If you can remove cover (without flooding the floor) it should look like this

If removing cover risk flooding floor you maybe able bung the drain from the drum (to left - red square) temporarily so you can inspect pump.

Remove anything that shouldn't be there (coins/ fluff...)

Check the plastic blades spin (circled in yellow) - there should be one point in the rotation that's pushing against magnet

If you feel above the plastic blades you should be able to check that drain pipe exit is clear (small circular finger size hole). If you feel to the left in front of pump (Red Square) you can check water inlet from drum.

If you turn the machine on and start a spin and drain cycle with cover of you should see white plastic blades spinning. (Best not to stick your figure in to check!)
