Common Dishwasher Problems and How to Fix Them
December 7, 2025
A dishwasher is meant to save time and effort, but when it malfunctions, even simple kitchen tasks become frustrating. Many dishwasher issues are minor and can be resolved with basic troubleshooting. Below are some common dishwasher problems homeowners face and practical steps you can take before calling a repair technician.
Dishwasher Will Not Power On
Possible reasons:
Power interruption or tripped breaker
Door not properly latched
Defective control panel
What you can try:
Start by checking your electrical breaker and reset it if necessary. Ensure the dishwasher door is fully closed and the latch is clean and secure. If the unit remains unresponsive, the control board or internal wiring may need professional attention.
Dishes Are Still Dirty After a Cycle
Possible reasons:
Spray arms blocked by debris
Clogged dishwasher filter
Water not hot enough
What you can try:
Remove the spray arms and rinse them thoroughly. Clean the filter located at the bottom of the unit. Running hot water at the sink before starting the dishwasher can also improve cleaning performance.
Dishwasher Is Not Draining Water
Possible reasons:
Clogged drain hose
Blocked pump
Garbage disposal connection issue
What you can try:
Check the drain hose for bends or blockages. Remove food particles from the pump area under the filter. If the unit was recently installed, confirm that the garbage disposal plug was properly removed.
Water Leaking from the Dishwasher
Possible reasons:
Worn or damaged door seal
Excess detergent use
Faulty inlet valve
What you can try:
Inspect and clean the door gasket regularly. Always use dishwasher-approved detergent in recommended amounts. Persistent leaks often mean the inlet valve needs professional repair.
Dishwasher Making Unusual or Loud Noises
Possible reasons:
Dishes obstructing spray arms
Worn motor or pump
Internal bearing damage
What you can try:
Rearrange dishes to ensure free movement of spray arms. If noise continues during every cycle, it’s best to have a technician inspect the appliance.
