Why a dishwasher won’t drain

Dishwasher Won't drain

Dishwasher Won’t Drain – The Dishwasher is a wonderful invention and kitchen appliance that makes life just a little easier, until all of a sudden the dishwasher won’t drain the water and you are effectively left with a flooded dishwasher. As with any electrical appliance that we become dependent on, it is very frustrating as it the cause is not always obvious. However, before you go looking for someone to visit your home to perform a dishwasher repair it is wise to try and identify what the dishwasher problems might be yourself.


Discovering dishwasher problems

There are many things that can go wrong and be the cause of a flooded dishwasher and by adopting a simple step-by-step approach you can narrow down the root cause and find out why your dishwasher won’t drain. The first step should be to check the electrics – most dishwasher units have a power on indicator light, if this is showing as “on”, then this is not the problem, what do you do now? Here is a list of common dishwasher problems in a logical sequence so you can eliminate the potential reasons as to why the dishwasher won’t drain.


•    Check the external drainage system – Somewhere between your kitchen and the main water relief system, somewhere on your property, there will be a small inspection chamber where you can open the cover and check it is not full of water. If it is full of water, clear it and train to drain the dishwasher again.
•    Check the connecting hose – If your dishwasher hose is connected to your internal plumbing you need to carefully detach it from the system, place a large bowl or bucket under the connection point and remove the hose. If no water is released you can replace the pipe. If some water does come out, the “downstream” waste water pipes may be blocked.


If neither of the above two produces a result, then you have isolated the dishwasher problems to the dishwasher itself.


Machine based problem that mean a dishwasher won’t drain.
One of the most common causes of a flooded dishwasher is the actual drainage from the dishwasher. There is a mesh that is place over the outlet pipe and this can get clogged with bits of food that have been left on the plates etc.


Another, but less common cause is the pump may have broken down, in which case you will need to get someone to visit to undertake a dishwasher repair.

Your dishwasher won’t drain, how can you fix it? This is a common question that arises and it is one of the common dishwasher problems. In all probability the root cause is something simple but no less frustrating. If you can establish that the dishwasher problems are related directly to the dishwasher and not the electrical connection or external waste water drain it is possible to drain a flooded dishwasher manually and hopefully avoiding any dishwasher repair bills.

Here are the steps to take to manually drain a flooded dishwasher

•    The first step and most importantly is to disconnect the power source to isolate the dishwasher and prevent any possibility of an electric shock.

•    Leave the dishwasher for at least 15-20 minutes so that the hot water inside has a chance to cool down. The last thing you want is scalding hot water pouring out of your flooded dishwasher and on to your arms or legs, even worse a Childs! If you think the water is still too hot after this time, leave it longer until you are happy that the temperature is low enough to deal with.

•    Place towels all around (where possible) the flooded dishwasher unit and perhaps have a mop and bucket on standby depending on how much water you are expecting to be released.

•    Open the door and let the water spill from the dishwasher.

•    Once the water has stopped pouring from the dishwasher you can pull out the lower dishwasher rack and remove any dishes that are inside the rack. Once the rack is empty, put it to one side and out of the way.

•    Remove any remaining water inside the dishwasher by scooping it out with a plastic cup, followed by mopping up any further traces of water with a sponge.


Having completed these steps you still need to identify what the dishwasher problems were in the first place. The chances are it was the outlet drain that was clogged up with bits of food from the plates, bowls and cutlery. On top of the outlet there is usually a small mesh basket that is included to catch such items, check this, clean it thoroughly and replace.


You can now run the dishwasher again to check that it does drain properly before you use it for actually washing your dishes again.

There are not many more frustrating things in the home than finding out your dishwasher won’t drain. The chances are that the last thing you want is an expensive dishwasher repair bill being presented, so the option is to try and fix it yourself. In most cases this is an easy job, although a little time consuming, as there is not much that can actually go wrong and create dishwasher problems.


A flooded dishwasher is not really a lot of fun, and more often than not happens at the most inconvenient of moments, but what can you do in the events of a flooded dishwasher? There are some very easy steps that you can take to find the source of your dishwasher problems that will only take a few minutes and they help to identify if it really is the dishwasher at fault or not.


When your dishwasher won’t drain, the first thing to do is to ensure the power supply to the dishwasher is “on”. If it is, then this is not the problem. Disconnect the power supply and venture out in to the garden and inspect the waste water chamber that collects the water from the house before it runs in to the main sewers. If this chamber is not blocked then it is almost certain that your flooded dishwasher problems are confined to the dishwasher alone.


When you return to the house you need to think about opening the dishwasher but take care to not spill hot water over you. It is wise to leave it to cool down for a while, maybe 20 minutes. While you are waiting for the water to go colder, place some towels on the floor next to the machine and when ready open the dishwasher door to release the water.


Once all the water has been removed, check the small filter at the outlet and if it is full of food stuff, clean it and replace. Your dishwasher problems should have been resolved with this action. However, if the filter is not blocked then you may have a problem with the dishwasher pump, which unfortunately may mean hiring a dishwasher repair expert and an eventual dishwasher repair bill.


Once you dishwasher problems have been fixed, ensure you perform regular maintenance on your machine by cleaning the filter, maybe 2 or 3 times a week. It also helps if you remove excess food waste of the plates and cutlery before placing them in the dishwasher.
