Why is it???

When the Washing Machine starts to make the:

thumpa - - - thumpa - - - thumpa - - - THUMPA - - - WHANGA - WHANGA - WHANGA - WHANGA - WHANGA..WHANGA..WHANGA..WHANGA..

That it will suddenly **stop** after I have raced from the office, down the rickety basement stairs, and reached the machine???

I think the damn thing has it in for me....
