eberspach not starting :-)

Are you measuring those voltages at the actual heater, or at the battery? Have you tried starting it whilst the engine's running, or whilst the battery charger is on?

thanks, happy to clean the glowpug/pin.

where is it / how do i get it out ??

Its on top of unit, depends on what version you have as to wether a glowplug or glowpin fitted, the later version has a glowpin. To remove the guaze you really need a special spanner to remove plug/pin first to allow access to gauze.When you remove gauze you generally knacker it so a new one needs fitting.

Before pumping it will check/test the following:-

1) Motor up to speed.
2) Pump is in circuit, and not short circuited.
3) Overheat sensor (inside heater) is not reading over-temp or open circuit.
4) flame-sensor (also inside heater) is not reading high or open circuit.
5) Is temp setting (thermostat) calling for more heat.

Worth checking...does the pump click nice and cleanly each time you connect/disconnect it directly to your battery terminals?

I've fixed at least one Eberf**ker every year for the past 10 or so years, so sort of got used to them now.
 
Another problem can be water condensed over the winter in the outlet pipe loop or s bend. A tampon on the end of a coathanger wire can be inserted to soak up any water and this may restore function
 
You don't need a special spanner, an 8mm for the small nut that holds the wires on the top of the plug and a 19mm or 3/4 spanner for the plug itself. When the plug is out you will see a small tag which is connected to the screen, make a note of the position of this tag and using a pair of long nose pliers pull and wriggle like mad and with a bit of luck the screen will come out. The screen is quite tough and will take a fair bit of abuse. Having said all that I think your unit has "locked out" and needs to have the fault codes read and the faults repaired.

That's most interesting. I was looking an a new D4 installation the other day and couldn't work out why there was a small coiled copper pipe, with what appeared to be a blanked-off drain connection, attached to the exhaust outlet bend of the heater. Now I know.

It's not a problem I have encountered myself (though have encountered nearly all other eber probs!!).

I think you are talking about the old version.....the new models use a glowpin and not a glowplug...you need a small box spanner ( smaller than 19mm??)with cutout for cables to access the plug.....this spanner comes as part of a new glowpin set.....more probably the guaze though, would fit a new one as getting the old one out you will more than likely damage it.

I suspect an electrical problem like a faulty relay , because if it were mechanic like an obstructed air duct or dirty flame sensor or faulty heat sensor it would at least pump for some time . Is the glow plug glowing ? Disconnect fuel line and glowplug and check !
 
in my older unit, there are two relays, both failed so far: one for checking the motor (switching the motor off for a second and switching in a resistor and messuaring the volts generated by the motor, doing so every minute) and a second relays for switching the motor on and off, directed from the electronic box. You can check the second relay easy: switch the unit to "blower only". If that fails, most probably that relay is blown. Just happend to me 2 weeks ago with a weather forecast of -9°C. I replaced that relay with a wire and a large spare relay on the outside
