If steam or excessively hot water shoots out of faucets, or you hear boilding sounds inside the hot water heater, the appliance may not be shutting off at its set temperature. The job of the temperature- pressure (TP) relief valve is to release excessive pressure from steam buildup, but this valve may have been improperly installed, or it may be faulty. Either way, this condition can be dangerous, both because hot water and steam can scald people and because enough pressure could build up to rupture the water heater. Immediately turn down the water heater’s temperature setting and allow the water to cool.

I had also this problem before, same with buzzing sounds on my Amtrol Boilermate and all I had to do was to call the local dealer and they have got it fixed.

what is the water pressure on the cold side? You may need to install a pressure reducing valve at the water heater inlet to reduce inlet pressure and keep pop off valve from opening when not needed.

You need to flush your heater..or try to. This is going to be a minreal build you from what you are saying. I advise people to drain there heaters yearly in areas with water that has high minreal content. I hope it is not to late for you. The tools you will need are ; channel locks, and a flat head screw driver, water hose. There will be a faucet on the bottom of the heater. Connect the water hose to the end of the faucet, make sure your hose has a good rubber washer in it or you will have a mess from water leaking. You will want to disconnect the flex hoses from the top of the heater. The will break the vacum and allow the water to flow. You will want to run the hose out side. Try to keep it from going up hill. turn the faucet on. If you faucet does not have a handle and only has a notch you will need to use the screw driver. I hope this will work

What if you back the temp down to say 165 or so would that not keep the plastic from frying?
Also does that model not sit ambient until hot water is needed and is not "hot" 24/7/365 as you
stated? Just wondering.

then you must have a bad earth form the element . if you put voltage in a element that should be in water you blow it in seconds . if you want to get humidity leave it to air dry .

I'm not positive but insinkerator has been making these types of units for over a decade. You can buy them from amazon

Is there any water at all coming out? If not turn the cold water tap on the hot water tank on.

Is it gas or electric?

The use-and-care manual says that the 'product will eventually fail,' and to install a drain catch pan.The product has stainless steel tank with 3 year warranty. 1-800-558-5700.The manual does not show parts diagram, element, or anode rod. This indicates that operation is inside a sealed 1-piece unit not meant for repairs.High clorine content of water, and hard water, and water pressure over 80 psi will adversely affect any tank heater, and shorten lifespan causing probable leak.Turn off power:If you can remove cover from H770, then inspect 750 watt element for possible leaking. Then replace with new element of unknown type if element is leaking.If leaking is coming from the tank itself, then the unit cannot be repaired. This is true for all tank water heaters.http://waterheatertimer.org/Leaking-water-heater.htmlhttp://waterheatertimer.org/How-to-install-under-counter-water-heater.html If you need further help, I’m available over the phone at https://www.6ya.com/expert/gene_9f0ef4df2f9897e7

Check handles and make sure water is not coming out of stems and running under faucet. .

Don't know what type of handles you have plastic or metal remove handle .

Turn water on and remove handle and you should be able to see if water is coming from stem if it is it's probally a washer.

the low voltage may cause the unit to over heat when you dont have enough volts the amps go up .i have also seen units that are working fine dribble water due to expansion of water when heated

I am not sure they are available to non Hitachi service centres. https://documentation.hitachiaircon.com/glb/en/pac/rua-at3s
