Understanding Aquaguard Light Indicators
Before I explain the different Aquaguard light indicators, let’s first go over some key points.
1. Power ON Time
When you turn on your Aquaguard, you’ll see three lights (red, blue, and green) blink in sequence. Here’s how it works:
- First, the red light blinks.
- Then, the blue light blinks.
- Finally, the green light stays on for five seconds, which means your purifier is ready to use.
2. Tank Filling
If your purifier is filling the water tank, the blue light will blink every 0.5 seconds. Once the tank is full, the light will stay on.
3. UV LED Fault
If there’s a problem with the UV light (which helps purify the water), the red light will stay on.
4. SV/Pump Fault
If there’s an issue with the solenoid valve or pump (the parts that allow water to enter the purifier), the red light will blink every 0.5 seconds.
5. Dry Run Sensor (DRS)
If the water tank is empty or almost empty, the purple light will turn on. This is a reminder to refill the tank.
6. Electronic Authentication Error
Aquaguard uses special filters with electronic authentication to make sure you’re using the original ones. If the filter needs to be replaced, the red light will blink every 0.25 seconds.
