I have a diplomat dishwasher which is working for a few moments then it flashes f4 and just beeps, I can stop this by pressing the right hand button but it stays on rinse and does not move on with the program?

Hi spoonie, F4 is a draining fault.The drain pump comes on at the start of a wash. If you can hear it and the sump is clear of water it may be the pressure switch at fault,it gives the same code sometimes.
This is on the right side of the sump and has a wiring plug on it.You push the holding peg away and the twist a quarter turn anti clockwise and pull. Be VERY careful as all edges of these machines are razor sharp.All the best.
