Dishwasher Maintenance


The dishwasher is one very useful home appliance. It isn’t just easier and simpler than washing dishes and utensils by hand, it  also uses much less water. Despite its importance, most people don’t think about maintaining it. After all, the dishwasher gets cleaned every time the dishes do, right?  Unfortunately, this isn’t the case. The reality is that deposits and debris accumulate over time, and some of them interfere with its performance and functioning. Regular maintenance is necessary to keep your dishwasher running optimally. Below we’ll discuss how to clean  your dishwasher inside and out.

Interior Cleaning

Running your dishwasher helps clean it somewhat, so you don’t need to clean the inside particularly often if you use it regularly. All you have to do is use a deodorizer to keep it smelling nice. If you don’t use your dishwasher often, however, it may begin to smell. If this happens, simply run a cycle with regular detergent.

Exterior Cleaning

Use a wet sponge and dish detergent to wipe the exterior part of your dishwasher clean, then use soap and water to cleanse the rubber seal that lines it. Steam heats up the rubber during the washing and drying process, so this is an area that is susceptible to dust and fungus. Washing the seal will help remove and prevent dust or fungus particles from accumulating over time.

Filter Cleaning

The filter, which must be cleaned regularly, is located at the bottom of the dishwasher or below the lower spray arm. Read your owner’s manual to learn how to remove and clean your dishwasher’s filter. If the filter is broken or contains holes, you may need to replace it in order to protect the pump. Replacing a broken filter also protects the motor seals from excess particles in the dishwasher.

Rust Removal

Rust stains can be eradicated with rust remover, which can be found in a hardware or grocery store. Of course, it’s best to address the rust problem at its source. If the problem is rusty pipes, for instance, you can use water softeners to remove excess iron from the water.

Spray Arm Cleaning

The water jets, which are located on the spray arms of the dishwasher, can get clogged over time. Tiny food particles or even mineral deposits may obstruct the water flow. This can be prevented with regular cleaning, however, which will also greatly improve the efficiency of your dishwasher.

Hiring a Professional Plumber

Aside from the fact that dishwashers are expensive, delicate machines, there are  several other reasons you should hire a licensed plumber to perform dishwasher maintenance:

1. An improperly maintained dishwasher won’t work properly. It will leak, waste water, and, at worst, cause water damage to surrounding areas.

2. Any water or electrical damage caused by improper maintenance can and will cause you a lot of problems later on. It may even nullify any homeowner’s insurance you may have, as insurers can easily refuse to pay for the damages by arguing that they were caused by negligence on your part.

3. Professional plumbers will ensure the maintenance tasks are performed as efficiently as possible and will clean up properly after they’re finished, leaving you with a kitchen that looks great and is free of accidental damage.

4. A professional plumber doesn’t just get the work done right, they can also fix it for free if anything goes wrong, This is one of many benefits you won’t get if you try to do everything yourself.


It’s not impossible to apply these do-it-yourself tips to perform dishwasher maintenance yourself. It would be wise, however, to hire a professional plumber to perform any tasks that you don’t feel completely comfortable with. Remember that damages require repairs. Whether it’s repairing the dish rack or replacing the filter, hiring a professional plumber is your best option.
