Your Dishwasher's Spray Arm
The Dishwasher Spray Arm
The spray arm is a critical component in your dishwasher, with it being the main part responsible for the quality of the wash. Its main job is - of course - to spray water and detergent over the contents, and into all corners of the machine, leaving your plates, pans, and cutlery free of dirt and grime.
How Does It Work?
Water is pumped into the spray arm at a high pressure through inputs that are all watertight. This means the water can only be deposited into the machine through the holes in the spray arms. Water forced out the spray holes at an angle ensures water reaches all corners of the dishwasher. Sufficient pressure is needed also to ensure a good clean, the force of the water allowing the dirt on your dishes to be cleared efficiently.
Does Your Spray Arm Need Replacing?
Most commonly, your spray arm can get clogged with scraps of food, plastic, or even broken glass which has entered the machine. If blocked, this could affect the quality of wash, disrupting the flow of water. The easiest way to detect if your spray arm needs attention is to check if your dishes are not coming out clean. If blocked, take out the spray arm and give it a good clean to try and clear any debris to allow the arm to do its job.
Another occasion you may need to replace it is if there are cracks or breakages in the arm itself. If the spray arm system is not water tight, then pressure will be lost. This means water will not be sprayed over the plates and dishes with adequate force, therefore your dishwasher may not clean the items properly. Cracks in the plastic arms are not fixable, and therefore a replacement part is the only solution.
Replacing Your Spray Arm
This crucial part of your dishwasher is surprisingly simple to replace, and can be done in just 3 simple steps:
Turn the waterproof nut that is located underneath the spray arm counter-clockwise to loosen the component. This will allow you to remove the old spray arm.
Place the new arm in place then simply tighten the new spray arm by turning the nut clockwise.
Some models have a spray arm with a click system. These are even simpler to replace, and you just need to click the arm into place.
Here are some tips on how you can look after your spray arm:
Make sure you load your dishwasher correctly, leaving enough space between items so that water can do its job and to prevent the spray arms becoming clogged with dirt.
The pressure of the spray arm can sometimes be increased also. You can check the manual on how to achieve this. This may improve the quality of clean for your dishes, as well as help keep your spray arms unblocked.
Maintenance cleaning of your dishwasher can really help prevent any hardening of the dirt in the spray arm, as well as the rest of the machine. There are many machine cleaners available that we recommend to use at least once a month by running a maintenance clean with no dishes in the machine.
To find spare parts compatible with your specific dishwasher, you will need the model (type) number. This is usually made up of a combination of numbers and letters and can be found on the type plate which can be located on the inside of the dishwasher door, or all the way at the bottom (under the door, almost on the floor). In our shop, if you search by this number, you will be shown all the parts we have available that are suitable for your machine. Read here if you need help locating your type number.
