There is power to the system but when you turn water on elements do not come one and heat water. all phases have 238 volts to them. why will system not turn on and heat water


Do you have 3-phase water heater? Is this balanced or unbalanced 3-phase unit. Add comment and describe product in detail, including brand since i have some service resources for both types.
Or do you have ordinary residential split-phase 240Volt Bosch tankless computer that heats water, and has 2 or 3 separate elements, and a separate circuit breaker supplying power to each element? And testing across both hot leads coming from each breaker yields 238Volt?
Copy following link for Bosch tankless manuals, with brief troubleshoot section that does not provide detailed service procedures for repairing tankless computer:
http://waterheatertimer.org/How-to-wire-Tankless-electric-water-heater.html#manual
If this is new water heater, then call installer. If you installed yourself, then remove tankless and return to seller for refund.
Tankless computers require certain amount of water flow to activate computer sensors. Turn on Hot tap and listen to pipe to hear if water if flowing through hot pipe. Check for crossover:
http://waterheatertimer.org/Crossover.html
Clean water filter usually located just above where cold water connects to unit.
Delime tankless ... and use water softener. Tankless cannot be exposed to more than 11 grains hardness in water, or parts will fail within 2-3 years. Simply deliming tankless heat exchanger each year will not maintain full efficiency... although for typical family of 4, tankless comper water heater costs $100 more to operate than tank-type heater according to manufacturer's promo literature and independent studies.
Call local technician who specializes in fixing tankless computers. For plumbing problems call local plumber. These are two different things.
If tankless computer is older, then cut losses, and buy tank-type electric water heater at Lowes for $285 and make quick changeover and have hot water same day. Sell old tankless on ebay and cheat next guy, or sell at scrapyard for $3 per 100.

Tankless should never be installed with plastic pipe, PVC or CPVC etc.

Before calling service technician, open following link for Bosch tankless troubleshooting resources, including Bosch contact information, typical manuals, error codes, tech support, parts, fuel-saver calculator, service bulletins, water heater forum, fixya links, disclaimers, and links for finding service technician.
http://waterheatertimer.org/Troubleshoot-Bosch-Tankless-water-heater.html

Read manual cover to cover, make sure tankless receives yearly maintenance as outline in manual.

Where do I find model number or serial number?I turned off main water valve to replace a leaking pipe and now I can't turn on the water heater. How do I do it?


1) You posted under Bosch tankless water heater.
There should be a nameplate on front of unit or located where you can see it.
http://www.boschhotwater.com/HelpfulResources/TechnicalSupport/BoschAquaStarModels/2400ESTechSupport/Troubleshooting/tabid/1295/Default.aspx

Bosch problems at Fixya:
http://www.fixya.com/support/p949576-bosch_1600h_lp_liquid_propane_aquastar_a/solutions

Bosch has online tech support form:
http://forms.boschhotwater.com/Home/BoschTechSupportForm/tabid/614/Default.aspx

2) Replacing water valve probably loosened build-up inside pipe that lodged in water heater or inside elbow just beneath tankless unit.
If water flow is stopped or slowed, tankless will not operate.

3) Remove pipes and see if clog can be flushed.

4) Also U-tupe search "delime tankless water heater" and technique used for deliming will be good way to clear out tankless clog and sediment.
Your tankless should be delimed each year anyway.

5) Read your manual cover to cover, and see words 'troubleshoot' and 'maintenance' are used throughout manual. Get acquainted with your water heater and manual, because tankless are maintenance heavy, especially if conditions are not optimal and as unit ages.

6) All costs are energy. Install tank type water heater for ez do-it-yourself repairs and maintenance.
Tank type work under all types of adverse conditions and water pressures and water conditions, and even withstand sediment build-up for several years. Of course tank-type pipes can clog too.

Water not hot enough


Often this is a problem of gas piping. It is likely too small. The pipe should be 5/8" copper or larger, or 1/2" Black iron or larger. The gas regulator (if it is LP) will need to be turned up from 9 inches water column to 11 inches water column when all gas appliances are operating.

I need to convert this water heater to natural gas. Is there a kit available to do this?


No kits are available to convert his unit to NG. This is because the LP uses copper pipe and is within code, the NG uses black pipe and each unit is specifically designed, entirely, to use the gas associated with the unit.

My Bosch on demand water heater is clogged. I cleaned the inlet line but seems to be inside the smaller copper tubing. HELP!


If you can access the pipe that is clogged, Poor some lime away into it . Let it sit and ad more as needed. the calcium will sofen and ca be flush out. Takes patience. Once you get some flow, fill the tubing with a descaling solution (hardware store) and let it sit. Pool acid works but must be thoroughly flushed out. be careful with acids, always wear gloves.
