How to Replace Dishwasher Propeller Sprayer ? The sprayer arms in your dishwasher are how it works its magic. Without the sprayer arms, jetting water wouldn’t hit your dishes and they would not effectively be cleaned. So if you’re noticing that your dishes have stopped coming out clean, a good place to start looking is the sprayer arms. You may determine that one or both are no longer functioning properly and may need to be cleaned, repaired, or replaced.
Dishwasher Propeller Replacement
Water is forced through the spray arms of a dishwasher by the unit’s pump and motor assembly. The force of the water propels the spray arms, spraying water and detergent onto the dishes on the dishrack. Depending on your model, you may have only one spray arm located on the bottom of the dishwasher, or you may also have an upper spray arm located at the top of the unit above the upper dishrack. There may or may not also be a plastic tower extending from the center of the lower spray arm, whose purpose is to spray an additional blast of water at the dishes.
Remove the lower dishrack from the unit. If your dishwasher has a spray tower in the center of the spray arm, remove it now by unscrewing it with your hand. You should see a bolt in the center of the spray arm. Remove the bolt and then remove the lower spray arm by pulling up on it. If your particular spray arm is not held in place with a bolt, lift up on the spray arm to remove it from the unit. You may need to rock it back and forth a little to help ease the process.
If there are any washers used with your spray arm, make sure you return them in the same order they came off. If you are replacing the spray arm, simply discard the spray arm you have just removed, and insert a new one in its place. To clean your spray arm, soak it in warm, soapy water. Rinse it clean with a high pressure spray of water. Return spray arm to dishwasher.
Safety First! Please make sure that you have switched your appliance off at the mains before starting your repair.
Replace The Lower Spray Arm
We need to be able to get to the spray arms of course! To gain access, carefully slide out the baskets. If you’re replacing the lower sprayer, it simply pops out and you can replace it with your new one by clicking it into place – it really is that easy!
Replace The Upper Spray Arm
The upper spray arm and pipe is fixed to the bottom of the upper basket, which can be removed by applying some gentle pressure. The new one should simply slot straight in.
Replace The Spray Arm Supply Channel
Take a little look inside the cavity of your dishwasher now…you should see a long plastic tube, which is known as the supply channel. This delivers water from the bottom of the appliance, directing it from the wash motor to the upper spray arm.
For the model in this video, the design has changed over the years. It might not be so obvious, but there is a slight size difference so you may have to replace this too. To change the upper spray arm channel connector, simply prise out the metal securing clips with a flat-head screwdriver.
Remove The Spray Arm Channel Connector
Once the supply channel is away from the dishwasher cavity, use a flat-head screwdriver to remove the old spray arm channel connector.
Pay attention to get the connector aligned properly before clicking the channel into position.
Fit The Baskets
Nearly there now all you need to do is put the baskets back in your dishwasher, as they were located before, and there you have it – your dishwasher now has new spray arms thanks to your hard work!
Congratulations – you have now successfully been able to replace your dishwasher spray arms! You can now get back to being able to have the dishwasher do all the hard work, rather than you have to clean them by hand!
