The Model of my Fisher Paykel is Nautilus 87605 or MSM 413291 F.P 920, the dishwasher shows F1 and beeps has not been washing clean for a while, I think it might be a blockage in the pipe. What to do.
Many thanks.

Wrong it is not a blockage. F1 means that there is water leaking down under & the flood switch has activated that is why you can hear the drain pump running continuously. You have to turn off power then remove the service panel below the door & the 2nd panel behind it. Then through the access hole you can get in with a sponge & a hairdryer to completely dry the bottom tray. You will then need to find out how the water got in there. It must have a leak somewhere. One common cause of leaks is the top basket rollers. Use a screwdriver & check that they are all tight. Once it is dry down under the F1 will go away.
