Call the manufacturer to order one. It should be anywhere from 8-11 dollars. The manufacturer's number is usually printed on a sticker on the heater.

I replaced my hoses due to a leak and filled up the tank but when i switch on the breaker the top of the tank where the electrical wires go in started to smoke . The water got under the cover.

Dear Shata,
Understand that water & electricity together are so very bad that the two of them together can kill you.
Now, it sounds like you have water into the jacket of the hot water heater.
Although this is not "fatal", getting the water out and getting the heater insulation to dry out may be nearly impossible.
If you, for example, just left it sit all alone, it may never dry out, as the wet insulation needs plenty of air to dry, and the outer metal jacket will prevent any air getting to the wet insulation.
(If you had no monies, and were terribly creative, I suppose cutting a 2 or 3 inch diameter hole in the outer metal jacket and attaching a "hair blow dryer" to the hole you have made, and turning it on high might blow enough air into the chamber between the outer and the inner walls to dry out the insulation, but it could take a week. Obviously, the connection would need to be air tight, and you would need to remove the plate on the top for the wet air to go somewhere.
The last repair I suggested is NOT an accepted fix, it is just an idea.)
God bless your efforts.

How to clean igniter on Mode N-0751M-DV

This is a Noritz Tankless.
That whoosh is excess gas being ignited behind the normal lead/lag time for G-Valve opening and igniter on. Might be the Igniter but you'll need a new igniter gasket as if you pull the igniter assembly and clean ONLY WITH A GREEN SCOTCHGUARD PAD, you'll shred the gasket and need a new one. NEVER sandpaper an igniter it is coated and sanding destroys it.
Also may be a flowmeter signal problem where flow is sensed but ignition signal is slow to igniter but on-time to gas valve opening resulting in excessive gas pocketing in HE before a clean ignition.
I'd say Tech Service Issue as this gas can pocket in the extreme enough to blow the unit off the wall with a late or slow ignition spark.

Boiler ignition failer

Try adjusting the gas to air mixture and flow rate. I don't work well in very cold weather, either. I think that's fairly typical. Even a diesel engine is difficult to start in cold cold weather. Perhaps heating the room where the boiler is would help or at lest insulate the room well. Including stopping any drafts that may be causing a windy condition in or around the combustion chamber.

Factory-installed heat traps can cause this problem:

Remove heat traps, or heat trap inserts, or heat trap nipples.
Make your own heat traps, and save 4-9$ per year, using flex copper connections, or reconnect pipes in heat-trap configuration.
Always insulate pipes.
With electric heater, pipe insulation can run all the way to tank.
With atmospheric-vent gas water heater, the pipe insulation cannot obstruct air intake at draft hood. With power vent gas, the pipe insulation can run all the way to tank.

Light flashes three indicating sensor failure where is this sensor i need to change

Whirlpool energy smart electric?

Replace thermistors.
Remove upper and lower covers, They are located under the foam insulation. Cut back insulation. Insulation must be put back when finished.
Call Whirlpool for parts, and they will also send instructions.
You will need model and serial number from label on side of tank.
This will also determine if 6 year warranty is in effect that will cover cost of parts.

Rheem/Ecosense, ECO-180DVP, tankless water heater,flashing code 11

Unknown if this is new installation.
New installation, you may need more gas to the unit.
Call the propane dealer.
The dip switches for selecting LP or NG may be set incorrectly.

If this installation worked before and stopped working:
Before calling service technician, copy following link for troubleshooting resources:

Error code 11 is ignition failure.
Keeping up with regular maintenance can eliminate a lot of common error codes, but the cost is greater than expected savings from owning a tankless.
Regular maintenance such as cleaning combustion parts, checking gas pressure, testing solenoid gas valve, sanding carbon off the igniter, checking igniter wiring harness, etc.

I have an Atwood hot water heater in a Bounder motorhome. When I turn on the switch to fire up the electronic ignition, it instantly blows the 12v fuse. An inspection of the unit shows wiring with melted...

My guess is that you may have or have had a spider web or other debris in burner tube that caused flame to back up, thus burning some wiring but, have someone experienced check it and clean it. The wiring if not burned too bad may be able to be repaired/spliced.

I have a Rheem direct vent gas water heater. When

If you are not seeing a spark at the pilot assembly where the pilot flame lights, then it is probably not sparking in the right place. You may have a short in the wire or a cracked porcelain ignitor, causing it to spark elsewhere. If you can remove the access panel, you may have to relight the pilot manually with a butane lighter. To resolve the issue of the flame blowing out, make sure your vent outside has a cap on it and that the vent is not partially blocked with a bird nests, etc. Hope this helps. Douglas

Reliance gas water heater 40 capicity, has a leak on the top

Most likely only one of the pipes is leaking but weaping enough to cover the top and indented places near both inlet and outlet. This leak has most likely penetrated all the insulation and is a problem throughout the tank wrap insulation...If you are able to blow air continuously long enough to determine which connection is leaking then fix it. It will likely to take quite a while to dry out all the insulation if the water has migrated down into the tank wrap... If you determine that the insulation is waterlogged, you may be able to drill several small holes in the external cover.
good luck
