Help please- truma heating & hot water not working
Dear All - please help - we are on a site caravan just been serviced and all fine, we have a swift with truma air blow heating, new can from 2016. Heating and hot water not working error message is E89H. The gas cooker works, electric works. It's cold evening we have young kids, we can't figure out the error or what's wrong. We have fuses but don't know which does the heating/water.
If if any one knows how to fix could they post a reply... We will be most grateful.

Sorry I can't help with your error codes our system is older. Do you have the option of gas? Personally I'd use that for the time being- but don't forget to removal the external cover or it won't work on gas. Should give heat and hot water to get you over the evening at least.
Here's hoping somebody with the right know will be along soon.

Hi thanks for the reply. Gas cooker working and electric working. Just not heating or hot water. Tried running on electric and gas for heating and water and that's not working either....
Anyone with advice? I know is caravaners are an experienced bunch - someone will have a Jen of wisdom.

see this thread from MMM
http://forums.outandaboutlive.co.uk/forums/Motorhomes/Motorhome-Matters/Truma-combi-heater/45987/
not looking good from the text therein....
i am suspicious when these items fail immediately after a 'service'...
I woild pop to local B&Q or late nite superstore and get a cheap fan heater or two at a tenner or less each.
these can remain as backup devices when you get your service dealer to fix the issue.
explain to them it was working properly prior to the 'service'
good luck.

...they might even be able to lend you a fan heater for the night...

Good advice by Bolero. I presume you have the Truma CP plus which I have on my van. On the display I presume the warning triangle is flashing? And turning to that brings up the error code. I am no expert but you could try a factory reset by turning the rotary button until you get to the spanner symbol PR SET should appear push rotary button to confirm. See if that will reset the system especially as it's just been serviced and they may have played around with the system. Just a thought!

bob, good thinking....the classic cure for most computer driven stuff.....unplug or reboot

What is in your manual about the error codes? I don't have anything modern enough in my 'van to display error codes, but on what does it show?
Modern 'vans usually have "breakers" rather than "fuses". You may find a list of which does what on the inside of the door that conceals them from view. In any case you can look closely at them with a torch to determine if any are in "off" position.

Thank you all- such helpful people on this forum. We did the reset no change. Heating and hot water always worked before. We have electric and gas working fine so must be the Bolier or fuse? Family will brave it tonight in thermals. We are on a 5 day Easter break so will have to work out how to fix it by calling dealer who just services it with flying colours - hoping dealer or truma customer serives can give simple fix.
Other swifts here had no idea and neither did warden- but all trying to be helpful- just didn't know the answer.
If anyone has any ideas tomorrow do Let us know- we have one day left where offices will still be open them 4 days public holidays ,when I'm sure dealer and truma won't be in office to answer calls !
Thsnks again all

Have been on a couple of websites looking for truma fault codes and the code you have is not uncommon but does not look good it could be a pcb fault ,as suggested get a fan heater as it probably is a dealer visit for rectification
Ps if you do get a fan heater go for one with a large fan much quieter than flat ones
0 -
yes, the info from the thread i posted (and other reports) suggests a PCB issue...
nip down and get a tenner fan heater and charge it to the dealer once he's fixed the issue.....ensure you let him know all was working fine prior to the 'service'....

Thanks for all the replies, I thought I'd list here what happened next to help others if they have the same error message. We spent hours on phone to the dealer engineer basically switching the whole system on and off again- to no avail. We continued our 5 day trip with no heating and no hot water. We bought a fan heater as we'd sadly left ours at home,seeing our 1 year old van just as had a service and was fine, we dint bring the heater with us.
The engineer key points:
- Error probably fuse going into trauma boiler
- Hard to access can only be done by engineer
- Not covered under warranty if it is fuse as could be blown by power surge on site. We bought our van New,it's a year old and less than 24 hours perilous to getting on site it had a full service with the dealer. The engineer said they tested in service and all fine.
- We will have to tow van to dealer for fix and pay the bill.
If anyone has advice on this do let us know we've only been caravanners for a year, it's a swift van. It seems a bit harsh after a service for us to get a fault not under warranty and have to pay for it. But we are not experienced enough to argue the point on this one.

go to the "consumer unit" (where all the fuses and breakers are, Is there any red LED showing next to the fuses??? if its red, that fuse has blown.
If not check the Brown 15amp fuse in the first position, thats the heating and hot water fuse,
I am assuming you have switched the Amber switch for the heating on????

Sorry I`m late with these ideas, only just seen the thread.....
If you lift up the seat slats above the water heater, you will see a black cover over the water tank, lift that off (be careful, small clips hold it in)
Under that cover there is another fuse, a clear glass normal type fuse.
Worth a try, good luck fella

Any joy HC ???

Sounds daft but I had a similar problem. Turned out that there was an isolating switch in the wardrobe to switch the panel off! Sometimes during a service they switch things off.
Another Truma error code was caused by trying to run the heating with the air duct outlet flaps closed.

We have a truma heater with on and off and a thermostat plus blown air if required. I must admit that reading about the Alde heating system and now truma I don't think I'll bother with an upgrade 😃 not that we were thinking of one anyway. I think making a solid leak proof etc van is far more important than making things complicated 😉

I found the new system far easier to operate after initial set up.

The van went back to the dealer who tested it and problem was not fuse (which was fine) but trip switch under boiler. Apparently, had this engineer been the one we spoke to on the phone when we were on site and the boiler was not working, he would of told us to check this. We live and learn. We know now where trip switch is located and what this error message is. We also know the name of the best engineer at the dealer's so we can go straight to him for technical problems rather than the others who' knowledge wasn't as good.
All fixed now for the next trip - which is good as the weather for the bank holiday is expected to be cold. Thanks for advice all.

Glad you got it sorted.

For that to trip ,I suggest when the c/van was serviced they did not switch off the water heater,and just drained the system, and when you plugged into the EHU ,the water heater/heater tripped as there was not any water in the system at the time

the truma Combi doesn't have a separate water heater....its a 'combi' unit. running the heating is fine with an empty boiler.
in Truma speak, this is known as 'winter mode' as many will have drained the system for winter yet wish to have warmth in the van without bothering to refill.
the red overheating button (trip switch) only activates if the heater is being used in 230v mode and, for some reason, the 12v supply is interrupted during operation or the after-run (cooling down) period.
(obviously, the fan is 12v as this allows the unit to run in gas-only mode).
perhaps the engineer turned the unit off too quickly, not allowing the unit to cool properly?
