Fiat Toleno Troubleshooting


THERE IS NO HEATING OR HOT WATER


There are several things you will need to check to establish the fault. Firstly, you will need to check the control panels above the door.

The Truma control panel (on the left above the door) has the settings for the heating & hot water. You will need to check that these are set correctly, to do this, press the rotary switch on the panel below the screen so that the screen has lit up and you should be able to see the full display. The first image of a motorhome is for the heating, the second image is for the hot water, the third image is for the source you want them to work off i.e gas or electric and the fourth one is the fan setting. You will also need to make sure that the control panel on the right has been turned on. This panel supplies power to the trauma panel, without this switched on, an error code of 255 H will be displayed on the trauma screen. This means that there is no power to the trauma panel. You need to check that the heating has been set correctly, use the rotary switch by pressing it in to select the heating image, this should show you what temperature you want to set it to this ranges from off-30. Turn the rotary switch until the desired temperature is reached & then push the rotary switch in to select the temperature. Then use the white return button in the bottom left of the panel next to the rotary switch to return to the main display.

You can now go to the hot water setting by using the rotary switch & press the switch once you get to the hot water image, the settings here should be OFF, ECO, HOT & BOOST. The settings speak for themselves & are self-explanatory, the boost setting is if you would like hot water a little sooner, please remember if you only have gas as your main source of working the heating & hot water the setting selected will determine the gas usage. Once you have selected the required setting, press the rotary switch so that the panel remembers your choice. You can again press the white return button at the bottom left of the control panel to return to the main display.

Setting the energy source for the heating & hot water to work off. Again using the rotary switch, go to the third image which should be a gas bottle & press the switch, here you have the following displayed, GAS, MIX1, MIX2, EL1 & EL2. It is very important that you set this correctly for the heating & hot water to work. If you are on a camp site & have an electricity supply that you can hook the vehicle up to, it is always advisable to use this as your main source of power which would be EL1 or EL2. This will conserve the gas that you have for cooking, also it has the added advantage of letting you leave the vehicle hooked up & you wouldn’t have to worry if you leave the heating & hot water on whilst you are out enjoying your holiday & running out of gas. If you only have gas as your main supply, it is advisable to start the heating & hot water around 30 minutes before you require it. This will conserve the gas you have in your gas tank.

Gas

this is for when you only have the gas as the main energy source

MIX1- Electric (900w) + GAS (check the camp site you are on for voltage) this allows you to use both gas & electric as the supply for working the heating & hot water, it will mix both equally. You must have electric hook up for this setting to work. If there is no electric hook up to the vehicle, an error code will be displayed on the screen & you will have no heating or hot water.

MIX2- Electric (1800w) + GAS (all details as above for mix1)
EL1- Electric (900w) (Please check with the camp site that you are on for the voltage) this will work the heating & hot water off the electric ONLY. This is the best way to operate the heating & hot water providing that you have an electric hook up point to connect your vehicle to.

You can select the correct source according to what energy source you have available to you by using the rotary switch & pressing it to select the option required.

You will know if the heating & hot water are working as both the heating picture & hot water picture will both be flashing to indicate that they are getting to the selected temperature.


DEALING WITH FAULT CODES FOR HEATING AND HOT WATER


When the control panel identifies that there is a fault or warning it will show on the Truma display in the following format:

The triangle at the bottom of the display is indicating that there is a fault with one, or both of the applications that has been set (heating and or hot water). The fault can be fixed by identifying the code that is being displayed. You can find the code by using the rotary switch to get to the triangle & then push the button so that the code is displayed. Below is the format that the codes are displayed in, this is an example:

E 112 H
E- Fault
112- Fault Code
H- Device (heater/boiler)

The following are codes that will be displayed & how to fix them. Most of the time the faults are static, however, if you try to re set the fault without success more than 3 times it can put the display in to a locked mode & will need to be re-set, please ensure you look at the fault codes below & the remedies & take the necessary action before trying the reset, if you are unsure of how to do this then please contact the office on 0044 1942 778899.
It is important that before you start to attempt the re-set, you must ensure that both panels above the door have been switched on. the panel on the left can be turned on by pressing the rotary switch in until the screen is lit up. The panel on the right can be turned on by pressing the power button until the screen is illuminated. You can now try the re-set, This can be done by using the rotary switch (on the panel on the left) to get to the triangle & then pushing the button so that the fault code is displayed & then push the rotary switch again, if the code vanishes then you have successfully re-set the panel & it will need no further action, however, if the fault code continues to flash, you will need to leave the panel exactly like this for 15 minutes whilst the panel re-sets its self. You will know when the panel has re set itself as the fault code will stop flashing & you can then push the rotary switch and the fault should then disappear. The most common fault codes are below with remedies to fix them:

#17: summer mode with empty water container. You need to switch the heater off and allow to cool & ensure that the boiler has water in it. This can be done by ensuring that the vehicle has water in the water tank then turn the pump on until the pump stops running.

