The pump is "fitted" pushed into rubber grommets and will simply pull out. Get at it from the back and you can see what you have to get at. I can't recal how the wiring is fitted so it is proberbly just a plug in /out job. I have had mine out several times as it tends to run dry.. A good lubrication and it runs nicely once more.
Of course if the pump doesnot work you may find you have a lot of water left in the hose, so do be ready for a flood
