Webasto fault

[PabloPicasso]

The Vevor 5 kw fits straight into a Webasto EVO 3900. Bracket and all. Most Chinese heaters appear to be pretty much identical, apart from the different housing colours and the control unit.

Some of the chinese control units can be programmed in their operating parametres, such as pump frequency, fan speed, etc. Mine does not do this and it has not been needed. The access code, if your controller happens to have this feature, is 1688.
The newer controls may have an App function that allows you to operate the heater from your phone. I really have no idea why I would need that.


I tried adapting/using the Webasto cabel as well - it works for communication lines, but the power supply requires a heavier gauge.

All in all, it took me 30 min to do the switch while at anchor up some wet and cold Scottish loch in the highlands. It started at first try, still does, and after ran, pretty much, for two months straight. After an almost 12 month hiatus, it started up again at the first attempt. Out of interest and to see if the original Webasto pump was any quieter, I looked inside and there wasn't even a speck of soot. As stated, it doesn't work with the Webasto pump, but the Web's rubber harness made a remarkable difference to the ticking sound.

Here in Brittany, the local suppliers want 2800 Euro for a new 4 kw Webasto ... a 5 kw Vevor can currently be had for 84.- Euro.
As I am writing this from the comfort of my v-berth, I can barely hear the chinese replacement humming away to take the morning chill out of the cabin.

Best, A.

Worth noting the silencer is dangerous and needs to be replaced, the fittings and clips are also rubbish and need to be replaced, you can use some/all of the Webasto ones.

Personally, i wouldn't fit one to my boat, i would fit a genuine Autoterm one.

Yes, I would use all the fitted existing webasto accessories.

Hard to justify the cost of the autoterm unit given how little use it gets.

Now we have cooler weather I tgought I'd run my webasto heater

Turn the dial and nothing happens. The dial quick flashes 5 then slow flashes 9.

I've not used the heater for many months, it was working fine in the spring.

Whats the issue, and how do i fix it?

Surprised that noone has mentioned the state of the battery voltage. After a long lay off and no use it is worth trying more than a few times to start up. But the battery voltage is important and should be veruy healthy. Try running the engine and then start as this will ensure good voltage.

The reason no-one has mentioned the battery voltage is because the fault code says it's the glowplug, if it was low voltage the fault code would be 03, not 09

Did fit one of the Russiaspatchers ( Autoterm ?) when they first appeared on the UK market.
An "acquaintance" frequently involved with installing heaters with a local authorized Webaspatcher dealer, decided to buy one purely to dismantle it and to discover if any bits would fit genuine Ebers etc. He imported it directly and the cost of taxes/fees and delay in receiving it made it totally uneconomic ....let alone getting any back up if it went wrong. Nothing useful would fit.
He then reasembled heater and fitted to his own boat.
Shortly afterwards a company started to import them, my Eber then died ( Mid December) and quote of probably £275.00 + carriage to fix plus need to send it off and return.
Ordered a Russia spatcher, fitted just a few days later, only mod was a Heath Robinson affair to get the warm air output of heater to match existing vent system on a 1980s Princess.
Being hard of understanding of the most basic controller ever, failed to get it to start and a plea for help, very fast response with a very patient explanation what was doing wrong. Unit of course promptly fired up, still going strong when boat sold.
The sheer joy of actually hearing any warm air heater start when required , is beyond price.

This reminds me that I must fire up my eber and give it a good hard run this weekend as it's only done cold air blower (for screen demisting) for ages, better to find out before it gets too chilly.

AH! Did not realise you could diagnose the fault from the flashing light in the thermostat control knob that the OP posted. LEARN something new everyday. Still I suppose even after counting the number of times the light flashes (in my case constant flashing if it does not fire) you still need some reference manual to tell you what the codes mean. Some older installations may not have this to hand.
So apologies for my ignorance of modern tech.. My experience of my 20+ year old webasto does not extend to having any jproblem with Glowplug. Always check the fuel, pump, and battery after a long lay off, and I have never seen a fault code in 20 years.
