Rotting dishwasher rack

[RJH]

Any tips on how best to deal with this:

(dishwasher wire rack plastic coating perished, rusting)

[Brian Reay]

Assuming you don't want to replace it...

Clean off loose rust & plastic.

Treat with 'Kurust'.

Coat in Epoxy- JB Weld is grey and is better at temperature- checking you get a good overlap and coverage.

have you ever tried doing that? I don't think you'd succeed

plastidip?

[Rob Morley]

That was my response too, but I wonder how far the corrosion has reached under the coating. It might be worth stripping it all, shot blasting and powder coating, rather than patching it up and have the patches fail.

Thanks - that looks the type of thing.

I was thinking in terms of cutting it back to good metal, then coating the exposed metal with maybe a primer followed by plastidip suggestion:

Goes to 93C, so should be OK.

[RJH]

Ah thanks, yes. £24 though. I'll have a go at mending first.

The fact they rust in the first place is a bit rubbish. It (Siemens mid range) is only about 5 years old and not had heavy use.

[The Natural Philosopher]

Dishwashers today have a service life of 3 years before they break and 5 years before they are BER.

Araldite applied in 2008 over rusting around a weld in our rack was still solid last night.

Grit blast all the plastic until the entire thing is bare rust free metal and have it re-dipped. But to be perfectly honest you'd do better to grit your teeth and buy a replacement.

Previous one lasted from 86 to 17, 31 years.

Is poor loading causing things to cut into the plastic coating in the first place?

[tabbypurr]

they tend to go on the outside of elbow shaped bends. Nothing hits them, the plastic just cracks up over time, and there it's least supported & most likely to peel. Better plastic needed, or maybe zinc dip coating.

Better make? No sign of this or any other problems on our 20 year old Miele dish washer.

[The Natural Philosopher]

You see. That was presumably made 36 years ago, before we joined the 'common market'

[The Natural Philosopher]

Todays miele dishwahsers are not a patch on old ones.

[tabbypurr]

Reliability is one of the things I like about some old appliances. 1930s on es are better made, probably only because the less successful 30s ones are long gone. A lot of 30s stuff suffers too much in the way of design issues but some's still good for today's world.

Really? People said that about our current one when we bought it 20 years ago.

Scrapyard, you might even get a fiver for it

Buy a washing up bowl at a poundshop

Then buy a new cabinet for the kitchen and fill it with all the extra crockery and cutlery you needed because you had a dishwasher
