How to Repair a Dishwasher

A dishwasher is a must-own appliance for most homeowners. You can save yourself several hours each week by installing a dishwasher in your kitchen. The downside is that a dishwasher is not the most durable type of kitchen appliance. A good brand and model will only last 10 years before issues start to arise. You can repair some of these issues on your own. Others will need the attention of a professional appliance repair company.

APEX has created a list of some of the most common dishwasher issues and how to repair them. Several of the repairs require no more than 30-60 minutes to complete. Others are more serious and will require scheduling service from an appliance repairman near your home. Please contact us with questions.


Below are troubleshooting tips from APEX for some of the main problems you will find on a broken dishwasher:


A common symptom for any broken appliance is for loud noises to come from the machine. This is true of dishwashers too. There are different loud noises and each signifies a different issue. “You will need to determine if the noise is a rattle coming from the pump housing or more of a grinding sound from a worn-down washer arm bearing. Then you will need to replace the malfunctioning part during the repair,” according to Jeff Stevens, Lead Technician Victory Indio Appliance Repair.



A dishwasher requires several gallons of water to operate each cycle. A leak could lead to gallons of water on the floor of your kitchen and home and requires immediate attention. In the event of a leaking dishwasher, we recommend hiring an appliance repair service able to provide same-day attention. Otherwise, DIY repairs should start by looking for worn pump and door seals or a failed water inlet valve.


The most obvious reason a dishwasher won’t turn on or start is if it is not plugged in. The other reason is if a circuit breaker isn’t switched on. If neither of these issues are the problem you will need to investigate further and check to see if the timers, door latch switches, motor relays, thermal fuses and electronic controls are all working as expected. This can lead to a major repair where professional assistance is required.


The first step in a dishwasher cycle is for the unit to fill with water. If this doesn’t occur, then there is a problem that needs attention. You should inspect the float switch, door switch and the water inlet valve. The second step is for the unit to drain all of the water before the drying function begins. In the event the water doesn’t drain, test the dishwasher drain hose, pump and timer.


As a dishwasher fills with water, it should also dispense detergent throughout the appliance in order to clean the dirty dishes inside. The dishes won’t be clean if there is no detergent released. This issue is the result of a broken wax motor, timer or bi-metal release. Also be sure the detergent capsule is full before turning on the appliance to wash dishes.

All homeowners have different comfort levels when it comes to performing repair projects. Your comfort level and experience will determine your ability to complete the repairs above on your own or whether it would be best to rely on the help of a professional handyman or appliance repair company near your home.
