The volume, hot and ambient icons of my Sterra 7 Tankless Water Purifier are sequentially blinkingUpdated 13 days ago

If your machine is showing this error, it means the power supply is either too high or too low.

This can happen when:

• The voltage is above 269V
• The voltage is below 165V

This is a built in safety feature. The machine will stop operating to protect its internal components.

Please follow the steps below.

Step 1: Switch off the machine

Turn off the machine using the main power switch.

Step 2: Try a different power socket

Plug the machine into a different wall socket.

If possible, avoid using an extension cord.

Step 3: Restart the machine

1. Leave the machine unplugged for about 10 minutes.

2. Plug it back in.

3. Switch it on.

Step 4: Wait for stabilisation and auto flushing

After turning it on, please wait at least 15 minutes.

During this time:

• The machine will stabilise the voltage.
• Auto flushing may start.
• The dispense button may show a breathing light.

Wait until all lights turn off. This means the process is completed.

This is normal.