#18: warm air outlets are blocked. Check the outlets which can be found below the cooker and under the seating area. You will also find others throughout the vehicle by the beds. They have a light brown cover which should be in the open position, if they are closed and blocking the air outlets this is the cause.

#24 & #44: Risk of low voltage <10.4 v. Charge the battery. This can be done by running the vehicle and allowing the leisure battery to be charged for a short while, or you can hook the vehicle up to an electric source & this will charge the leisure battery also.

#45: No 230v in operation. Check the settings on the panel, if the energy source is set to EL1 or EL2 but you are not hooked up to an electric source you will not be able to use the heating & hot water on the EL settings, change the setting to GAS and this will allow the heating & hot water to operate. Alternatively, if you are hooked up to an electric point on a campsite, check with them that the stand has power to it or if you must pay for the electric.

#112 & #202: Gas cylinder or quick acting valve in the gas supply line is closed, or your gas bottle is empty. Firstly, check that your gas bottle is full, then have a look at the top of the gas bottle & you will see a valve on top that shows the direction for open & closed, ensure that this is open. You will see that there is a yellow toggle attached to the gas pipe that runs in to the vehicle, this should run the same way as the gas pipe, if it does not run the same way as the gas pipe this means that the valve is shut off.

#122 & #212: Combustion air in feed or exhaust outlet is sealed/ blocked. Go to the outside of the vehicle where the dining area window is and you will see a round exhaust below the window, check to see if anything is obstructing the outlets. Clear the obstruction & this will clear the fault.

#255: Heater has no 12v power supply. Ensure that both panels are switched on, this is supplying the heater with power so that it can run.

If any of the remedies do not work or if the fault code does not appear in the list above, please contact trauma & they will help you trouble shoot the fault 00441283 587960


WORKING THE HOB AND MICROWAVE


This is a straightforward operation, however if you are having trouble lighting the hob there are a few things that you can check to correct any faults.

The hob works by turning the dial in order to have a large flame or smaller flame, you will need to hold the dial in to allow the gas to flow through to the appliance. You can usually tell if gas is coming through to the appliance with both the smell of gas & the sound of the gas coming through, however, if this is not the case then you will need to check the following:

There is a cupboard under the microwave that has a row of red toggles. These are the gas isolator switches. They should run in line with the gas pipes if you have checked all of the above toggles and they all appear to be in the same direction as the pipe, You will need to check that you have ample gas in the vehicle for the appliance to work. You can check the level of gas by checking the gage that is on the right hand side of the steering wheel. You will need to have the engine running to check the gas level. The levels can be determined by the amount of green lights that are displayed on the little screen. If you have more than 1 green light displayed on the gage then you should be able to operate the hob without issue, if the gas levels are low, you will need to fill the gas tank. This can be done at some campsites; however, you can also use google to find your nearest supplier of gas.

The microwave is operated using the buttons to select which setting you want it to work on. pressing & holding the ECO button turns the appliance on, for further details you can look at the user manual here


WORKING THE TAPS


The taps are very easy to work, there is a small lever next to the tap & on the top you will see there is a red & blue square & this indicates hot (red) & cold (blue). Turn the handle to the desired setting & lift the handle to allow the water to flow. If the water is not flowing through the taps there are a few things that you can check. Firstly, check that there is water in the tank. You can do this by checking the panel above the door on the right. You can check the water levels by turning the panel on with the power button (top left)& pressing the button in the middle on the right & this should give you a % of water that is in the tank, it will be on a scale of 0%-100%. 100% means that the tank is full, if the % is very low, please re fill the water tank & the flow of water through the taps will be restored.

Check that the pump is turned on, this pumps water from the water tank, through to the taps. You will see on the panel above the door on the right has a picture of a tap. Press this so that the pump is turned on, you will hear the pump start to work immediately & the flow of water should be restored. It is important that there is water in the tank before the pump is turned on. If there is no water in the tank, the pump will continue to run & this will burn the pump out causing damage to the motorhome.

Check for air locks. If the above 2 steps have been followed correctly & you still have no running water, this could be due to an air lock in the system. You can identify this quickly by opening the taps in the kitchen, shower & bathroom sink. You will hear air coming from the taps, once the air lock has been removed you will then start to see the taps splutter water through and after a few minutes the water flow will be restored.


