Model SAPLUM035One week after the warranty expired, the condenser broke down and there was no cold water. The safety mechanism for the hot water also spoil after one and a half year. Call the salesperson, she say other users do not face such issue, and buy thing must see luck.(Update) I would like to thank Syed & Zal from Pere Ocean who rendered assistance. A brand new model was exchanged for my faulty one, with a purchase of a one year warranty for $300 w/gst.
