Common Water Cooler Problems & DIY Fixes

Water Not Cold Enough (or Freezing)

Try a full reset first:

1. Dispense a few cups from both the hot and cold taps to drain the reservoirs slightly.
2. Switch off both the hot and cold switches on the cooler.
3. Unplug from the wall and leave unplugged for 24 hours.
4. Plug back in, switch both buttons on, and wait 5 hours before testing.

If the unit still won’t cool after a reset, check that the cooling coils at the back are clean and unobstructed. Dust buildup on the coils significantly reduces cooling efficiency — unplug the unit and wipe the coils with a dry cloth.

If freon (refrigerant) is the issue, you’ll need a licensed refrigeration technician — only certified professionals can legally handle refrigerants in Australia.

Strange Taste or Smell

Almost always caused by a dirty reservoir or an overdue sanitisation. Clean and sanitise the unit following our maintenance guide. If the taste persists after sanitising, replace the filter cartridge if your cooler has one. Browse our replacement cartridge range.

Leaking Water

Check the water bottle first — hairline cracks in the bottle are the most common cause of leaks. Inspect the bottle carefully before placing it on the cooler. Also check the taps — a dripping tap usually just needs tightening or a replacement tap washer. Browse our water cooler spare parts for replacement taps and O-rings.

Slow Water Flow from Taps

Usually caused by a blocked or exhausted filter cartridge, or mineral buildup in the tap. Replace the cartridge first. If flow is still slow, remove the tap and soak in warm water to dissolve mineral deposits.

Water Tastes Warm from the Cold Tap

If the cold water isn’t chilling, check the cooler isn’t in direct sunlight or against a heat source. The cooler needs adequate airflow around it — leave at least 10cm clearance on all sides. If placement isn’t the issue, try the reset procedure above.

Common Mistakes That Cause Damage

• Neglecting sanitisation — the reservoir should be sanitised every 3–6 months. Stagnant water breeds bacteria and mould.
• Using extension cords — always plug directly into a 3-prong wall outlet. Extension cords and power boards increase the risk of electrical faults.
• Placing in direct sunlight — UV and heat encourage bacterial growth and reduce cooling efficiency.
• Using cracked bottles — always inspect bottles for hairline cracks before placing on the cooler. A cracked bottle breaks the vacuum seal and causes overflow.

When to Call a Professional

Call a professional if:

• The unit won’t cool after a full reset and coil clean — likely a refrigerant issue requiring a licensed technician
• There are electrical faults, burning smells, or tripped circuit breakers
• The compressor is making unusual noises
• You need spare parts that require disassembly of internal components
