@Lesley Christie ,
Check the washing machine's control board for fuses mounted on the board. They may not look like what you think fuses should look like, so look for components with a designation beginning with F written on the board next to the component, e.g. F1
Usually the power for the pump comes via a relay or solid state switching device (not sure regarding your model if it is as shown above) mounted on the control board and it is protected by a fuse also mounted on the board.
You will probably need an Ohmmeter to measure the fuse for continuity as you may not be able to visually verify that it is OK or not. Measure the fuse with the power totally disconnected from the machine. It should measure 0 (zero) Ohms i.e. a short circuit
Hopefully the fuse specifications will be printed on the fuse case so if it is blown you know what value fuse to get.
