- To ensure adequate filtration – the filter acts like a sanitizer and a salt in keeping your hot tub water clean; therefore, tub filters need to be cleaned regularly and frequently to ensure that debris, dirt, and other contaminants are filtered off from the water.
- To avoid low flow – if the hot tub filter becomes dirty, the sensors will start sensing enough flow through the heater, so the sensors are turned off for safety. There is an error message highlighted on the screen such as “—,””DRY,””FLO.” Low flow can also cause slower heating and strain on the pump.
