I purchased Elica chimney in october2017.Just after 6 months, the chimney is starting and stopping on its own.The matter was reported to Elica.Their after sale service is so poor, that even after 20 days, they have not fixed the issue.I was told PCB was not available.Now spare part is available, but their mechanic is making one excuse or another.I had horrible experience.I will never by Elica auto cleaning chimney again.
