Hello there, My UV lamps do not light up. It mentions using Optimizer, which is not a product of HP. How is this possible? Are there fake Optimizers? I always buy it from the authorized dealer (10 liters). Also Optimizer head marked. And the lamps do not light up. They said it will burn after spending 30 liters. I spent more than 100 liters but it didn't burn. How long will this take? I think this was due to a pressure sensor error. How will it fix?
