Why Your Spray Arms are not Working

Are you wondering why your dishwasher spray arms are not working? Are you looking to secure repair services for your dishwasher? This dishwasher repair guide can help you. 

It’s no surprise that spray arms come up frequently in dishwasher repair conversations. After all, the dishwashing process significantly depends on the spray arms. So, when the spray arms aren’t rotating freely, it affects the dishwasher’s overall function.

You’re probably already wondering what causes the spray arms to become defective. The truth is several factors can affect the spray arms of your dishwasher and you’ll discover them soon. 

Here are a couple of reasons that cause your dishwasher to need repair for its spray arms. 

Faulty or blocked pumps

The spray arms of the appliance depend entirely on the water for its rotation. This water comes from the pump, and when the pump malfunctions, it may affect the spray arms. 

Likewise, when wastes and debris block the pump, the spray arms can’t work efficiently. This is because the pump cannot produce enough water pressure to rotate the spray arms. The resultant effect is the slow movement of your spray arms. 

Before you take your dishwasher for repair, you should check both the spray arms and the pump.

Water hoses

In most dishwashers, you may not be able to see the water tubes and connections. However, the water pumps use hoses to get water from the water source. 

When any of these hoses touch the spray arms, it can obstruct or disturb its movement. Likewise, if there are any issues within these hoses, the spray arms suffer. 

So, Before you ask why your spray arms are not working, check these connections. However, except you’re very skilled with a spanner, performing such checks may be somewhat tasking. In light of this, your best option may be to employ dishwasher repair services.

Spray Tower

You may be wondering what a spray tower means. The answer is simple. The spray tower is an additional compartment on the spray arms of some dishwashers for extra cleanliness. 

When the spray arm rotates, the spray tower provides an extra wash for the dishes.

However, food debris may sometimes clog up this spray tower. When this happens, it can affect the free movement of the spray arms. So, this is another possible reason your dishwasher sprayer arms are not spinning.
