How to repair or fix a Dishwasher if it doesn't drain

Hello,

Following a cycle, a small pool of clean water inside the tub is normal. An excessive amount of water means the pump isn't pumping water out properly, the drain hose isn't carrying it to the drain pipe, or the house's drain lines are backed up.

If dirty water spews from the air gap, the drain line is kinked or clogged. (If you've recently installed a garbage disposer, be sure the knockout plug for the dishwasher was removed when the connection was made; see your disposer instructions.)
1) Remove the cover from the air gap at the top of the sink (usually a short chrome domed cylinder that sits at the back of the sink), and, using a stiff wire, clean it out. Also check the entire length of the drain hose for kinks or blockages, especially at the drain connection to the disposer or drain line.2) Once the dishwasher is cool, shut off the power to it, and-if your dishwasher is made to allow this-remove the strainer, located under the bottom spray arm at the base of the cabinet (see illustration). Unscrew the hubcap, lift the spray arm off, and remove any clips that hold the strainer to get it out. Scrub it clean with a brush, then replace it.
3) Determine whether the sink trap or house drain line is clogged.
4) If the dishwasher still doesn't drain properly, the drain hose may be clogged or the drain valve may need replacement. You can check the drain hose for obstructions, but this sometimes involves pulling the dishwasher out from under your counter to access the hose, disconnecting the hose at both ends, and flushing it out with a faucet or garden hose or replacing it with a new hose.

Hi


Thanks for using FixYa. Dishwasher not draining properly or not draining at all issues can arise due to different reasons. Usually, these issues are related to kinked hoses, knocked out disposer unit (if connected with the dishwasher drain hose) & clogged drain pump & filter. Also note that dishwashers do not drain completely after a finished cycle and this is normal. Dishwashers are designed to leave some water in the unit to ensure that the heating element doesn’t overheat. If you suddenly begin to experience a large amount of water being retained in your dishwasher, you have a problem. Some of the most common reasons include that the drain hose isn’t working properly, the drain pump isn’t working correctly, or possibly there is a plumbing problem in your home’s drain lines. First check whether the drain is not clogged or blocked and the line is not kinked. Check all the hoses for blockages & also clean the air gap. If you have checked the drain hose and can’t locate the problem, then it is an issue with the drain pump of the dishwasher. Please do accept the solution if the issue is resolved or post a comment for further assistance.
