Poor quality parts
When we received the sterilizer it worked, but emitted a whining sound when plugged in, so we only kept it plugged in when using it.  After 3 months of low (3 to 5 times a week) use the sterilizer has failed, with no power to the bulb.  It appears the ballest has failed.<br /><br />I replaced the ballast with a "Fulham Lighting WH2-120-C Workhorse 2 Versatile Fluorescent Lamp Ballast, 120V" and it now works properly and no longer makes any noise.
