We have a D8991 that is making a beeping soundalarming I replaced the cartridges and water quality is great but the unit is still making the annoying alarming sound There are no error messages just the noise Would replacing the UV lamp with the ALMX13 bulb make the alarm go away Thank you
Answer
Yes it certainly sounds like a UV light alarm. With the unit running, slide the bub out a little and you should be able to see it lit. If it isnt, then that’s it for sure. I don’t believe that has an intensity monitor.
