Eh... I adored my IKEA kitchen and would get another now we’ve moved in a heartbeat if we moved... but all the appliances were crap. Light went on extractor fan almost immediately, oven started making a weird noise although still worked, dishwasher left awful residue taste in everything. I was so shocked as I really am ikeas biggest fan. But really don’t do it (I did it for ease and because they looked pretty together like the brochure). Also it was hard to sort out, Ikea batted us to whirlpool or whomever it is who makes them, was really hard to get through to them and gave up in end.
If you want an integrated dishwasher you are more or less obliged to buy it from Ikea as the "normal" integrated dishwashers can't open with the extra long Ikea door fronts. (They used to sell adaptor kits to convert regular dishwashers but no longer do.)
We got our dishwasher from IKEA for the reason mentioned above about door sizes. We really didn’t want to, but it was just way too much of a pita not to. In the end we were really happy with it. There did end up being a slight problem with it after a while, but it was repaired quickly and efficiently. I really wouldn’t worry about getting the dishwasher from them, it’s made by one of the big electrical companies anyway (Whirlpool maybe?) and at least with IKEA you get a long guarantee period and decent customer service!
I had a bad experience with an IKEA integrated dishwasher. Had to replace pump once in warranty then broke again after warranty expired - lasted under 3 years. Wasn't worth repair Also the top shelf of the dishwasher was the most annoying design ever and we constantly broke glasses and mugs that wouldn't sit right. Glad to see the back of it
The reviews vary a fair bit. The cheaper end tends not to be that good, but some of the mid range stuff does very well - the Smaklig hob, Kulinarisk pyrolitic oven and the stainless steel £250 microwave all get excellent reviews.
Coming back to reassure you really that actually the dishwasher wasn’t that bad on reflection, it was mostly extractor and oven. We hadn’t chosen top of the line for those as couldn’t afford it. I think you’ll be okay.
I had an Ikea kitchen and appliances installed in my last house in 2006, I don't live there any more but still own it as a BTL. Had a fan oven, integrated fridge and halogen hob fitted and as far as I know all are going strong 11 years later (I'm sure I'd hear fairly quickly if they weren't!).
We had all Ikea appliances except oven and microwave, for which we thought we’d go for something ‘better’ from John Lewis. Both JL things have been rubbish. All Ikea stuff, however, still going strong!
