Dishwasher Door Locks
A door lock in a dishwasher is more of a latch and catch type of arrangement with the door lock as such usually referred to as the latch and the part on the body of the dishwasher being the latch. Usually the latch is the small protruding part at the very top of the dishwasher cabinet.
It is very, very rare for the catch to become faulty.
Far more common is the small electro-mechanical door lock or latch to fail as this is the moving part that does all the work.
The image to the right shows a typical door latch complete with the door microswitch.
How a Dishwasher Door Lock Works
For almost all the basic principal is the same, the door lock or latch is housed inside the door at the top (you’ll see a small hole in the top panel where it is) and in there the catch inserts into. Inside the small tongue will flip over on a simple spring to “lock” the door and hold it closed at the same time pressing on the microswitch to let the machine know that the door is closed and it is safe to run.
Common problems with these are that the just break up and don’t lock at all or come loose as the mounting points break and of course the small microswitch can also fail.
When this happens you will get the door not “locking” into place, you won’t feel that normal click as it engages and the dishwasher simple will not do anything.
This is as it is a safety feature, the dishwasher will not run if the door is not fully latched shut and the machine knows it is safe to operate.
Finding & Ordering Dishwasher Door Locks
Door locks are a most common part to change in their lives meaning that you will often find a replacement will be different from the lock originally fitted in terms of look.
Sometimes the fitting will also alter slightly.
It is therefore important to find and identify door locks using model and part numbers and not to try to identify visually in a good number of cases as, they will often not look the same.
This means also that all too often any numbers on the old locks are worthless when attempting to use them for identification purposes. Not always, but in most cases this will hold true.
You will find the most common dishwasher door locks in our spare part store but if you are at all unsure please ask us for help as we’re only too happy to find the correct door lock you need for you.
Compatible Door Locks
There are some dishwasher door locks that will have what we call pattern equivalent replacements. That is to say that they are not original manufacturer replacements.
This can be confusing and where we advise on a case by case basis as, while many so called “pattern”, “equivalent” or “compatible” spare parts are low cost knock off parts that often aren’t very good quality, there are often equally as many that are either as good as the original part or indeed are the original part, just without the original branding.
Using these can offer you considerable savings on a replacement dishwasher door lock and, be just as good.
Or advice out be to ask us for advise as often trying to fathom what one will be suitable can be a challenge for people that do not have the knowledge of parts that we do. usually when asked, if there is a compatible door lock that is decent quality we will tell you about both the original and compatible part when you ask us.
Fitting A Dishwasher Door Lock
Although there are variations on the theme, usually these are fairly easy to swap out.
The trick is to release the top facia panel from the door of the dishwasher, there’s no need to haul the machine out which is a bonus, especially on integrated dishwashers. However, on integrated dishwashers you will need to remove the front wooden door to get to it as you need to release the facia just as you would on a freestanding dishwasher.
If you play it clever though you can usually take out a half dozen screws around the top facia panel then flip that forward to get to the door lock, which is invariably held in place by two screws accessed from the inside of the stainless steel door panel.
Just as shown in this image.
Simply replace like for like, even if the design is a little different and put it all back together.
It’s as easy as that.
