Heater error codes explained

We have three controllers. What shape is yours?  Follow the correct table of codes.

Please read fully as error codes can be created for a variety of reasons, the two most common, low voltage and lack of fuel can show as different codes, especially low voltage.

WARNING

Call outs for E08 or E10 fuel issues can be chargeable as these can be avoided by ensuring you do not run low on fuel as advised on installation day.

Just like your vehicle, running out of diesel can require that your fuel lines are purged of air to remove any air block.

You can attempt this on your own using the manual pump override detailed in your instruction booklet, however, to do this you will need to monitor the fuel lines and also the fuel filter under the vehicle as over fueling can also cause further issues. Our standard call out fee is from£60 depending in your postcode area, plus time  over 30 mins on site to resolve at £39.00 per hour / part hour.

On restarting it is highly likely that the exhaust will produce thick black/grey smoke until it burns any excess fuel in the combustion chamber / exhaust pipe and silencer. This is normal and will clear in due course if left running.

IMPORTANT : It has been reported a few times that customers have had items placed in their exhaust to block it!  Unit will respond with E10 and fail to start. Please check exhaust / silencer is clear from any blockages.   

Service / warranty repair, callout.

If a no heater fault found is discovered by our engineer (I.E Fuel related, Power related) there will be a callout charge of £60 plus labour applied for the visit. An area charge may also be applicable, depending on callout postcode area. We aim to appoint within 10 working days, however this may be extended during holiday periods.

Service / warranty calls can be  made by calling our office on 01555 728515, Mon - Fri 10am to 6pm, alternatively you can raise a service request by pressing the large RED HELP button on our website.

Diesel additives:-  Please DO NOT add any diesel additives to your vehicle tank if fueling your heater from there.

The additive can cause your heater to flame out and issue a no fuel E08 warning. The effect of this is additional sooting, causing an exhaust blockage.  Service calls discovered with additives will be chargeable as it is not a heater fault.

 

Colour controller 

E00 - NO ERROR

E01 - Under voltage - your battery does not have enough power, please recharge.

E02 - Over voltage - Voltage is over the permitted level, reduce voltage to 12v.

E03 - Glow plug fault. Check leads and replace if necessary. Can be low voltage.

E04 - Fuel pump disconnected. Check lead to fuel pump, check connector is clicked in place. Can be low voltage.

E05 - Overheat. Check air intake is not restricted at rear of heater, check fan is not impeded. Ensure that the installed heat vent is not blocked / restricted. Also check that heating duct has not been crushed, thus  restricting air flow. Callouts for restricted air flow or crushed ducting will be chargeable as follows £60 call out fee plus £39 per hour/ part hour over 30 mins on site. Plus any required replacement parts. 

E06 - Fan motor fault - Normally caused by low voltage.

E07 - Communication between controller and heater broken, check lead and connection plug. Again can be low voltage.

E08 - Low fuel or air in fuel lines - refuel vehicle, check fuel filter is full. Can be low voltage.

E10 - One or more of the above error codes and the unit has been restarted a number of times without success.

Most errors can be self cleared by using the above  table of codes. E08 lack of fuel may need to be restarted a number of times to refill fuel lines. You need to check fuel filter is FULL with NO air lock. After a few failed attempts the heater should ignite and clear errors. Callouts for no fuel will be chargeable.

If the heater attempts to start and then shuts down with NO error code being displayed, it is an indication of possible low voltage. To check this, press OK button to display battery voltage, once displayed press start button and monitor voltage. if it drops below 11.2v, you need to recharge your battery. If you have a split charge relay fitted to your vehicle, start the vehicle and retry starting using the same procedure, again monitoring voltage and any possible error code(s) DO NOT RELY ON A SEPERATE VOLTAGE METER as this only show headline voltage, not how your battery is performing under load unlike the heaters own display. 

But I haven’t run out of diesel?

On installation the fuel stand pipe inserted in to your tank is placed approx at 1/4 tank level to ensure heater does not drain your tank. If you allow your fuel to drop below a 1/4 tank it is possible that the fuel lines and fuel filter may back syphon in to the tank as it is below the level of the standpipe. To eradicate this, do not allow your tank to go below 1/4 full. Thus you can run out of fuel without actually being aware that you have.

Low voltage E01 can cause unit to throw numerous error codes as the voltage in your battery is not enough to fully power the unit. You need to ensure your battery is fully charge and healthy at at least 11.8 volts constant under load.

 

Oval controller

E01 - No power to fuel pump, check connector is seated correctly. Can be low voltage.

E02 - Check glow plug - replace if necessary. Can be low voltage.

E03 - Fan motor disconnected. Can be low voltage.

E05 - Over voltage - reduce voltage to 12.5v

E06 - Under voltage - charge your batteries.

E07 - Controller disconnected - check controller lead and connector is secure. Can be low voltage.

E08 - No fuel. Refill your vehicle. Can be low voltage.

E10 - Repeated attempts to restart with a previous error code.

E12 - Air inlet restricted. Check rear of heater for obstruction(s) Can be low voltage.

Most errors can be self cleared by using the above  table of codes. E08 lack of fuel may need to be restarted a number of times to refill fuel lines. You need to check fuel filter is FULL. After a few failed attempts the heater should ignite and clear errors. Callouts for no fuel will be chargeable.

If after checking the above tables you cannot get your heater to start, please click the help button below to request support by raising a support ticket fully detailing your fault.

Our staff will be in contact as soon as possible to assist.

Refiling the fuel system

 

Firstly, refuel your vehicle to above quarter tank level.

 

For our Top 2 controllers on this page follow instructions number 1. For the oval controller follow instructions number 2

 

Number 1

BLACK CONTROLLER : On the controller press the down arrow button  and OK button together.  BLUE CONTROLLER : On the controller press the down button and settings button together

Screen will change to H- OFF press up arrow to change to H – ON the pump led will light and pump will pulse fuel. Monitor fuel filter and fuel lines, sometimes it is better to disconnect the fuel pipe from the heater, thus it will not over fuel, and this will also assist in expelling any trapped air within the pipework.

Ensure that all the trapped air is expelled from the fuel filter by manipulating it whilst pump is pumping.

The pump will time out after approx. 2 minutes, to switch on again press the down arrow and then press the up arrow to switch it back on again.

To stop manual fuel pump either press down arrow or press settings button.

Reconnect fuel line if disconnected and restart heater.

 

Number 2

Please disconnect fuel line from underneath heater.

Attempt to start heater and heater will commence fuel pump, keep restarting heater until both the fuel filter and all the pipe work is full of fuel.

Ensure that all the trapped air is expelled from the fuel filter by manipulating it whilst pump is pumping.

Once steady fuel is coming out of disconnected fuel line. Reconnect and start heater.

 

Our exclusive Challenger C series diesel forced air heaters can and will heat the average motorhome to 24 degrees in roughly 5 - 6 minutes. Can your existing lpg Truma do that?  Can it do it while you drive?  Challenger can! Ask your rear traveling passengers just how cold in can be back there. 

HEATER SIZES - What is best?

2kw - Small to medium sized vehicle / boat

4kw - Medium / large sized vehicle - best all round performer both small, med and large vehicle / boat.

6kw - reserved for the larger vehicle/ boat, normally with multiple outlets required.
