Question about Bosch & Tankless LP Hot Water Heater

1 Answer

Bosch Eco 5 Igniter keeps clicking

The igniter keeps clicking, there is no demand and burners don't go on. When hot water tap is turned on, it operates correctly, but then when water is turned off it starts up again. I changed the batteries, thinking that might be the problem but no help. It just keeps clicking away as if it is trying to ignite.

    Thank you earwel, I am sure you are right, in the meantime, after I tapped all the connections, the unit has stopped clicking so I will ignore it until it starts again

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.

When i turn on the tap the water is cold for 2 minuets then comes hot


Is this a new problem? Is it just running the cold out of the pipes before the hot water shows up? Is it a on demand or tankless system?

Fix problem immediately same day, yourself, for $385, by replacing whole thing:
http://waterheatertimer.org/How-to-install-gas-water-heater.html
Bosch posts some service manuals: or contact Bosch. Lack of error code indicates failed PC board? or bad single-handle faucet cartridge?
http://waterheatertimer.org/Troubleshoot-Bosch-Tankless-water-heater.html
Check for crossover where bad faucet cartridge allows cold water to enter hot pipe, so hot water is not drawn through tankless and burner does not activate... but this might not be problem since you hear the tankless clicking

Call local service technician to catch up on required yearly maintenance.

You need to have the flow switch looked at. The low flow of the water to the lavs and the kitchen sink, they all have as small demand next to t bath or shower,

The igniter is glowing, but no gas ignites?
So either the gas is entering combustion chamber and not lighting because igniter is positioned incorrectly -or- no gas is entering combustion chamber because air in gas line or bad gas control valve thermostat or gas line is clogged.
When you 'restart' the water heater, somehow you are getting gas to the burner and it is igniting.
I'm not sure what the flame switch is. If the ECO was cut out, the gas control valve would not send power to the igniter and there would be no gas available for 'restart.'
I would adjust location of igniter, check if gas is entering combustion chamber, clean the gas line to the burner, and bleed gas line for air, but another suspect could be the gas control valve thermostat.
Identifying numbers are usually on side of gas valve.

There is likely an onboard relay stuck in the open position.

This is a gas appliance and should be serviced by an authorized BOSCH repair center to avoid potential catastrophe.

Demand light not on when hot water tap is turned on, so ignition light is not operating.


What has happened is your starter that senses the pressure, and that sensor when activated, , then ignites the igniter, and the heater works. What happens is this sensor/Valve, goes faulty, and it will not work.It must be replaced. Sometimes too, it is the actual igniter itself, you will have to troubleshoot to see which part it is, it maybe easier to just replace both. have a look on the 'net, for a service manual for your system, it will give you a diagram and all servicing data etc. really you cannot repair anything without one. If in doubt at all though. You should contact a professional, and ask for a 'Quote" for the repair.

Hot water wont fire up when hot tap is turned on . but firing up for radiators ok


Check the diverter valve is operating when hot is on demand. Depending on the boiler [valve types differ] most have a small piston [biro refill diameter] protruding which operates an electrical switch/contact.
replace switch.if valve piston works but not the switch OR it piston not working
replace valve [or diaphragm inside]
