Plumbing - I put the wrong soap in the dishwasher, now what?

What to do if the Wrong Soap was Used So you used dish soap instead of dishwasher soap? If you did, you know the result; lots and lots of soap suds that just won't stop. So what do you do? This is easy to fix, if you know what to do; and we do. First scoop out as much water as you can and dump it in the sink. Next add a cup or two of white vinegar and run the dishwasher for a short time. Now scoop out more water. The vinegar cuts the foaming action of the soap. You may have to repeat the process to eliminate the suds because some soapy water remains inside the pump and hoses. Also, if you poured it into the soap dispenser, wash that out by hand to get all the dish soap out. Source: AcmeHowTo.com
