Hi does anyone know if there is certain way to take this out as I have twisted it anti clockwise and tried pulling it out like the old ones but the black piece that you hold to pull it out keeps coming off when i try to pull. I dont want to try too much force on it yet so any help greatly appreciated.
Cheers Steve yes that is what I am talking about its my first time coming across this type how does it work? The older ones were basically a pressure switch.Got it out yesterday exactly the way you said. The error code coming up is f04 there is a lot of muck in the filter and the sump would this be causing this.
