Eberspacher problem

[Tarka1]

After a trouble free three years our Eberspacher is starting to misbehave! It fires up OK but shuts down occasionally for no apparent reason. The green light in the rotary control unit is left flashing (4 flashes then a break) after these unexplained shut downs.
Any suggestions as to what the problem could be?

Turn the lights down and turn up the music, and you'll enjoy the experience.

You should get out more!!

Check your fuel. They are intolerant of even slightly dirty fuel.

What is the condition of your battery? Dirty fuel, and low voltage are the two main problems.

Hi, just come on here to see if I could see if anyone else was having same prob as me, and hey presto its the first post. My D1LC runs for 10 or 15 mins then the flame goes off and the heater shuts itself down correctly, the green light on the rheostat is flashing (not sure if there is a gap after 4 flashes). The batteries are good and the fuel is good, if I turn the rheostat off and back on it fires up fine. I have today removed the heater from the boat so I can have a better look, but the first place I will be looking is the overheat thermostat to check for correct operation, and then the exhaust silencer to make sure the its not blocked or even partly blocked thus causing the unit to overheat. I checked the outputs were clear before removing heater, hope this gives you some more ideas and I will post back if I discover anything.

Re: Eberspächer problem

where did your heater come from?

Has it ever worked properly, it might have a timer on it, some did, BT fitted timers to all theirs, you may have to bypass it?

maybe?

Maybe someone could write to espar and ask for the fault codes so we can all have them on file?

Re: Eberspächer problem

The flashing (4) is a code indicating exactly what the problem is.
Get hold of an Eberspaher booklet (sorry mines on the boat in the Med) and it will should give you the required guidance.

You can download the tech manual from http://www.espar.com/htm/tecmans.htm

Re: Eberspächer problem

Ours becomes unreliable every 3 years and we - at huge expense- send it in for a decoke. However first check the fuel filter in the back of the pump (making shure that you hold the pump with a spanner to stop it twisting inside). we wash it out with fairy liquid ( or buy a new one)

Re: Eberspächer problem

The heater came fitted to the boat, it had worked faultlessly for three years, then had been removed, serviced by eberspacher, used twice and then I became the owner and never worked correctly. I have downloaded the manual and the only error codes in there are ones which the special (and presumably very expensive) diagnostic box give out. It doesn't even mention the light flashing. I have had a look at mine today, it doesnt look very carboned up glow plug, screen etc all look good. However the flame sensor and the overheat limit switch seem to be in exactly the wrong places as the drawings in the book show them. I was going to swap there positions round but they are both fastened to the heat exchanger in different ways and so wouldn't swap. Next thing to look at I suppose is the fuel filter in the pump but thats still on the boat and so will have to wait /forums/images/graemlins/confused.gif

I think that after 3-4 seasons the time may have come to strip down and service the heater! If I find anything amiss I'll let you know.
