    Default Dishwasher not draining properly

    Hello, I recently successfully removed my busted garbage disposal and replaced it with pvc pipe. That went well, and was hoping it might have solved my dishwasher draining issue. Unfortunately it did not.

    There are two problems. the first is that while washing the dishes, the washer fills up and water splashes out, making a big puddle in the kitchen. The second is that once the dishwashing is complete, there is still a good bit of the water left in the bottom. If I don't remove the dishes immediately, it seems to "evaporate" onto them and make them slimy.

    When I set the dial to "rinse", the dishwasher will drain out completely, and then start a rinse cycle, so I don't think it's the pump itself, since it's capable of draining. It just doesn't seem to do it when it should.

    Anyone know what the likely culprit is?

    thanks!

    As far as wash quality, make sure that the water at the tap is VERY HOT before starting a wash cycle. Dishwasher detergents do not work in cool or warm water...it needs to be HOT. Many newer DW have a preheat function...use that if available. Also, studies show that most peope use TOO much detergent. Also, the new "envirnmental friendly" detergents are crapola!

    Now, it sounds like the fill float may have a problem and you are getting too much water in the wash cycle.

    hmm any troubleshooting recommendations? I know where the float is, should I try tapping on it?

    thanks!

    Sounds like the troubleshooting recommendations he made were to try a load it with either the right amount of detergent or maybe even none just to rule it out. Also, run the water at the faucet until it's hot and then start the dishwasher.

    My first run was without any detergent, and it still overflowed and didn't drain all the way. The water was VERY hot =(

    I'm not even testing it with dishes right now though, I just want to find a way to make it drain properly while washing to avoid flooding

    thanks =)

    This is a plumbing forum and the problem is not in your plumbing. Your dishwasher is at fault.
