This is one of the most frustrating faults, especially because washing machine doors almost never jam shut before the washing starts. No, they normally wait until they’ve finished washing your clothing, and then they decide to stay closed. Can be rather annoying…So here are some causes and a simple manual to solve the problem in a DIY way.
1. The door could stay jammed even when water has been properly pumped out if there is a faulty pressure switch or a blockage in the pressure system, as it could be trapping the air that's operating the door lock.
2. On some machines if the pressure switch doesn’t reset, it keeps the door lock energized. Turning off the machine at the mains should allow the door lock to cool down and open after a few minutes.
3. Interlocks can take some time to release at the end of the cycle, so be patient. The most common cause is water left in machine. Try running a spin/drain cycle. If this fails, the machine can be drained by placing the drain hose lower than the drum (into a bucket or tray).
4. The door interlock has simply jammed. Call an engineer.
5. The door catch, handle, or some part of the door catch mechanism is broken and not opening the door.

Never ever use force!
Call a repair man to fix your machine and help you rescue the captured clothes, hopefully as quickly as possible. Then wash again with Ariel detergent to get your great results back.
