I have a similar situation right now. Washing machine is leaking when load is anything bigger than light load. Initial guarantee claim to Whirlpool was sent 8 weeks ago. It's dead, no response from anyone.
Under consumer rights shop should refund, but claim is without response for 3 weeks (14 calendar days is upper limit according to EU law + local regulations).
Today I was supposed to contact the lawyer, but I figured out that f** this s**. It's weeks of legal battle over 300€. They won. Stress enough isn't worth it.
Oven is a different thing though, as I don't think it's as essential as washing machine (and dragging clothes every week for washing).
Maybe I should file a claim to refund after it was made, but it's still a net loss. Lesson learned: stay away from manufacturer Whirlpool, don't ever spend a dime on a shop and live on.
