AO SMITH WATER PURIFIER RO SCPA BLINKING ERROR RESET | REVIEW

AO SMITH WATER PURIFIER RO SCPA BLINKING ERROR RESET. DO THIS ONLY FOR EMERGENCY.. RECOMMENDED TO CHANGE FILTERS ON SHOWING ERRORS..
Review..
Not recommended, Do not buy..
every year once this error will blink by default , whatever you use (heavy or medium), this error will blink automatically every year correctly.
so thier filers are not sensor based to automatically find the dust and blink the error.
AMC = Rs.4500
Each filter replace 1500 +
service charge 450
SO MAINTENANCE COST IS TOOOOO HIGH.
