Options/recommendations for replacing failed Zappi

[NSS]

Hi all, long time no post, but I still loiter.

 

As the subject says, our Myenergi Zappi has failed (output failure error), irritatingly just 16 days out of warranty. They're offering to supply a recon unit "as a goodwill gesture" at a cost of £349 + VAT, but I'd have to arrange fitting myself. 

 

As those who remember me will know, electrics is a black art to me, so my questions are....

 

1) how easy would it be to swap out the old for new, ie does it need to be a specialist fitter or could any competent sparky do it?

 

2) should I be considering an alternative solution?

 

Thanks in advance for any advice 👍🏻

How old is it (what is the warranty period)

 

Replacing it with the same is the classic case of doing the same thing but hoping for a different result (the replacement lasts longer)  So I would not do that.  I would be asking this forum and others what alternative make has a proven record of lasting longer.

 

The fact they are offering you a refurb unit means they have been collecting dead ones and repairing them.  Personally I would be taking it apart to find out what has failed.

Hi Dave, how are you doing? The warranty was 3 years. The recon unit would be of the latest version, but I have similar concerns, hence my second question. 

 

I've spoken to the installer, who says he's come across this issue before and, in his experience, it's not something that can be easily (or economically) fixed. Online searches suggest it can sometimes be caused by a loose terminal or broken contactor, or a faulty relay, but I wouldn't have a clue what to look for, and even if I did I wouldn't have confidence in being able to safely dismantle and fix it.
