Our dishwasher is kaputt. Couldn't close the door and the lights don't go on (weird). I suspect it is as old as the house - 12 yrs. I guess I could call an engineer but I reckon it would be at least £50 just for the call out, and considering how old it is, it should probably be replaced anyway. We need something full sized and integrated with a good quick wash function. I wouldn't like to spend over £500 although can go higher if it's worth it. Also, where's best for warranty, installation and recycling the old one? TIA!
