When u turn on the hot water at the faucet, do u turn on just the hot? Because my heater turns off the moment I turn on the cold water. I think it must have something to do with the amount of pressure the water is coming in and out of the water heater. It has to be at a minimal pressure or the heater will not operate properly. When I turn on my cold water to mix with the hot, I guess it reduces how much pressure I'm pulling from the heater so it turns off. Although when I'm taking a shower, my shower head allows for a higher gpm (gallon per minute), so I can have both the hot and cold water running at the same time in my shower only.

If your problem is occurring even with the temperature low AND your tank is older, it is possible that the heating coils within the heater are deteriorating. This exposed "hot spots" that boil the water even if your temperature is low. Or...the thermostat is broken and on "high". This has finally happened to mine and I get noise and sputtering even at the lowest setting. Time for a new tank for me. Mine lasted 10 years.

what part of the unit is the water coming from. turn off the water tank, check all connections. I've had two leaks from defective/broken parts. The company replaced these parts free of charge. If parts are broken and you purchased through Amazon, go to Amazon web site. prior orders, contact supplier. explain problem. When I did this the company emailed me within 24 hours. hope this helps/ good luck/Craig

I do not have this experience yet. It seems like the heater should be shut off when power goes out, restarting the unit should require manual reset. Hope the unit is designed this way.

If you have it hooked up right water takes a while to come out the spout because hot water is dispensed when cold water is introduced into the tank to push the heated water out. The tank is not pressurized. Check your hookup once more and be certain you have power to the unit. If it still doesn't work you may have a defective heater.

hard water will clog up the coil inside the heater you should get a water softener it wont work if the power goes out

Return it. Something is definitely wrong with it. I've had mine for several months now. It runs for hours and shuts off by itself when reservoir is empty. Yours is definitely defective.

Typically the ticking without turning on indicates a lack of gas or lack of oxygen. Your water heater needs a ventilated area.

I've had no problems with mine, so as a guess, maybe plumber forgot to turn back on the hot water or didn't connect both pipes?

The water doesnt ever get hot unless I add it hot. Maybe mine doesnt work like it is supposed to, but it has never heated the water.

It could be a valve shut off at the Bidet not working properly. I think you should return to Amazon for replacement.Shut it off from your water supply to the toilet or else your water bill be enormous. I have it over six month and no problem.

mine doesnt have an ''on-off'' switch,, check the batteries and make sure they are in the right position,,after that the 3 control knobs I played with them a little in the beggining,, but that was mostly to get the hotest water I could,, good luck

You do not have to turn on the kitchen faucet. YOu may have not hooked up the supply line correctly. Or if you have a supply line shut off to the tank, is this still in the off position?

Are you using hot tap water?, is the red light coming on? and make sure you turn it on to warm up. I do know using hot tap water makes a difference. Other than that I don't know....

Most obvious thing: check the circuit breaker. It is probably not the same one that runs the pump. If you are not familiar with electrical troubleshooting, get professional help. Otherwise, make sure that the heater is getting electricity. If not, get professional help. Otherwise, shut the power off and check for continuity of each component. I'd start with the heating elements. Use your phone and take a picture of the wires on the elements. Remove the wires from the elements and test with an ohmmeter (if available). Each should read about 10 ohms. If either element is open, it will need to be replaced. Replace the wires. Next check the thermostat. Take a picture and remove the wires. Assuming the water temperature is low, the thermostat should be closed and your ohmmeter reading near zero. If it's open, it will need to be replaced. Replace the wires. Next, check the high temperature cut off. Take a picture and remove the wires. Like the thermostat, it should be closed. If it's open, it will need to be replaced. Replace the wires. If it still doesn't work, get professional help. Hope this helps, ..j

Make sure you follow the manufacture's instructions. Wait the amount of time specified and use the steamer. The steamer will stop working after a few minutes and you will have to wait until the water heats up again, but after this you should good to go a few minutes and not a few seconds. If it only runs for a few seconds, make sure the fittings are correctly installed and try again. After this I would call the manufacturer for assistance.

I had a similar issue just the other day. It seemed the water temp wasn't moving. I unplugged it, let the heater sit (in the water) unplugged for about 20 minutes. Then plug it in again. I think the heater needs time to get acclimated to the water temp, before the filament or whatever starts cooking. Give that shot before you start slamming the heater against the wall. = )
