Re: Diplomat ADP8525 dishwasher
Remove the two original O rings. There is not enough room to fit 2 of the same size on each nozzle so I fit a smaller thickness, smaller diameter one first then refit the original. Aim to get the retaining clip to catch tightly, so a bit of trial and error needed. Put a smear of washing up liquid on the original O rings so they will slide in the sockets easier and will compress better without the rubber sticking. For security, I zip-tie the catch lever in place so it cannot come adrift.
Hope that helps,
Steve.
