Dishwasher Troubleshooting Guide – Problems and Solutions

A dishwasher is a worthwhile investment for those with a busy schedule. The best dishwasher in India does not only help you save time but also reduces the effort to get the dishwashing job done.

At times you may come by a problem in your dishwasher. If it isn’t a major issue you might be able to find a quick fix for it. Here are some of the common problems that we found in dishwashers along with simple troubleshooting solutions.

Troubleshooting Dishwasher Problems and their Solutions

Problem 1: Dishwasher is unable to clean the utensils properly


It might be caused by internal dirt present in the appliance. Also, a blockage in the inlet may restrict water from getting into the dishwasher. It may also depend on the detergent that is being used. Many times it is caused by hard water.


The first thing to do is to clean the insides of the appliance. Clean out any food debris that might exist in the filter as well as on the walls. Next, check for any blockages in the inlet pipe. Also, check if the sprayers can force out water consistently.

Another thing to check is the pressure of water, low pressure may result in less efficient cleaning. If you have been using a low-quality detergent, change it for the one specified by the brand. In case you think that hard water is causing the problem, think about getting a water softening procedure.

Problem 2: A noisy dishwasher


The noise can be caused by a dishwasher that hasn’t been cleaned for long. In more grave cases it might be caused because of a broken pump or defective spray arms.


Most dishwashers do make a noise, so make sure that it is an abnormal sound. Next, make sure to clean your dishwasher. If the noise persists, then it is better to call a technician who can help to replace the broken parts with original products.

Problem 3: The dishwasher smells off


The most common reason for a dishwasher being smelly is because it is unclean. It is generally because food debris or grease is trapped inside the appliance.


Try the mixture of vinegar and baking soda to clean your dishwasher. The first step should be to scrub the walls and corners of the dishwasher. Then, sprinkle baking soda on the top and bottom rack.

Also, add some vinegar to the appliance. Lastly, you need to run a heavy load cycle to make the dishwasher clean and smell good. To avoid this problem, always clean out food debris from the plates and run a pre-rinse before a full cycle. Cleaning the dishwasher properly will eliminate most of the problems arising time-to-time. It is the key to the prolonged life of your machine.

Problem 4: The dishwasher isn’t starting


There might be several reasons for which a dishwasher may fail to start. The most common problem is generally in the power source. But other problems include overloading and improper door handling.


The first thing that you try is to unplug and replug the dishwasher to see if it works. If not, then check if the power source is working or not. The next thing you can do is to check if you have overloaded the racks. Dishwashers generally beep or give a sign when it has been overloaded.

Another thing to check is the door. Make sure that the latching has been done properly. If there is too much wear and tear in the gasket, the dishwasher may stop running. Call a professional to replace the broken parts.

Problem 5: White spots on the utensils


White spots on the utensils can be caused by improper use of detergent, presence of hard water, or improper drying.


Firstly, you can try to run an extra drying cycle to see if it solves the problem. Start using the detergent according to brand instructions for best results from wash cycles. Also, an extra rinse cycle may help to get rid of the spots. If it is hard water, then you may need to utilize a water treatment procedure at your house.

Problem 6: A leaky dishwasher


Leaking may happen if the gasket is unable to hold in water. But, at times it may be because of the float switch’s improper position.


Thoroughly observe the door gasket to see if there is any wear or tear. You might also want to clean the gasket to remove any debris or grease that may have accumulated on it. Then, move on to check the float switch. The dishwasher may overflow or leak if the switch is in a downward position. Giving it proper cleaning and repositioning will often stop any further leakage.

Problem 7: Dishwasher isn’t dispensing soap or it is doing it improperly


It is usually caused when the water is unable to reach the compartment to properly dissolve the powder or pod.


Check to confirm that you are following the detergent guidelines properly. Next, make sure that there isn’t a blockage in the dispensing compartment or if it’s broken. Put some water to see that it’s flowing properly onto the racks. At times the problem might be caused by a utensil blocking the opening, so stack them well before each cycle.

Problem 8: Cleaning cycles are too long


The old age of the dishwasher, or a problem in the thermostat, or selection of the wrong program.


A dishwasher may take a long to clean a batch if the right temperature cannot be attained. So, have a look at the thermostat and heating element of your dishwasher. Brand new appliances do take a while to settle in and for the sensors to run properly. But, the cycle may also get lengthy once a machine turns old. Make sure that you are selecting the right program. Call a professional if the problem persists.


These are some of the common problems that might arise in your dishwasher. Though a DIY is often the easy way out, always consult a professional when an appliance is one warranty. Moreover, it is better to troubleshoot the dishwasher problems to maintain the health of your device.

In case of problems where repairing or replacement might be needed, it is best to call a professional. Do not shy away from contacting the customer care of a brand as they always have nice offers for their customers.
