Here’s a tip for washing machines and tumble dryers and possibly dishwashers too. If you ever need to call an engineer (particularly if under guarantee) or need to find a spare part for it you will need to use the model number, serial number, and in the case of many makes some other special numbers printed on the rating plate.
This would be impossible if the fault you are experiencing happens to be that the door is jammed shut because these numbers are usually found round the back of the door. Make a note of them now, take a photo of them or write them down. The numbers are sometime duplicated on the back but it can be equally impossible to pull a washing machine out if it’s tightly fitted in a kitchen and the door is jammed shut.
Sometimes the numbers can also be behind the pump filter door flap or even behind the kick plate strip at the bottom of the front of the machine.
