Osmolator Nano control board making noise

[heeman808]

Hi, I have a Osmolator Nano that began making a fast clicking/buzzing noise from the control board. It still is able to dispense water but the control board makes the buzzing noise every minute or so. I removed the board from the housing and there doesn't seem to be any damage. Help!!

How old is it? It could be the controller, either a defect or possibly water damage, it could be a failing pump.
