Buzzing Electric Water Heater

(Someone from Electrical Appliances suggested I ask this question here.)

I just installed a brand new Whirlpool 50 Gal electric water heater (Model EE2H50RD045V). The electronic control assembly has an annoying semi-quiet electronic beeping sound, like a quiet alarm clock. When I called Whirlpool, they said they know if this, and it is because the electronics are picking up "static electricity" from the incoming power. They said to call the power company to see if I can get a "filter" on my power.

a) Does this sound right?
b) Has anyone ever had the power company "filter" their power?

It definitely won't be static electricity on your incoming power. There could other types of noise or spikes but it won't be static electricity.

Whirlpool really meant that perhaps there is some type of interference (wave of enegry such as radio, etc) causing it, or more likely there are bad harmonics on the line created by laser printers, microwaves, computers, etc. poor (not near Unity)Power factor could also affect it.

Is there any reason is should beep? Is there a consistency to the frequncy at which it beeps?

It beeps every 1/2 second - one on , one off. The water heater is in a condo with no other electronics per se on the entire service except a dishwasher, fridge and a microwave - and the beeps occur whether or not they running (The one-on, one-off makes me think I'm getting the run-around.)

Tell them you are going to take the unit out and return it. I hope you payed with a credit card because you can dispute the bill. There is no earthly reason for a water heater to even have a way to make a beep. Water below temp, heat it up. Water at temp, stop heating. This is not a place any fancy electronics should be required. Good old bi-metallic discs make the most reliable thermo switches.
