thanks for all your speedy replies -
we do all this already, we know its a hard water area of Thames Water
this dw is 6 years old now - it looks like new inside but the results are
increasingly disappointing
we use different tablets, capsules, liquid, salt, rinse aid every purchase,
whatever Waitrose have on offer,
the rotary arms still spin and the holes are clear and unblocked,
we use a variety of settings to suit and a cleaner once a month
the lower arm doesn’t reach too high though, as in one small deep
Prestige pan never looks as though it has seen water, requiring hand washing
the dw is never overloaded, which apparently is usually the cause of poor results
what is the average life on a dw before it begins to fade away and
become less efficient
the whole point of a dishwasher is to perform more efficiently than by hand
my OH opines that we are flogging a dead horse and should replace it which I
am resisting
Look out next for my requesting recommended dishwashers as reading this ^
I’m now wondering if I’m not answering my own question…
