the above works, your coolers compressor may well be working a little bit too hard.
This can happen in hot stuffy rooms, or in the middle of summer when the outside temperature is far higher than normal.
If this is the case the cooler can develop an ice-ring inside of its tanks. It looks just like giant Polo! Overtime this can build up and block the tap outlets inside the tank and stop the water from flowing. If you suspect this is the case, turn off the electrical supply to the cooler overnight.
If you can dispense water in the morning you will need to turn down the thermostat at the back of your machine.
