One of the worst companies ever for customer service, never again!! In December 2019, I had a Zanussi ZC166250XA delivered, via AO. Com. From that day on, the electrics tripped at various times of the day. It could happen during cooking, whilst watching tele, at lunchtime, even at three or four in the morning! This occurred everyday, and made our lives miserable and stressful! We started by unplugging all the electrical equipment, and plugging them back in, one by one, to see if one would trip the electric. Non of them did, so we called an electrician. He checked the wiring and electric current, which was fine, but concluded the cooker was introducing fault currents in the system! I immediately called AO.com whom were very apologetic, and were enthusiastic to fix my cooker. They informed Zanussi/Electrolux (They are many companies under the AEG umbrella), to arrange a repair. It took three engineers, to diagnose and fit three elements, (at separate times). The tripping stopped for just over a month, it was lovely to be able to cook hassle free. Not long after lockdown, the tripping started again. Obviously, not happy. Contacted Zanussi, whom arranged another engineer visit. He said the element had gone again. By this time, I wanted a replacement as they had already been replaced, and what if they continue needing replacing, even after the guarantee runs out? Zanussi, was having non of it and insisted a different engineer come out, which he did. He replaced the thermostat, tightened a few screws, a told me he was going to recommend a replacement! Hooray, finally, I thought! After a few days, I hadn't heard anything, so 'll I called the repairs office, who contacted the technical department of Zanussi. Yet again, they insisted another engineer visit! My family and I, were distraught with anguish, as the electric tripped whenever the cooker remained switched on, at the wall. We had to turn it off after use, but sometimes this would cause it to trip! The next engineer came, who had been twice before. He checked the cooker, and exclaimed he was scrapping it! He called 'Technical', whilst in my kitchen. The adviser, told him to ask an office member, to draw up the paperwork, and send it to them. Again, I thought it was going to be exchanged! The next day, I called the service office, who informed me the manufacturer, want to send the head engineer, this time! Not impressed, at all! This has been happening for six months! The head engineer, actually was two electricians. Neither of them found anything wrong, which was no surprise! I had the feeling, a while ago, that the manufacturer, did not believe that the cooker was the problem, so I filmed the fuse tripping, along with the cooker being switched on. I showed this to the electrician, who sent it to 'Technical'. I had to wait for a decision, again! The next day I called the service office, and was informed 'Technical,' wanted another part to be fitted, an earth leakage kit. Enough is enough! I called AO.com, who were wonderful, apologetic (unlike Zanussi), and they felt the problem had been going on too long! They offered me a refund, or exchange, and have collected the troublesome cooker already! What a difference in companies, one with excellent customer service, one with non! Bet you can't guess which one I would Not recommend, Zanussi, or any of it's sister companies. They have the same policies. I paid £607 for a cooker that caused us nothing but grief!
