Chiller Making Unusual Noise
Your chiller is not silent. It contains a compressor, a pump, and a fan, all of which produce some sound during normal operation. Before troubleshooting, it helps to understand what normal sounds like.
What is normal. The chiller operates at 52 decibels, roughly the same volume as a quiet conversation or a modern refrigerator. You will hear a low hum from the compressor when it is running, a gentle whir from the pump circulating water, and occasional clicks as the compressor cycles on and off to maintain temperature. These are all normal. The compressor does not run all the time. It switches off when the target temperature is reached and kicks back in when the water warms. You will notice periods of near silence followed by the hum starting up again. This is how the system is designed to work.
If the pump sounds louder than usual
The pump is the component most customers notice. It runs continuously while the chiller is plugged in, circulating water between the bath and the chiller. If it sounds louder than you remember, check the following.
1. Check the filter.
A clogged filter forces the pump to work harder to pull water through the system. This increases the noise. Open the rear access panel, remove the filter using the black filter key, and rinse it thoroughly under a tap. If it is heavily blocked, swap it for a spare. This is the most common cause of increased pump noise.
2. Check the water level.
If the water level in the bath has dropped too low, the pump intake can become partially exposed. When the pump draws in a mix of air and water, it produces a louder, more uneven sound. Top up the bath with fresh water until the level is 15 to 20cm below the rim.
3. Check that nothing is touching the chiller.
If the chiller is resting against a wall, fence, furniture, or the ice bath itself, vibration from the pump can transfer to that surface and amplify the sound. Pull the chiller a few centimetres away from anything it is touching.
4. Check the surface.
The chiller should sit on a flat, stable surface with all four corners of the frame in even contact. An uneven surface can cause the unit to vibrate or rock slightly when the pump is running. If the surface is uneven, adjust the position or place a thin mat underneath to level it out.
5. Check the teak cover.
If the teak cover is not seated properly on the chiller frame, it can rattle or buzz when the pump is running. Lift the cover off, check that nothing has fallen between the cover and the frame, and place it back so it sits flush and level.
If you hear grinding, scraping, or loud clicking
Power off the chiller immediately. A grinding, scraping, or loud repetitive clicking sound from the compressor is not normal and may indicate an internal fault. Unplug the chiller from the power socket and contact our support team straight away. Do not continue running the chiller as this could cause further damage. A short video recording of the noise before you power off is extremely helpful for diagnosis.
If the noise is coming from the fan
6. Check for debris around the fan.
Leaves, dust, insects, or small objects can collect around the fan grille, particularly on outdoor installations. If something is caught near the fan, it can cause a buzzing, ticking, or rattling sound. Clear any debris from the fan side of the chiller and check if the noise stops.
Still concerned about a noise? Send us a short video recording. Hold your phone near the chiller for 10 to 15 seconds so we can hear what you are hearing. This is the fastest way for us to tell you whether it is normal operation or something that needs attention.
