Dishwasher problems and when you need to repair it

Dishwashers are one of the hardest working appliances in the kitchen, so when they develop a problem, you notice it right away.  Having a dishwasher makes life easier and reduces the amount of time you spend doing dishes in your kitchen. Nothing is exciting about washing the dishes, and if you live with your family, someone is probably struggling to wash all the dishes. Usually, a dishwasher lasts anywhere from seven to ten years. Unfortunately, some of them break down earlier than that.

Many people prefer to do their repairs since getting a repair or replacement can be very expensive. Below are some of the common problem areas that we’ve tried to address.

Most common dishwasher problems and solutions

A high-quality dishwasher is one of the most useful appliances in your house, offering the necessary cleaning power to keep plates, glasses, cutlery, and more ready for recurrent use. The modern kitchen needs the dishwasher to run at top efficiency at all times, but various frequent dishwashing issues might obstruct its function.

Like any other home appliance, your dishwasher may require repairs and maintenance. To assist you in identifying when problems occur, listed below are the most common dishwasher repair issues. These difficulties range from minor to major, but they will almost certainly require professional dishwasher repair services regardless of their degree.

Dishes don’t come out clean

One of the most frequently voiced complaints about dishwashers is that they do not efficiently clean dishes. If your dishwasher becomes ineffective unexpectedly, you may need to make some repairs. 

Solution – First, run a wash cycle using a dishwasher cleanser without any dishes in the appliance. This will remove any filth or grease from the machine. Additionally, you should inspect the strain screen, sprayer arms, and door gasket of the appliance and remove any oil or food waste contained within it. If the problem persists, you may have low pressure from the spray arms or a problem with another component that is inhibiting the dishwasher’s performance.

Dishwasher is unable to start

As with any other home appliance, the dishwasher must be powered by a dependable power source. If your dishwasher does not start, it may be improperly plugged in, or its wiring may be broken. Another frequent cause is a malfunctioning door latch or latch switch. The dishwasher will not start until the door is properly closed, and door problems will prevent wash cycles from starting. 

Solution – Check all power sources carefully. If there are no difficulties with your power source or dishwasher door, the unit’s electrical controls may malfunction. Contact a professional repair service company to fix the issue.

Dishwasher is not filling or is filling incessantly

A dishwasher requires a constant supply of water to run at maximum efficiency, yet it is not uncommon to see dishwashers that do not fill with water or that will not stop filling with water. The most typical source of water flow troubles in a dishwasher is a faulty water inlet valve. If the intake valve is defective, water may not be drawn into the appliance when needed. Alternatively, a stuck-open water inlet valve will continue to load your dishwasher long after the proper amount of water has been added. 

Solution – Problems with dishwasher float switches can lead to insufficient or excessive water levels in the dishwasher. When debris or waste is inside the appliance, these components can malfunction, indicating that the appliance is not holding enough water. Check the external waste or debris to fix the issue. 

Leaks in the dishwasher

Leaks from dishwashers can cause significant damage to your kitchen, necessitating rapid repair. The dishwasher’s heating element might be damaged or cracked, causing drainage hoses or gaskets leaks. 

Solution – Pump and seal problems can also cause dishwasher leaks. These components should be replaced as soon as possible if they appear faulty.

Dishwasher is not draining

A dishwasher that refuses to drain can eventually become a flooded dishwasher, causing havoc on your kitchen space. 

Solution – This issue is frequently caused by a malfunctioning check valve in the dishwasher’s drain pump. If the valve is faulty, it should be replaced. Additionally, you may require a new motor or drain sump. Ensure that you hire skilled dishwasher repair services for the finest outcomes.

Dishes are not properly dried

When the dishwasher cycle is finished, your dishes should be completely dry and ready for storing. If your dishes are noticeably moist following a wash cycle, you may have a problem with the appliance’s heating element. 

Solution – The only way to determine whether the heating element is functioning properly is to do a multi-meter test, which is a task best left to experienced dishwasher maintenance specialists.

Even though these common problems can be resolved by yourself, we recommend that you contact a professional repair service to address the issue effectively.

How to diagnose dishwasher problems?

