Hello, thank you for your suggestion, on the basis of which the supplier contacted us and would like to respond below.
"Hello, the indicator light shows that the appliance is currently heating up. So, if you’re cleaning for a long time, the water will gradually heat up to ensure a sufficient supply of steam, which is why the indicator light flashes. If you have any queries, please do not hesitate to contact us at
[email protected]. Regards Team Sencor"
