Thanks. I have now tried cleaning the chamber (it was not obstructed) but this has not solved the problem. Also I have checked the water level as Mike has suggested - the water only reaches 2/3rds or 3/4 of the paddle. The machine always used to work perfectly - plenty of water and easily able to dissolve two tablets. So something is definitely wrong now - whilst some water gets in, enough does not and it is worse when there are clothes in it (presumably because the clothes soak up the little water that does come in). If there is supposed to be a second fill (to top up the water once the clothes have absorbed some) I'd guess this is not happening. Might that be it? If so, can you advise if this is likely to be connected with the pressure switch, or might it be the controller? Thanks again for your help!
