Troubleshooting

Electrical

Shore power not charging

  1. Ensure you have power to the extension cord that reaches to the shore power plug.
  2. Check fuses on Intellipower (Green 2x30A)
  3. Check breaker in 120v breaker box
    1. Note. If there is a red display and the switch is in the middle, it’s tripped. To reset it, flip switch to the OFF position (down) and then turn to the ON position (up).

No power to devices in van

If many devices have no power, it’s most likely the breaker to the fuse panel.. 

If only one device has no power, it’s most likely a blown fuse in the panel. Two fuse panels are installed. One is in the battery box and the second is in the water box.

  1. Check the breaker to the fuse panel. Reset if necessary.
  2. Check fuse for specific device in fuse panel. Replace fuse if blown with the exact same size.

Solar not charging

If the solar is not charging, make sure the breaker is reset, and that you have unobstructed sun. If one panel is blocked, the other will still work. If half a panel is blocked, the row that is blocked will no longer produce a voltage.

Batteries not charging from the alternator

  1. Make sure the engine is on. 
  2. Check the breaker in the battery box, and, reset if necessary. 

120 volt not working

  1. Check the on/off switch on the switch panel
  2. Check the breaker in the battery box

Heater

Heater isn’t blowing hot air

  1. Make sure you have over a ¼ tank
  2. Make sure you have power to the heater by running the fan only
  3. For more extensive troubleshooting, refer to the Espar Manual.

Heater has no power

  1. Check the fuse. It’s located in the fuse panel in the water box. Replace fuse if blown with the exact same size.

Clearing Fault Codes

If too many attempts are made to start the heater when there is a wrong condition (for example too low on fuel), the heater will lock you out to protect the unit. Refer to the Espar Manual to access the back door to clear the codes.

Note: the M2 D4L is the diesel version and has the same manual. 

  • To identify codes: tinyurl.com/EsparFaultCodes
  • To access the fault codes:
    • When your Heater is acting up it will give out a fault code or error code to help you understand the problem. Find out what these codes mean and what you can do to remedy the problem. Also how to perform an Espar heater reset.
    • No matter whether it’s a connectivity issue, fuel shortage, incorrect connections, under or over voltage, heaters show fault codes that can narrow down your investigation. However multiple fault codes can even cause a heater-lockout. Below is a list of all Espar Airtronic and Hydronic fault codes with explanations and potential remedies.

PLEASE NOTE – After checking and writing down the fault codes, you can delete the fault codes that could prevent your heater from running.

The heater will indicate that there is an error by displaying a generic code and a wrench symbol. This is just a basic indication that your Espar Hydronic or Airtronic has errors stored in its memory.

Clearing Eberspacher fault codes

Now that you understand what your Espar codes mean you may be wondering how to clear Espar codes and have your heater running again.

For Espar/Eberspacher Heaters with the EasyStart Pro controller

In order to read and delete fault memory, first you need to access the workshop menu from the EasyStart Pro controller.

Open the vehicle workshop menu

  1. Scroll to the “Error Memory” option
  2. Confirm the selection by pressing the operating button.
  3. Select [Read] by turning the operating button and confirm by pressing.
  4. Read out the fault message and remedy the fault as described in the table below on this page.
  5. Then select [Delete] by turning the operating button.
  6. Delete the fault list by pressing the operating button.
  7. Always write down the Fault codes before deleting, even if no repairs need to be made.

Plumbing

Please help us in checking for plumbing leaks often below the sink, in the water box, and around the shower. Due to the vibration of traveling on the road, plumbing fitting often leaks in the first few months of install. We ensure there are no leaks when it leaves the shop.

No water pressure

  1. Check fresh water tank level
  2. If full, check the pump switch
    1. There are two pump switches: one on the galley, one on the shower. These are 3 way switches. The switches must be on either I or II. if either one in on 0, the pump will not run.
    2. The pump will not make noise when the system is pressurized. It is best to leave the pump off when not in use, to prevent pressure leaks in case something bursts.
  3. Make sure main valve off the tank is open

Low water pressure

  1. Check fresh water tank level

Shower

  1. Plug in the shower head to the spray port
  2. Turn on the pump. Adjust water and propane knobs as needed.

No hot water

  1. Adjust water and propane knobs. Not enough propane or too high a water pressure will make the water cold.
  2. Check the propane tank. Refill if necessary.
  3. Check propane quick disconnects. Make sure all fittings are secure.
  4. Check batteries (2xD) for ignition. No other power is needed for operation.

Audio/Video

TV

No power

  • Test both remote and button on TV
  • Check the fuse for the TV in the 12-volt fuse box to make sure it is whole. The 12-volt fuse box is located in the battery box with the other main electrical components
  • If other 12-volt appliances aren’t working either, check the breaker for the 12-volt fuse box. Reset it if necessary.

Bad/no antenna reception

  • Make sure antenna is connected
  • Some antennas require power. Make sure the power source to the antenna is on.
  • Some antennas are directional. Make sure the antenna is pointed towards the largest nearby city.

No video from source

  • Check source on TV from remote or from the button on the TV. The normal source is HDMI1.
  • Verify the source is on and all proper cables are connected. Refer to the Audio/Video Instructions guide in the General AV divider.

Stereo

No power

  • Check the main ON/OFF switch on the electrical panel. Noramly the issue.
  • Try powering it on with the remote.
  • Check the fuse for the Stereo in the 12-volt fuse box to make sure it is whole. The 12-volt fuse box is located in the battery box with the other main electrical components
  • If other 12-volt appliances aren’t working either, check the breaker for the 12-volt fuse box. Reset it if necessary.

Low volume or distorted audio

  • Check source volume
    • If the source (laptop, computer, iPod) has an adjustable volume, adjust volume to 75% on the source.
  • Note: Changing the volume on the TV won’t do anything. The stereo controls the audio from the TV. We’ve set the system up so the stereo volume is the master volume, because the stereo ultimately powers the speakers.

No audio (but stereo is on)

  • Ensure that the stereo is not on mute. Easiest way is usually on the face of the stereo. Normally click the spin wheel for volume to toggle mute. If there is no spin wheel, there should be a mute button near the volume adjustment buttons. Last case scenario is to use the remote. The remote will always have a mute button.
  • Verify the source is on and all proper cables are connected. Refer to the Audio/Video Instructions guide in the General AV divider.

Bad/no antenna reception

  • Make sure antenna is connected
  • Some antennas require power. Make sure the power source to the antenna is on.
