How to Repair a Dishwasher
The days of washing dishes by hand are over for most homeowners thanks to a dishwasher in their home. A dishwasher is a very convenient kitchen appliance that saves a lot of time each and every day.
“The problem is that the average dishwasher only lasts around 10 years,” according to Robert Wyatt, appliance repair in Reno. This means that dishwashers are not the most durable type of appliance and will need routine maintenance and repair.
You can learn how to complete common dishwasher repair projects on your own with tips from our list below. We include several tips and troubleshooting guides to help identify the problem and solution. In the event you are not comfortable completing a repair, we recommend hiring a local appliance repairman in your area. OBX recommends some below.
Loud or unexpected noises coming from a dishwasher often indicates a problem. You must first determine the type of noise – is it grinding or thumping? Then you can determine the source of the noise. You will want to inspect the pump housing, motor brushings and washer arm bearing. In most cases, one of these dishwasher parts are the cause of the loud noise.
A leaking dishwasher is a serious problem considering the amount of water the appliance needs to use during an average washing cycle. This type of dishwasher repair often requires assistance from a trained appliance repair service in town. To attempt the repair on your own, first inspect the door seals, pump and water inlet valve for any noticeable malfunctions.

WON’T TURN ON
The most obvious reason a dishwasher won’t turn on is if it is unplugged. You must first be sure the appliance is plugged in and that all of the circuit breakers are correct too before continuing on with your diagnosis. The next parts of the dishwasher to inspect are its door latch switches, timers, electronic controls, motor relays and thermal fuses. You might find it difficult to identify the cause of this issue being that there are several parts to troubleshoot.
DOOR LATCH MALFUNCTION
A dishwasher door must be 100% closed and sealed before the appliance will begin functioning. Problems with a door latch or door that won’t close can be from a malfunctioning door latch kit. This is a serious problem but an easy repair that most DIY handymen are able to complete on their own.
A dishwasher must first fill in order to wash the dishes. Then all of the water must drain from the appliance before the heated drying cycle begins. If a dishwasher won’t fill, there is likely an issue with the water inlet valve, float switch or door switch. If a dishwasher won’t drain, you should inspect the drain pump motor, drain hose and timer.
WON’T RELEASE DETERGENT
The dishwasher in your kitchen should release detergent throughout the machine during the washing cycle in order to deep clean the dirty dishes. If there is no detergent then the dishes will not be washed after the cycle. “The bi-metal release, timer and wax motor are often the reason that detergent will not dispense from a dishwasher,” according to Dean Hutchinson, Lead Technician for appliance repair in Avondale.
DISHES AREN’T DRYING
In order for a dishwasher to function correct, it must both clean and dry dishes. If dishes are not dry after a wash cycle, there is likely a problem with the heating element on the appliance. You can also check the high limit thermostats and rinsing dispensers for issues as both parts can also lead a dishwasher not drying.
The dishwasher problems above are common on models 10 years and older. You can complete most of these repairs in an hour or less.
