There is a leaking hose connection to the pump in my dishwasher. I have tried silicone and a hose clamp but no no avail.
What can I do to fix this? Picture before the silicone, the corrosion is from the leaking wastewater.
I would start by cleaning up the corrosion and debris. If possible remove the hose/boot and clean any debris from the inside sealing surface. Inspect the hose for any cracks or holes. Looking at the photo the bottom clamp appears to be installed correctly. The upper hose appears to be installed too low. The clamp is squeezing the hose but not the pipe. The clamp should be against the shoulder/flange of the hose.
