I have just done the diaphragm change. soo here we go.
Firstly i would just like to start by saying these instructions are fairly universal for most pumps.
Warning always unplug electricals before operating on them!!! pumps are very safe to maintain IF they are unplugged!
Take off the feet and cover always a good start haha

The diaphragms are located under the black casing (see pic below) ,Also an option is to grab the "full repair kit" for your pump which also includes valves and other bits (sold at some hydro shops or pump stores,ebay etc.
I was fairly sure i didnt need them for this job so i just grabbed the diaphragms. undo the screws, holding the black casing to the heatsink.

Under the black casing is another case which contains the diaphragms (be careful not to loose anything)

Next undo the spindle nut. (see the diaphram its the big circular black thing in the casing)

So once the nuts off we can pull off the black diaphragm casing containing the diaphragm.. whilst being careful not to damage the fragile thin washers covering the front and backside of the diaphragm

Cant see much damage except the holes look to big and there's some wear and tear therefore probably loose..
out with the old in with the new

Carefully reassemble diaphragms and casings.
