I think but am not 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} that a lot of Ikea appliances are whirlpool.If the 5year guarantee is for parts and labour it sounds like a good deal.However do check the guarantee carefully before you buy.
To add to my above post the guarantee on ikeas website does not make anything clear as to what is covered.Please double check with them and ask for a copy of the guarantee before you buy so you don’t get a surprise in the future.
