Re: Only half the story
For £229, you can buy a perfectly good brand new dishwasher (even Which recommends Beko if you can't afford a Miele) which is probably quite a lot more efficient than your old one.
It will almost certainly break down after 5-6 years, though. At least ours did. Repair cost was quite similar to a new one, naturally. These things are a tough call - you cannot predict the reliability of a new machine, no matter what it costs. Even Mieles break down, and they don't offer a 10 year warranty on everything. (If you look closely at their prices, you can see that you're paying for just the extended warranty on some devices) So we have another Beko. Knock wood, it's been fine for 5 years and the drain pump that failed on the last one is an improved design.
