The heater will not stay programmed. I have to re-input the time ect. Also, now when I turn the power on for the heater the LCD just blinks with SERVICE, but no codes (I have seen the code, for example, that appears when there is low pressure and the filter needs to be cleaned, but that it not this situation). Thank you. Jack
