Dishwasher Drains Into the Sink
A blocked drainage hose is the primary cause behind dishwasher draining into the sink. Fixing this problem is fairly simple, so by all means you should try and resolve the problem yourself before you call a repair person out to perform costly repairs.
Cleaning the dishwasher drain is the easiest way to solve the draining into the sink problem, but it must be done properly or it can create more problems than it solves.
Using one of the high-powered heavy-duty drain cleaners can actually corrode or damage the hose. This is because the chemicals cause the cleaning agent to go through the system too fast. A better way to solve the problem is to manually clean out the drain. This will prevent damage to the hose, and it should solve all the drainage issues. Even though it may be a bit messy to clean out the drain this way, just think of the money you will save because you do not have to call a dishwasher repair professional.
A leaky dishwasher is basically either going to be caused by a problem with loading or a bad door seal. Many people do not realize how many problems they cause when they overload their dishwasher. An overloaded dishwasher almost always blocks water jets, which in turn lead to more serious problems. The first thing that you need to do if you notice that your dishwasher is leaking is to put less dishes in the dishwasher.
By only loading the dishwasher to the point recommended by the manufacturer you can ensure that an overload is not the problem. The door seal issue is also pretty simple to repair. You can feel the rubber seal around the door to see if it is damaged or irregular. If you find that it does have an issue you can go to your local appliance repair store to get a replacement seal. Damaged dishwasher door seals need to be replaced immediately. If you cannot find the part that you need at the store you can go online to find it.
Dishwasher Will Not Drain
If a dishwasher will not drain it is usually due to a blocked drainpipe or a clogged sink trap. Both of these problems can also be solved without the aid of a dishwasher repair specialist. Clearing the blockage out with a snake is usually sufficient to get everything back in working order. If simply snaking the drain does not solve the problem you may need to replace the drain hose. You do not have to use a drain hose that is the exact same brand as your dishwasher. As long as the hose fits you can use a drain hose made by any manufacturer. Be sure to follow the instructions in the user manual when replacing the drain hose in order to ensure that you replace it properly.
