-Turn off power first before working with electricity
- Suspect the heating element(s).They can be tested with a ohm meter. Replacing a heating element is not a difficult job.
-If you need to replace heating element(s),turn off water supply then drain water heater before replacing the element(s).
-BEFORE turning on the power to heater,turn on water suppy to heater
then turn on hot water at a sink or tub to purge air from water heater tank.If you turn on power first you will burn out new element(s)

Hi, can you say little more about its condition?

I had a similar problem and I had to find services to help me get rid of the problem. First I had the thermostat fixed but the problem was gone only for several days and I found services at
www.proservices.com
They have replaced the thermostat and it works fine now. I think you may be having the same problem. Try to get it fixed.
