There is the possibility of damage being caused if your dishwasher overflows into your garbage disposal. The following is a plan to prevent that from taking place:
Dishwashers and garbage disposals are designed, for the most part, to function independently of one another and not interfere with one another in any way. The units are typically installed in separate locations under the kitchen sink, one on top of the other, so that there is no risk of them colliding with one another if they were to become clogged.
However, if they are installed improperly, either by an inexperienced plumber or a homeowner, it is possible that one of the appliances will end up partially blocking access to the drain opening where the other appliance is supposed to go. In the event that this occurs, it is possible for one of the devices to cause a backup on the other device.
Incorrect installation is the most likely culprit when it comes to a garbage disposal becoming clogged with food debris from a dishwasher, but there are other possibilities as well. If you have the misfortune of living in an area that has extremely hard water, for example, bits of mineral buildup inside your plumbing system could create narrow spots that slow down the flow and give solids time to settle out.
If you don’t have the misfortune of living in an area that has extremely hard water, however, you should be fine. Unfortunately, when these clogging deposits are viewed under magnification, they can be mistaken for long hairs. This gives rise to the old wives’ tale that tiny ringlets get caught around moving drainpipes in sinks and tubs.
It is also possible for foreign objects, such as toys or plastic silverware, to make their way into your garbage disposal or washer and become lodged at some point along the way. This can be a frustrating experience. It is possible for either appliance to become clogged as a result of this, but it is more likely that the dishwasher will drain slowly or not at all without causing the kitchen to flood.
Keep in mind that the best course of action, in the event that you have reason to believe that either your garbage disposal or your dishwasher is causing a backup into the other unit, is to turn off both appliances and get in touch with a licensed plumber. Before you make any changes, it’s best to have a professional look at both devices to figure out which one is causing the problems with the other.
When something blocks access to the area where one machine drains into another, causing waste to become stuck and unable to exit in the appropriate manner, a garbage disposal can back up into a dishwasher.
The majority of the time, the problem is caused by improperly installed appliances; however, it is also possible for foreign objects, such as toys or plastic silverware, to become lodged inside either appliance. If you think there may be a clog, turn off both of the appliances in the kitchen and then call a plumber.
