Ok... Killed might be an exaggeration.
Yesterday I went to open the dishwasher door at the end of the cycle and splosh! A lake of soapy water splashed out onto the floor. That was a surprise because even when running you can open the door without any water escaping. A blocked drain pump quickly became apparent as the cause and as it's a 10 year old dishwasher, I wasn't hopeful of it being easy to fix.
To cut a short story even shorter, the cause of the blockage turned out to be 2 cardamon pods and a blade of star anise. I've never knowingly put plates into the dishwasher with whole spices still on them, but one by one those little blighters have found their way in there and built up a blockage. Curry eating dishwasher owners beware! ;D
