Our Miele Induction Hob developed a fault(ERR040). Long story, short. We paid for their Fixed Price Repair. Two visits from Miele Technician, several parts changed. Fault persisted. At which point the Hob was deemed, by the Miele Technician, as beyond repair. New hob sourced, when our electrician came to fit it he found the original Miele Hob had lose connections at the isolator switch (factory fitted cables between Hob & switch). These were tightened & the fault cleared itself! We now have a serviceable Hob & a spare Hob! This should surely have been tested by their technician, before he started fitting expensive parts? Reported this to Miele; “Our Technicians are not electrically trained”!!!! They refused to refund the full call out charge. Untrained Technicians & poor customer service!
