Turn Washing machine off at 13amp socket switch

Pull off lower front cover

Have a big towel/rag to hand

If you have something about cork size or bigger the can be squashed down to bung a 15mm whole to stop water escaping this might be useful

If you can top washing machine backwards and rest front on some block of wood so you can get a tray under the front, that might help too.

Unscrew drain pump cover

As cover unscrews water will start to flow out.... NOTE: This could be a cup full, or could be entire drum contents

If flow subsides after quicktly (after ~5 seconds) and there is still water in the drum then it should be save to remove cover completely without flooding floor. IF NOT SCREW COVER BACK IN QUICK
