Code 11. had hot water last night

Code 11 is for no ignition.
Here is what I find:

Check that the gas is turned on at the water heater, gas meter, or cylinder.
Ensure gas type and pressure is correct.
Ensure gas line, meter, and/or regulator is sized properly.
Bleed all air from gas lines.
Verify dip switches are set properly.
Ensure appliance is properly grounded.
Disconnect EZConnect™ or MSA controls to isolate the problem.
Ensure igniter is operational.
Check igniter wiring harness for damage.
Check gas solenoid valves for open or short circuits.
Remove burner cover and ensure all burners are properly seated.
Remove burner plate and inspect burner surface for condensation or debris.

IF it has been working fine and now it isn't, I would suspect an ignitor problem.

No hot water code 11 keeps coming on had system for 5 years

Before calling service technician, open following link for error codes, Rheem chat, and possible manual:

Error codes are considered start-point for troubleshooting.
Error 11 is 'no ignition'
Without ignition, the burner will not turn on and heat water.

This problem can be caused by low gas pressure, air in gas line, defective tankless parts such as gas solenoid, loose electrical connections, improper electrical grounding, bad igniter, etc.
Problem can also be caused by combination of problems.
Good news is that error code shows 1 code and not multiple error codes that can indicate larger failure including PC board.

Each tankless instruction manual recommends yearly maintenance where technician will clean burner parts, bleed gas line, check gas pressure, check air and venting, etc.
Yearly service covers the cause for most common error codes.

Most gas water heater problems can be solved by having service technician perform yearly maintenance. Or by doing maintenance yourself.
This maintenance includes cleaning burner parts and combustion chamber, checking gas pressure and supply, bleeding air out of gas line, checking vent draft, making sure air supply is adequate and not exposed to chemicals, cleaning air intake. Also adjusting flame sensor so it is positioned correctly. If water heater is connected to electric circuit, the outlet must have correct polarity.

You can get gas to appliance indicates the gas control valve and water heater are not locked out. But the gas control valve thermostat can still be bad.

Open following link for illustrations, typical service manuals, and maintenance information, and images of gas control valve thermostats.

Hydrapower 10h -pilot lights but gas wont light only lights when I tap the pilot tube. Then works for a while and reverts to not lighting the gas again

First suspect is air in gas line or dirty combustion parts.
Typical gas water heaters today suggest cleaning burner parts yearly, including bleeding air out of gas line.
Use a burner brush to clean tubes:

Other suspect could be faulty wiring or bad gas valve.

Hi, Please do massive / longer bleed on/off for several time and get it retry. If problem still persist, I worry you have problem on your controller and need repairing at dealer.

The nozzle size and gap completely are designed to each burner, if the bock water heater had a becket burner than you would be okay with the gap, if not then what I would do is check the manufactures manual for proper nozzles and gaps of electrode assembly
