A non-draining dishwasher is a very common problem. We know that it doesn't seem simple when you are sitting with a ton of water and dirty dishers - but maybe these quick tips can make a difference.
- First check is underneath the sump entrance screen. This is located on the bottom of the dishwasher (on the inside). There are usually a couple of screws that you have to remove to peek in. Check in there for any crud or gook. There may be small pieces of glass so wear work gloves. Get all of the crap out of there.
- Many dishwashers have a self clean filter inside the basin, at the back of the dishwasher. The draining water must pass through a plunger in the self clean filter body. This can get clogged up and you may need a new one if it is twisted or distorted. The draining water must get past this. The filter can be easily removed from the inside to check to see if it is okay and the plunger will twist out of the self cleaning body so that you can check for distortion.
- The back flush valve is sometimes the culprit of draining problems. This can be viewed on the back of your dishwasher. All hoses between the the drain hose to the house plumbing should be checked for any type of restrictions.
- Newer dishwashers have a separate drain pump and motor. Older model dishwashers used a drain solenoid valve. If this solenoid fails, the dishwasher won’t drain and you will have to replace it. If the solenoid cannot pull in the plunger, the drain port will not open to allow the motor and pump assembly to drain the water out.
- Use a ohm meter to test the continuity of the solenoid coil. You should also test to see if it’s receiving voltage when the dishwasher is supposed to be draining.