In contrast to some of your other household equipment, your dishwasher will display particular signs when something is wrong. By recognising dishwasher problems early on, you can save money by reducing repair times. You may even be able to resolve minor issues on your own. Read the guidelines below to learn how to detect dishwasher problems independently.

A leaking dishwasher might signal several different issues.

  • Overloading 

By placing an excessive number of dishes in each load, you risk causing the machine to leak. Reduce the number of dishes and check to see whether the leak remains.

  • Defective Door Seal 

Inspect the plastic seal surrounding the dishwasher’s door. If the machine has cracks or holes, it may leak. Replacing the seal is a simple and inexpensive remedy.

  • Use of an excessive amount of Detergent 

Verify the detergent tray. If any soap residue remains, you’re using too much soap per load, which will cause your machine to leak.

  • Defective pipe connections 

Conduct a visual inspection of the pipes in the back of your machine. You may be able to stop your dishwasher from leaking by tightening any loose pipes.

If your dishes are dry and still dirty after being washed in the dishwasher, this indicates that your dishwasher is not filling with soap and water. This can occur as a result of one of the following:

The hot water valve is not in the open position. Under your sink, check to ensure that the hot water valve is fully opened. Opening the valve will allow water to enter your dishwasher if it is not.

  • There is a clog in the inlet valve. If the valve is clogged with debris and residue, cleaning it will restore functionality to the machine and allow it to fill.

It is normal for your dishwasher to have a small amount of water in the bottom. However, if you believe in excessive water, you may have a drain hose issue. Consult your machine’s handbook to determine the location of your dishwasher’s drain hose. Examine the drain hose for holes, breakage, and debris or soap residue.

How much does it cost to repair a dishwasher?

When your dishwasher fails to function properly, you may be tempted to repair it yourself. The do-it-yourself approach may appear to be a good idea. However, it is simpler to exacerbate the situation. When it comes to today’s high-tech dishwasher models, the most cost-effective alternative is to engage a professional equipped to manage any problems. Each professional’s quote covers labour as well as replacement parts. The average appliance handyperson charges between AU$ 80 and AU$ 330 for one hour of labour plus material costs. Dishwasher experts are not uncommon to charge an additional 20% above the wholesale price range for spare parts and materials. Naturally, quotes will vary according to the amount of damage.

How long do dishwashers last?

Before investing in a service, it’s critical to examine how long you’ve owned the dishwasher. We ask thousands of Australian families how long they held their appliances before replacing them in customer surveys. Based on these statistics, the average life expectancy of modern dishwashers was nine years. It would be prudent to conduct a study and determine whether the repair is worthwhile. When you analyse the prices, you may discover that repairing the dishwasher is more expensive than purchasing a new one. To help extend the life of your dishwasher, perform routine maintenance and use the recommended amount of dishwashing detergent.

Is it cheaper to repair a dishwasher or buy a new one? Is it worth fixing it?

Having a dishwasher alleviates the strain of washing pans and glassware. However, your sink can quickly become clogged with dishes when your dishwasher fails. Your initial thought may be to see if you can repair it yourself. Should you have it fixed by a professional? Or, in the worst-case scenario, will you require an entirely new machine?

When considering whether to replace or repair a dishwasher, there are two critical aspects: the availability of replacement parts and the appliance’s age.

  • Cost of a New Dishwasher

Dishwasher prices vary significantly depending on the brand and feature desired. A simple model costs around $400, while higher-end models cost well over $1,000. Consider installation fees; in a property with pre-existing hookups, the installation will cost between $50 and $100.

  • Cost to Repair a Dishwasher

Certain items can be repaired for free or for the cost of the parts. This will vary according to the nature of the issue and the dishwasher model you own. You’ll cost around $200 to engage a repair firm to address a typical dishwashing problem.

If the cost of repairs exceeds 50% of the cost of a new unit, you should replace it. Therefore, if the cost of replacing your current dishwasher is $500, you should not pay more than $250 to repair it.

Another indication that it’s time to replace your dishwasher is if you’ve had to make repeated repairs in the last year. While an occasional repair may be justified, when many components fail, it shows that the appliance as a whole is malfunctioning. Inspecting gaskets, seals, drains, and other readily accessible locations may assist you in determining if other components are nearing failure.
