What does extended warranty mean???????

<p>I bought dishwasher on 9 Jan 2014 with 2 yr guarantee and 3 yr extended warranty from Hirsch.In Dec 2015 I had a problem with the PC board. They fixed it. Same problem again on 26 April 2016. Again in May, which they fixed on 22 June 2016. Same problem 6 Sept 2016 which was finally fixed on 30 Oct 2016. Yesterday, 3 months later, the same problem AGAIN! I went to Hirsch shop in Strubens Valley and asked them to refund the money as obviously there is a factory fault with this machine. I told them that I will write to you if I don't hear from them today. They had to check with headoffice, but till now: NOTHING. I really don't know WHAT to do. Carry on till January 2019 with this problem every 3 months?? I have all 4 job nrs.</p>
