Troubleshooting

My chiller won’t turn on

Try hitting the reset button on your GFCI adapter on the back of your chiller.
Try resetting your GFCI outlet.
Check the breaker in your home.

Water flow failure

Replace your filter. When the filter is clogged it will often trigger this failure.
Clean your hair strainer. Make sure that the hair strainer is not clogged.

My chiller keeps turning off

Make sure your reset button isn’t in a high traffic area, where it may be getting accidentally pushed.
Check your breaker. Make sure you are on a dedicated 15AMP breaker switch.
Check your electrical box for any moisture.
- If moisture is discovered in the electrical box if could be one of two things:
1. There is a breach in your electrical box somewhere. Check for damage or improper seal when it’s closed or cracks in the box.
2. The check valve on your ozone tubing has failed. This would allow a small amount of water to enter the electrical box and would trigger your GFCI to shut the system off. If you see water coming through the small ¼” clear tubing and entering your electrical box, turn off your unit and reach out to Harvia for a replacement part.

My chiller is leaking

It’s likely condensation. A small puddle of condensation is to be expected daily. It’s best to wipe it down once per day to avoid moisture buildup.
Test to see if the water level is getting lower in your plunge tub. Mark it and check again the next day. Also ensure that the leak is not coming from the plunge tub.
If your leak is significant, please reach out to Harvia customer service directly.
