Engineer had to come out three times. The margin on parts is extortionate. First visit the engineer was here for about 5mins without actually looking inside the appliance (an oven) to basically confirm my description of the issue. Ordered wrong parts which was ascertained on the second visit when he actually opened the appliance up, so third visit for the fix, of which I am not impressed by end result (CPU board with clock display which is now a bit wonky). Oh and I am still waiting refund for the parts I unnecessarily paid for (which were c.50% more expensive than if I went direct to manufacturer). In short, looked like good value, but underlying it cost me more than a new oven with an underwhelming fix. I suppose I can still cook with it, but I won't be using them again.
