Re: reliable used dishwasher? Do they exist?
I’m a plumber and also do some minor domestic appliance repairs.
I can’t say if it’s been reliable, or not, but I installed a second hand dishwasher about 3 months ago.
2nd hand dishwashers often put in an appearance on Freecycle – http://www.freecycle.org/display.php?region=United{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d}20Kingdom. There’ll be a group near you.
Alternatively try a local LETS (Local Exchange And Trading Scheme) but you may have to pay a nominal joining fee. LETS, however, can be a nice little earner if you have some suitable skills and time to offer!
I believe any domestic appliance should outlast its warranty by a few months! It’s really luck of the draw. I’ve just replaced the brushes in the motor on a 25 year old washer/dryer (my own). I don’t recall ever having to do any repairs on it before. I can’t see it lasting another 25 years, though, so I’d better start saving for a new one!