OPERATING THE FRIDGE FREEZER


The image above shows the fridge dials & is currently turned off, the vehicle is stationary & has no electrical hook up, therefore is working off gas in the vehicle. The fridge freezer has 3 different sources that it can work off and they are as follows:

Mains hook up, battery & Gas. The fridge should always be set to the source that you have available whilst you are in your vehicle. If you are travelling in your vehicle & the engine is running, you will need to use the battery setting. Turn the dial on the left to the picture of the battery, the dial on the right is for the temperature, you can go ahead and turn this to the correct temperature you require Once you are driving, the fridge will work on the battery. The vehicle will isolate the gas supply once you are driving so you must make sure that you have switched the dial to the battery as it will not work on gas.

If you are on a campsite and you have electrical hook up to the vehicle, turn the dial on the left to the picture of the plug, the dial on the right is for the temperature, you can go ahead and turn this to the correct temperature you require & this will now work on the hook up. This setting will save the gas you have in the vehicle.

If you are stationary & have no electrical hook up, you will need to use the gas setting. Turn the dial on the left to the picture of the flame, the dial on the right is for the temperature, you can go ahead and turn this to the correct temperature you require. You will then need to hold the dial in for the temperature & press the silver ignitor switch at the same time, hold both in for around 20 seconds. You will then see the red needle in the window move to the green half. This indicates that the fridge is working.

Trouble shooting faults on the fridge can usually be identified quickly & rectified. Once the fridge has been set, you will need to check that the fridge is operating properly. If you have the fridge set to electric hook up or the battery, you can do this by checking inside of the fridge is getting cool.

If you have the fridge set to gas & have followed the instructions for turning the fridge on in Gas mode, but the fridge does not appear to be working, there are a couple of things that you can check.

1/ Do you have enough gas in your campervan? You can check your gas level by looking at the gas level gage. The gage can be found to the right-hand side of the steering wheel, you will need to have the engine running so that the gage lights up. As you turn the engine on you will see the gage lighting up with little green lights. The green lights will indicate how much gas you have in the tank. If the gage is lit wit all green lights this means that the tank is full.

2/ Do you have the fridge set to the correct setting? Check that the fridge is set to Gas, this is the picture of the gas flame.

If the vehicle does have enough gas according to the gage, the fridge will just need to be re-set. You can do this by turning the dial on the left to the off position & do the same with the dial on the right. You will need to leave the fridge off for around 5 minutes & allow the fridge to re-set itself. You can now go ahead & turn the dial on the left to Gas, then turn the dial on the right to the desired temperature and hold it in, this will allow gas to come through to the appliance, now press the silver igniter button in & you will hear it clicking & the needle in the window to the right will start to move to green. Once the needle has moved all the way into the green you can release the dial & the igniter button. Now your fridge is operational, you will need to leave it to get to temperature.


OPERATING AND EMPTYING THE TOILET CARTRIDGE


Please ensure that before using the toilet, you have used the lever on the side of the toilet to open the cartridge, this allows waste to go directly into the cartridge. Flushing the toilet is done by pressing the button on the panel below the bathroom window. If the flush is not working on the toilet, this will be because the pump has not been turned on. Once the toilet has been used, go ahead & close the cartridge again. This will prevent the bathroom from starting to smell.

It is important that you ensure that the toilet cartridge is emptied on a regular basis. You should probably look to empty the cartridge every few days dependent upon the usage of the toilet. To empty the cartridge out you will need to make sure that the lever on the side of the toilet has been closed before attempting to remove the cartridge from the vehicle. If the lever has not been close on the inside, the cartridge will not slide out of the cupboard that it is housed in & if you try to force it out of the housing, this can cause damage to the motorhome.

The cartridge can be removed from the outside of the vehicle, if you go to where the bathroom window is on the outside of the vehicle & look directly below the window you will see the cupboard that the cartridge is housed in. Open the cupboard & you will see the handle to the cartridge & a clip just below the cartridge. If you lift the clip up towards the handle you can then slide the cartridge out of the housing. Most campsites have a specific area for you to empty your cartridge in. If you are unsure, you should ask at the campsite for the correct location. Directly above the handle on the cartridge you will see a spout that has a screw cap on, you can push the spout round to allow you to empty the cartridge easier, once you have done this you can unscrew the cap & allow the waste to flow out this way. It’s important that you ensure the cartridge has been fully emptied of all waste. You can do this by sliding the plastic plate on top of the cartridge once it is lying flat on the ground and using the toggle to the right to slide the disc open on top of the cartridge. Once you have established if the cartridge is empty you can go ahead & put the toilet chemical into the cartridge & dilute with water. Be careful with the chemical, whilst it is not particularly damaging or harmful to your skin, it is usually a very dark blue colour & can sometimes stain your hands & clothes. Once you are totally happy that the cartridge is prepped & cleaned you can put the cartridge back in to the vehicle & the toilet can be used again. Please make sure that the cartridge has been totally emptied before returning your vehicle to the depot, as you will be aware from collection, there is a charge for not fully emptying your toilet.
