ᐅ NOVELAN LAD9 Heat Pump Error 704

Good morning everyone,

our heat pump, brand Novelan, model LAD9, has been showing error 704 for six weeks now, always when it gets cold outside. More precisely, this error occurs whenever the temperature drops below freezing, indicating a hot gas fault.

We have called the manufacturer many times, but currently they cannot supply the compressor, which according to them needs to be replaced.

The error keeps recurring, and the manufacturer provides no information at all—also no response to my question about what happens if our system suffers further damage due to the delivery delay. Therefore, my question to you is: do you know what rights we have in this situation? The system is 3.5 years old.

The only thing customer service mentioned over the phone is that we could switch to the electric heating element. That means heating with electricity... and when I asked about the high electricity bills we would have to pay, of course, I did not get any answer. Great service...

Thanks and best regards,
Ina

Clearly very frustrating, but the warranty period has expired, unless you took out an extension?

How much is the replacement supposed to cost?

Hello,
does the error still only occur with hot water preparation or now also with heating?
Regards

No one has come out yet, so I have no idea about the costs. I spoke to a technician on the phone who, luckily, was knowledgeable. He said they usually offer a five-year warranty on anything related to the refrigerant. I might be lucky, and he told me I could probably relax about that. Still, it’s just really annoying…
I’ve also switched to a second heat source for hot water now…

Ok, strange. Just before Christmas, I also had a problem with our heat pump from AIT, and someone from the factory service was here within 3 or 4 days.

I would definitely recommend having a technician come out; maybe you’re lucky and it’s just a minor issue.

Hi Daniel,
yes, exactly, still only during hot water preparation
