My espring keeps beeping even though the cartridge is still showing 1 bar. this is the 3rd time i am having this problem. 1st time i brought to amway they said the mother board is fautly and did some repairing, after about 6 months, beeping again. this time they said the sensor is faulty and also did some changes. Now it is beeping again. It is very troublesome and annoying to have to keep bringing my set to amway esp since it is MCO now. Please update me on what will be done this time. I think its only fair to give me an espring replacement.
