Samsung Vivace AQV12VBAN

[djordjevic]

Hi, guys!

I'm new to this forum. I have googled every possible corner of the web and then I found you. I'm having trouble with my Samsung air-con. It's brand-new, well, two weeks old. Since the second day of operation, I had gotten the E5-54 error. I had the repairman in who filled the outer unit with gas, as there appeared to have been a gas leakage. OK, the unit then worked for a few days, then the same problem appeared all over again. I called the repairman and this time he tore the inner unit apart. The guys that installed it obviously had not fitted the gas line screws tight enough and as a result the inner unit was leaking gas as well. To top it off, even the condense-dispensing hose fell off. He mended everything, filled the outer unit with gas once again, measured everything up, and got the air-con up and running again. My girlfriend nad I went to lunch only to find the air-con malfunctioning again. I decided to pull out the circuit breaker and reset the air-con. It then restarted normally and worked for about half an hour when, once again, it stopped. The air that was blowing out of the AC seemed to be cool, so I'm suspecting no gas leakage this time. Oh, yeah, then it presented a new error code - E4-69. The warranty is still intact, so even if there is no way to fix this thing, I shall request a new unit be brought and installed. The thing is, I lost confidence in the machine totally. Can anyone offer any advice on my turmoil? I'd be really glad.

Thanks in advance and best regards from Slovenia, Dejan

hi,your new error code is dc-link voltage sensor error,it looks like a plug on pcb board is loose,check all jack plugs on board,failing that email superswill or as we know him mr.samsung.all the best

[djordjevic]

Okay, thanks. Will try. Should have gone for Daikin or Coolwex, I suppose now.

As lee says your new error code will more than likely caused by a lose jack plug on the Outdoor PCB but id check all PCB connections due to the number of times this system has been stripped.

with a view on what Ive highlighted,have you lost confidence with the machine or the INSTALL? is it the units fault you have let down by a poor install? any make,model and size of A/C is only ever as good as its design,install and maintenance

such kind words (you would never guess your almost ready for me at sheff) :p

[djordjevic]

Loss of confidence is very relative. :) To be honest, the guys that installed it were obviously total analphabets. At least that is my oppinion since yesterday's overhaul. The repairman truly had to fix multiple issues, fixed every screw, checked it with soap fluid multiple times while measuring the outer unit with a barometer of some sort. It all worked fine. Now the inner unit works for, let's say, 30 minutes at a time, than shuts down and gives me the e5-54 error. I turn it off and turn it on again, since it is truly hot in the apartment and working in such conditions are utter hell. Now I'm thinking what could be wrong for the machine to shut itself off almost by schedule. A failsafe of some kind, perhaps?

E554 means TOTAL LOSS OF REFRIGERANT ! ! ! ! !

sounds like this will be a really painful experience for you,iam taking you have paid the Muppet's?

[djordjevic]

Hmm. What did you mean by Muppets? If it is really the case of missing refrigerant, then I am willing to bet there is a more serious issue with the outer unit, since the pipes and the hook-ups have been thoroughly checked. Damnit, I think I am going to have quite a fight with the sales/maintenance department of the seller.

muppets (idiots),as in the people who put the system in

[djordjevic]

Oh, thanks for the clarification. Muppets were included in the price (substracted aproximately 150 € - a lower fee, 'cause we had a pre-existing installation - condense dispensing tube, electricity feed and a drilled hole for the air-con wiring). Say, in your oppinion, will it be possible to repair my unit or should I outright demand a new unit, perhaps even insist on replacing my current one with a similar model from Daikin (at the cost of the seller, off course - some reparations must be made)?

all depends where the leak is,if its on the pipe work the it can be repaired but if it on a condensing coil,id ask for a replacement unit at no cost to you nor should there be after the initial cost of install for any of these works

[djordjevic]

Thanks for all the info. I shall keep you posted about future developments.

[djordjevic]

Today I talked to the seller and they said the unit will be replaced as soon as possible. In the meantime I got a call from my mother, who happened to be visiting some relatives in Serbia. They too bought a samsung air-condition, but were - get this - warned by the seller there that the vivace series is seriously faulty and that customers are having troubles with it, so they went with a simpler air-con by samsung and it works just fine. The repairman said to me the other day that some other people have the same e5-54 issue. The air-con cools but shuts down on a regular basis. As I am writing this short piece, the air-con is seroiusly cooling down the place, however, I presume it will shut down in ten minutes or so. So, coupled with the things I already know, I seriously advice against buying this model. I am contemplating asking the seller to swap my vivace for the slightly oricier mont blanc model. At their cost, obviuosly, to compensate for the nerves I lost in these tropic weather. :) As I am writing this, I already had to turn the damn thing on again - yep, you guessed right, e5-54.

