Water Dispenser Not Cooling or Not Working
Most dispenser problems have a simple cause you can check in ten minutes. Try these steps before you call the brand's service centre.

Not cooling
- Check the green cold switch at the back is on.
- Wait 1 to 2 hours after switching on; the first cold tank takes time.
- Leave 10 cm between the back and the wall.
- Clean dust from the back grille (condenser) with a soft brush.
- If you moved the dispenser lying down, keep it upright for 4 hours before switching on.
- Low voltage stops the compressor; use a stabiliser if your voltage drops.
Not heating
Check the red hot switch at the back. Most heaters have an overheat cut-out that trips if the hot tank ran dry; switch off, make sure water flows from the hot tap, then switch on again.
Not dispensing water
- Top load: the bottle may be empty or have an air lock. Lift and refit the bottle.
- Bottom load: check the pipe is down in the bottle and the empty bottle light is off.
- Child lock: press or slide the lock on the hot tap first.
Leaking
A cracked bottle or a bottle neck that is not sealed is the usual cause. Try another bottle before you call for repair.
When to call the service centre
If the compressor runs but water stays warm, or the dispenser trips the breaker, stop using it and call the brand service centre. Keep your bill and warranty card ready.
