I bought this product just 2 years back and SFF indicator for GKK1 started blinking as usual.
Ordered the new one but after installing, the reset button not working.
Technician said Control circuit has gone bad and even though all display is working still chipset will need replacement.
The cost would come as 5500 which is rediculous considering already spent 20000 hardly 2years back. It would have been more cost effective to have bisleri water supplied for 20000+ 6 time kit changes in 2 years(appx 10-15k). Totally would have spent almost 30000. Consider how many 20Ltr bisleri I could have bought for this much of money.
FYI Warranty is given only for 1 year by company.
