Water Not Getting Cold EnoughUpdated 6 days ago
If your water is cooling but not reaching your desired temperature, this means the chiller is working but something is slowing down its performance. This guide explains the most common causes and the steps you can take to improve cooling results.
1. Check Water Flow Strength
Weak water flow is the number one reason water struggles to reach colder temperatures.
Make sure
- the filter is clean
- the filter is not clogged
- water is circulating steadily
- hoses are fully connected
- hoses are not bent or kinked
Strong flow helps the chiller cool efficiently.
2. Clean or Replace the Filter
If the filter is dirty or worn, cooling performance drops immediately.
Replace or rinse the filter if
- the water is cloudy
- flow feels weak
- the filter looks discolored
- you have used the filter for several weeks
A fresh filter often restores cooling speed.
3. Keep the Lid Closed During Cooling
Leaving the lid open lets warm air constantly enter the water.
Always keep the tub covered while cooling to
- retain cold temperatures
- speed up cooling time
- support stable water performance
This is critical for outdoor setups.
4. Improve Ventilation Around the Chiller
The chiller releases warm air while it cools the water. If the unit cannot release this heat properly, cooling slows down.
Make sure
- vents are not blocked
- the chiller has open space on all sides
- the unit is not in a tight corner or cabinet
- dust is not clogging the vent screens
Good airflow helps the chiller reach colder temperatures faster.
5. Avoid Direct Sun Exposure
If your tub is outdoors, sunlight can warm the water faster than the chiller can cool it.
To improve cooling
- place the tub in a shaded area
- avoid full sun during warm hours
- use a canopy or sunshade if needed
Sun exposure is one of the biggest factors affecting cooling performance.
6. Move the Chiller to a Cooler Area
Cooling performance drops significantly when the chiller operates in hot environments.
For better cooling
- bring the chiller indoors
- avoid garages or sheds that get hot
- provide good airflow in the room
Cooler surroundings help the chiller cool more efficiently.
7. Check Ambient Temperature
If the surrounding temperature is very warm, the chiller may not reach the coldest settings.
Indoor setups provide more stable cooling. Outdoor setups may require
- more frequent lid usage
- shade
- stronger chiller models for larger tubs
8. Remove Air Bubbles from the Hoses
Air pockets inside the hoses reduce circulation.
Fix it by
- lifting the hoses gently
- adjusting their position
- making sure flow is smooth and continuous
Air bubbles often appear after refilling the tub.
9. Do Not Overfill the Tub
More water means longer cooling times.
Fill only to the recommended level for the fastest and most efficient cooling.
10. Give the Chiller Enough Time
Cooling large tubs takes time, especially from a warm starting temperature.
Factors that slow cooling
- warm tap water during refills
- large tub volume
- warm climate
- frequent lid opening
Plan ahead when you need the water cold at a specific time.
11. Restart the Chiller
A simple reset can sometimes improve performance.
Steps
- Turn off the chiller
- Unplug it
- Wait one to two minutes
- Plug it back in
- Turn it on again
Restarting clears minor control issues.

Contact our team if
- the chiller cools but never reaches the correct temperature
- the cooling performance has dropped over time
- the compressor does not sound like it is running
- you suspect a refrigerant or compressor issue
- the chiller stops cooling after long use
