Why Is My Commercial Dishwasher Not Draining?
For those who work in a restaurant, commercial-grade dishwashers are one of the greatest luxuries out there. So when your dishwasher stops functioning like it should, it may seem like the end of the world. Not to worry though — we’re here to provide you with helpful information on how to troubleshoot your dishwasher, as well as tips on how to repair it so that you don’t have to resort to hand-washing dishes.
3 Reasons Why Your Dishwasher is Not Draining
Commercial-grade dishwasher can stop draining for a variety of reasons, but three common culprits include:
1. The filter is clogged.
2. The drain lines are backed up.
3. The drain valve is malfunctioning.

To find out why your dishwasher isn’t draining you’ll have to do some investigating. If the filter is clogged, you will have to locate the filter (generally at the bottom of the tub, by the base of the lower arm, or at the back) and clear any debris around it. Usually the cage needs to be unscrewed before you can remove it. Once removed you can clean the filter of anything clogging it.
If the sink is backing up, the drain is most likely clogged. You will need to turn off the power either by turning off the breaker or unplugging the dishwasher. Remove the panel by the floor to reveal the drain hose (the one with ridges) and disconnect it from the pump. Straighten it out to get any kinks out before you clear the inside of any debris. You can then replace it and turn the power on to an unclogged drain line.
The drain valve plays an important role in keeping your dish water from draining back into the dishwasher. Push on the valve bracket to make sure it is moving freely and isn’t stuck. If it is frozen then you will need to replace it. Again, making sure to do so with the power supply off.
If Troubleshooting Dishwasher Doesn’t Work
If your dishwasher is still not draining after cycles and you have troubleshot all of the above, then it’s time to call a professional to come take a look at it. The problem could mean that you need to replace your dishwasher or the technician can pinpoint the exact cause.