Update. Today I had the repairman in for the third time. He checked the gas connections and added about 300 g of gas, even though it wasn't necessary. However, the unit seems to be fully-functional now. It has been operating since 17h and no breakdowns yet (knocking on wood). Let's hope it lasts this time.

my fingers are crossed for you

Bought my AQV12VBAN in May. Has been working fine without a fault ever since.

Until today. Power outage happened in the afternoon. The display started blinking. I unpluged/pluged the unit. No help.

I let the unit "cool down" hoping it will return to normal.

I googled, and found this site. I learned how to enter codes.

I used: 07 C7 70 17 52 60, and the unit reset sucessfully. But the outer unit would not turn on.

I tried: 05 47 77 12 52 1D.

The outer unit still did not start.

I unplugged the unit, and when I plugged it back in the display read E1-85.

Stumped.

Any ideas??? It's Friday. No repairs until Monday... It's HOT!!!

The compressor must to be checked it might of damaged a p.c.b. or it is burned out itself.

[Electrocoolman]

Try the code

05 47 77 17 52 1D

[zoranb]

I donwloaded the Service manual and entered the code shown there: 05 47 77 17 52 1D (thanks Electrocoolman!)

Anyway, the outer unit does not come on in any mode. The fan spins, but that't one expensive ventilator...

I can turn on/off the unit with the remote control, but when I unpulg it/plug it in the mains the unit reads E1-85 again.

Interestingly enough, the code doesn't show anywhere in the Service Manual.

My room temp is up to 31°C, and I still have this afternoon and tomorrow to go through...

*sigh* I'm starting NOT liking this unit seriously!

I just checked the wiring of my indoor/outood unit and there's something strange.

The wire connecting the unit is a 5 lead wire, but only 3 wires are connected:

1 st wire: N1 indoor - N1 outdoor
2nd wire: 1 indoor - 1 outdoor
3rd wire: 2 indoor - 2 outdoor

The other to wires (including the earth) are cut off at both ends and not connected to anything.

Correct me if I'm wrong, but shouldn't the earth wire be connected to the outdoor unit earth outside and earth connection on the indoor unit?

Now that I think of it, my a/c is connected to the mains to the same socket as my computer speakers, and I found it odd that whenever the outdoor unit switches on, I get interference on my speakers...

Any ideas?

Hi Nike,
Is it possible to have a translation for those who do not understand Croatian!

Of course, sorry!
I just gave him link to Croatian discussion newsgroup for this thematic! Therefore, I meant that there is no need to translation!;)

Hello there all. As previously allready said by other members this seems to be the only forum in the net dealing with this problem. I have recently bought two Samsung A/C one AQV09A and one AQV12A. The AQV09A from the first moment gave me an E4 69 error after 4h of working approximately. Then if you swithc it off and on it works well for another 4-6 hours and then crashes again. The techinian came and changed the board of the outer unit. When he first switched on the A/C gave an E5 56 error but then seemed to work OK. After a couple of days the A/C gave again an E4 69 error. I called them again and they said that they will replace again the outer and the inner board. Unfortunately today the AQV12A A/C gave also the E4 69 error. Any ideas about that will be appreciated. I thought that maybe i have a voltage problem or the installer did something wrong to both units or the Samsung series is faulty! I have called them again and informed them about the fact that now i have two A/C with the E4 69 error and they said that they will fix it. To tell you the truth i do not trust their repair ability so i am asking for second opinions. Thank you in advance and keep up the good work.

Damn, I have the same configuration of A/Cs and on the second day the AQV09A gave the same error. I called not two hours ago and Im still waiting for the rapair guys answer. I hope my 12 will not have the same problems as yours, but as soon as my 09 is fixed I'll share my knowledge. Since I live in Bulgaria, maybe our tehnicians have some other methods so you may be getting the desired alternate resolution:)

[CDevel]

Update from my story!
Well i have managed to claim and get full change of the AQV09A system. So they took it back and they brought me a brand new. I only wish that is not from the same delivery that included the faulty boards. As far as the AQV12A unit i still wait them to replace both boards inner and outer, and will see in near future what we will happen. Too pity that now is quite chilly here and there is no need for A/C to give them a good try...Speak soon Bye

[Brian_UK]

CDevel, thank you for the update and good luck with the second one.
