Looking where to start in solving broken(?) heating system on 470e year 2007. It isnít operating and I have only a basic manual. Any ideas where to start tracking the heating system so I can begin the trouble shoot.

Hi Sandy
If you look at my profile, you will find a few informations about me and my boat - you should try to publish a few informations about yourselt too!
It will be easier to respond to your questions if you tell us the name and model of your heater.
I can also recommend the search function on this site:
Choose Advanced search>All Forums>Any Date ,,,,,,,, and search e.g. "Webasto"
The manual is available on the net, or ask me, and I'll send one.

In my boat I have a Webasto 5000 and the search starts with checking the 20A fuse located near the battery. In my boat it is located in the battery compartment. It is not marked. You ought to know, the Webasto is powered directly from the battery, and it is not turned off when you cut the main curcuits. This is because the heater needs current in the cooling down period, when the blower is running. If you have power (green light) on the heater control knob, then you check the F-codes.
As you see below, the fuel line needs to be free of air, so if you ran out of fuel, the heater will not start.

FROM THE MANUAL:

Initial Operation
After the heater has been installed, the fuel supply system
is to be bled thoroughly.
NOTE:
Owing to the low fuel consumption it is required that the
heater be turned on repeatedly to fill the fuel line leading to
the heater.
During a test run of the heater all connections are to be
checked for leakage and security. Should a malfunction of
the heater occur during operation, fault isolating measures
are to be performed.
Shut-Down on Faults
Faults related to individual heater components and malfunctions
during the start-up sequence are detected in the
control unit.
The heater is shut down (fault lock-out) in the following
cases:
- no or unsuccessful start-up
- temperature sensor defective
- temperature limiter (interruption or short-circuit)
- glow plug defective
- insufficient fan speed, short circuit or interruption
- fault in the metering pump circuit or overheat protection
circuit (during start-up phase only)
- undervoltage of less than 10 volts or overvoltage of
more than 15 volts and for longer than 20 seconds
(aplies to 12-volt heaters)
- undervoltage of less than 20 volts or overvoltage of
more than 32 volts and for longer than 20 seconds
(on 24-volt heaters)
- control unit defective
- overheating
Fuel supply will be interrupted in the event of overheating.
An after-run cycle is performed as is the case when the
heater is shut down manually.
After the after-run cycle has been terminated, the control
unit is in the fault lock-out state.
An overheating condition is indicated by 10 flashing light
signals of the operation indicator.
Eliminate cause of malfunction.
To deactivate the fault lock-out, the heater is to be briefly
(min. 2 seconds) turned off and then switched back on
again one time.
Fault Code Display
If the heater is equipped with a combination or standard
digital timer, a fault code is indicated on the display of the
digital timer whenever a malfunction has occurred:
(The code may be shown as a blinking light, e.g 4 blinks = F04).
F 00 Control unit failure / incorrect parameter set /
warm start detection
F 01 No start-up (after 2 start-up attempts)
no formation of flames
F 02 Flame extinguished (repeated >5)
F 03 Undervoltage or overvoltage
F 04 Premature flame detection
F 06 Temperature sensor interruption or
temperature sensor short-circuit
F 07 Metering pump interruption or
metering pump short-circuit
F 08 Fan motor interruption or
fan motor short-circuit or
fan motor incorrect speed
F 09 Pencil-type glow plug interruption or
pencil-type glow plug short-circuit
F 10 Overheating
F 11 Temperature limiter interruption or
temperature limiter short-circuit
F 12 Setpoint transmitter (interruption / short-circuit)

P.S. Search in 341/342 "White smoke from heater exhaust"

Sandy,

Look back on my posts too, our 2007 470e was fitted with an Airtop 2500 I think, that had to be altered to pass EU requirements, it was never intended for anything other than lorry cabin use and so constantly cuts out and won't fire up.

I've been in to great detail to find this out and you might have exactly the same model as we have.

It won't work and needs replacing.

If after reading my article you feel you have exactly the same issue contact me through the private system ad I'll discuss or happy to do so in public.
