Why is the Heavy light blinking which indicates a leakage error
I don’t believe that this is an installation error. I believe it is a manufacturing error. I had the product installed by a licensed plumber and there are no visible leaks anywhere.
As stated in the manual, when this occurs, please turn off the water supply and circuit breaker, then contact an authorized service center.
