If you hear a buzzer warning coming from your spa control unit pump – this is because the filtering system has worked 150 hours accumulatively warning to remind you to clean the filter, at the same time, the light of the filtering function will flash.
To remedy this hold the filtering button for 5 seconds to turn off the buzzing. The filtering system will turn off, you can then press the button to activate the filtering system again.
We recommend you change your filters regularly to keep your water clean and free from impurities.
