Assuming you are talking about the temperatur/pressure relief valve, it is stuck open.
1. Turn off gas or electric to water heater
2. Close water supply to water heater
3. open hot water faucet on nearest fixture to depressurize hot water system.
4. close tpr valve (you may have to push in on the center spine. It may be resistant to closing from sediment. If so, opening and closing several times may solve that issue.
Once you get the tpr valve closed, close the faucet and open the supply valve. If the tpr stays closed, go ahead and turn on the gas/electric and re-light pilot and turn on control etc.
If the TPR blows again, you will need to replace it. YOu can buy a new one at any plumbing supply store. Shut down the heater again, drain a bit of water out using the valve on the bottom of the tank. there is probably copper pipe connected to the TPR valve which you may have to cut or maybe can just unscrew. The TPR threads out of the tank, install the new valve (make sure to use pipe dope or teflon tape.

SOURCE: no water from hot water faucet
thanks for your question, sounds to me like you have a frozen line, I used to live in Northern, MN on a well, and had alot of time un-thawing water lines, yes it is continuous flow, sorry for having to say this but you need to immediately start tracing your hot water lines and see if you have any leaks, bulges, or ice forming on the line, tap the line with a screwdriver to hear the difference in sound when you find the frozen section, here is the tricky part, if its (pecks line, plastic) then you need to call a plumber, if copper, you can use a torch to un thaw the line, but use extream caution when doing this as many people has accidentally started fires, my best advise is to call a plumber, hope that helped, please get back to us and let us know what you find, thanks again, mr.grzz

Are you using a single lever faucet? The install guide does indicate that you may need to reduce the input from the cold water side to ensure that water stays at a consistent temperature (see page 7 of the installation and service manual). Also, remember, this is a SMALL hot water heater. So if you're running for any length of time at full output, it may not keep up with you (see page 8 of the service an installation manual). I found the manual online at http://www.airwater.biz/images_templ/bosch-water-heaters-ae3.4-manual.pdf.

check the screen on the cold water intake on the cold side,, you might have to flush the system out, and do you have the shower head water restricter in, if not you may be using to much hot water,,, how many other hot water fixtures are running at the same time? try running just the shower,,,if this is a tank water heater the dip tube could be bad that is on the cold side it takes the cold water to the bottom of the tank and forces the hot water out,, if you ar only getting a couple of min of hot water and the dip tube is bad it is not going to the bottom but just at the top and not getting all the hot water you will need a plumber
