Hi: Looking at the spares shop there are 2 different pumps listed for your machine. If you email spares@ukwhitegoods.co.uk giving the serial No as well if possible, Dave will be able to tell you which 1 you need & supply it at a good price.

Thanks. I checked the images and this looks like the right one; and if it’s not I’ll be posting next weekend trying to work out how to change the base ;-).
