I have tracked down the source of a significant leak in my 12 year
old Bosch dishwasher. There's a worn O ring on the water inlet side
of things. It's a fairly chunky O ring about 2 cms wide.

Bosch still sell these, but annoyingly they charge around £25 for a
set of 4.

I don't think it's possible to silicone the joint. Any other
suggestions?

The machine has been used once or twice a day for 12 years, and I was
happily contemplating a new Bosch to replace it, but the price of
this simple spare has put me off.

Looks similar to the one I needed to replace on a Miele of similar age
- probably in a similar application where a solenoid valve connected
to the water softener mixer tank. Part was about 4 Euro from ebay, but
I was able to effect a temporary repair with some PTFE tape wound
round the shaft of the valve to make it a tighter fit:

In my case, the temporary repair is PTFE tape wound round the outside of
the O ring. I haven't worked out why the o ring shrank in the first
place. There are four of them, and only one has shrunk.

The bodge seems to be working, so I've put the machine back in place and
levelled it. I'll just see whether there is any water leaking in normal
use.

I've taken the opportunity to drill a 2mm hole in the sump. That'll let
small quantities of water drip out slowly but still stop it if there's a
significant flood.

Asking around various o ring stockists, this is a specialist size. So,
if I need one, I'll probably just have to pay the Bosch prices. There's
a guy offering a set on ebay for the knock down price of only £11.

Could you just cut one from some suitable thickness rubber sheet?
