If you visit my website it means that your Morphy Richards steam generator is no working properly.
You can fix steam generator iron of other makers, they are similar to repair.
I am a qualified electrician, have fixed 100's of these irons and sold 100's of pumps.
First of all, make sure your iron is unplugged and cool.
At the bottom you will need to unscrew 5 screws, then split into halves.
The top half is attached to the bottom by wires at the switch end.
The water pump is placed between the boiler and water tank, a green item with 3 wires.
To disconnect wires you will need a screwdriver or something similar as there is protection on the connectors, won't come off easily. Need to push a middle of the connector to release it and then pull it.
Lift up white cable tie.
Move white rubber ring out of the black end of the pump.
Move white rubber ring out of the black plastic part of the pump.
Disconnect hose from white tower connected to the water tank.
Pull this hose through the white ring.
Put back on cable tie on the neutral connector of the pump.
Hold white plastic ring and pull off the pump, place new pump into that hose, but make sure you pushed to the end.
Place inlet hose back through white rubber ring and connect to white tower connected to the water tank.
Connect wires to the pump, make sure wires are away from holes where screw comes through.
The best way to put back cable tie on the white tower, pictured above.
Put back the whole base and test it.
