Advice on cleaning a pipe please

[poppym12]

It's time for cleaning the washer. I've run a hot wash with descaler thing, scrubbed out the dispenser drawer and hole but how do I thoroughly clean inside the pipe that runs from the dispenser drawer to the drum?

Run the longest, hottest wash with either bio powder or soda crystals inthe drawer as you would normally. You could also put some disinfectant in the conditioner section as the water doesn't reach temperature in cold fill machines until part way into the wash.

Thanks fudge. That didn't clean the bit I wanted so I took the drawer out and put soda crystals then boiling water into the hole. Think it's worked.
