Dishwasher spray arm clogged

Dishwasher spray arm clogged. The dishwasher is one of the most helpful inventions to come along in the last century.

You can load it up with dirty dishes, set it, and forget it. Instead of scrubbing each dish by hand and then spending time drying them, the dishwasher does all the hard work for you.

All you have to do is unload it when it’s done. The spinning water-sprayer arms are what make the dishwasher so effective.

They make sure that each dish is hit with hot, soapy water from nearly every angle. This simulates the agitation of hand-scrubbing and gets your dishes clean in no time.

We will discuss here how we can repair the sprayer arms of dishwasher.

Vinegar-rinse Sprayer Arms

Over time, the holes in your dishwasher’s sprayer arms can become clogged with a chalky buildup of minerals.

This is caused by hard water, which is simply water that contains a high concentration of minerals like calcium and magnesium.

Hard water can be a nuisance, preventing soap from sudsing and leaving a chalky residue on sinks, tubs, skin, and laundry.

It can also clog pipes, faucets, and nozzles. However, the mineral buildup can be easily removed with white vinegar. Simply pour vinegar over the clogged sprayer arms to dissolve the scale.

Clear the Sprayer Arm Holes with a Poke

If your dishwasher’s sprayer arm holes are starting to get clogged with built-up scale, there’s an easy way to clear them out.

Just use the straightened end of a paper clip. Insert the end of the paper clip into each clogged hole and push.

This will clear away the small hardened scale-cap and allow water to flow again. Keep in mind that this is only a temporary fix, as there will still be build-up inside the arm water line.

Another possible issue that may occur is with the spinning sprayer arm. This requires a bit more of a repair as it involves the motor, but you can start by making sure the track is clear.

Take the sprayer arm off the socket and take a close look at where the two pieces meet. You can also use vinegar to clean any scale that may have built up there.

Lastly, ensure that there is no food buildup or grime in the area as this can be a common issue.


Is it possible to disassemble the dishwasher spray arm?

If you’re not confident in your ability to take apart the spray arms, you can always hire a professional. However, most homeowners should be able to handle the job.

If the spray arm is stuck and you can’t remove it, you can buy new arms from the manufacturer to replace the clogged ones.

What causes a dishwasher not to spray water?

There are several potential reasons why your dishwasher might not be spraying water, each having to do with different parts of the dishwashing process.

In many cases, the circulation pump, spray arms, chopper blades, or water inlet valve are to blame.

If you’re noticing a lack of water pressure, it’s likely that one (or more) of your components is clogged or has failed entirely.


Taking care of the dishes is definitely a chore, but it doesn’t have to be so hard. The best dishwashers make it a lot easier to get this task done, with features that make cleaning more efficient. A dishwasher with a powerful motor and spinning water-sprayer arms can make a big difference in the cleanliness of your dishes. If your dishwasher doesn’t seem to get things nearly as clean as it should, it might be time to consider replacing it.
