Tank Water Heaters need to be flushed now and gain to get rid of MINERAL buildup. At the bottom is a water valve where you can attach a hose. Run the hose out doors and then open the valve to allow the water to flow freely.
That was easy. When water heats up, especially where the elements or gas flame are close to the heater bottom area, it may crackle or pop, but that is only expansion and contraction which is normal. Just watch to see if any water drips onto the floor which is a sign that the wall has been breached and the heater needs to be replaced.

try this, set the bottom therostat if it is electric , 10 degrees hoter than the top is set , if gas have no ideas

If the water heater is working fine than I would not worry about the function of the water heater. What the problem may be is that some of your WATER LINES HAVE MOVED, AS THEY WERE NOT SECURED PROPERLY. The sound you may have heard was the Copper or PVC(Plastic) lines just getting back comfortable. I Suggest checking that your water lines are secured about every 3 or 4 feet with the proper ancjhor....Metal for metal pipe, copper for copper pipe, etc. Sometime as in my house, pipes are run through a hole drilled through a stud or a piece of wood, usually when hot water is run through this pipe. You can here an expansion of the water line interacting with the pipe expanding, if the hole in the wood was not drilled big enough......Experience of remodeling a very old house.......Joe

If you are using a 3/8" copper line for your gas, get it replaced ASAP. It will fail. 1/2" Black Iron is required with natural gas. 50 gallons is a lot of water to heat. Look on the heater label for the recovery rate.

How big is your bathtub? Is your water heater set on the hottest setting? What is the temperature of the hot water at the tap?
Keep in mind that hot water can cause severe burns. Children and those with diminished mental capacity can be seriously harmed by hot water.
The "40 Gallon" rating on the water heater is usually the amount of hot water the unit can produce in one hour. So the tank, and the amount of immediately available hot water, might be smaller than 40 gallons.
My bathtub is 2 feet wide by 1 foot deep and 4 feet long. This is 8
cubic feet or almost 60 gallons. So a 40 gallons of water at 120 degrees, mixed
with 20 gallons of cold water (60 degrees), fills the tub with 100 degree
water. My January cold water is 42 degrees, so it will take 40 gallons at 129 degrees to fill the tub. If the tub is cold to start it will take even hotter water.
So the water heater might be just fine.
Possible solutions:
1. turn the temperature up on your water heater- or the temperature control could be malfunctioning and not getting the water hot enough.
2. insulate your hot water pipes so that the water loses less heat on the way to the tub.
3. bigger water heater.
4. smaller bathtub, or less full bathtub.

I had this problem back in April '09. I called the toll free customer support number in the manual. The lady said that that code indicated a communication problem between the panel and the main unit. She said they would send a new main circuit board and controller. In the meantime, the work around is to unplug the power, disconnect the panel and power back on. You will have hot water but no temperature adjustment. I had the new parts in about 2 days (shipped to Hawaii) and installed them. No problems for 9 months now. :-)
