Washing up liquid in dishwasher....

[bennyboydurham]

My wife, in a top notch display of brain fartery has used fairy liquid in the dishwasher as we'd run out of tablets. Result: my kitchen looks like some kid's foam party and the dishwasher has a suddy beard. Also it won't stop cycling! It's been on for 12 hours now and is still full of foam. Somehow it's my fault because I didn't buy replacements at Sainsburys.

What can I do, PHers?
