A dishwasher can save hours of work in a busy household, but when it stops cleaning properly, won’t drain, leaks water, or refuses to start, it can quickly become frustrating.
Some dishwasher problems are caused by simple issues such as a blocked filter, incorrect loading, or low water supply. Other problems may involve the drain pump, heating element, spray arms, door seal, or electronic controls.
If you’re looking for dishwasher repair Edmonton services, understanding the common problems can help you identify when basic troubleshooting is enough and when professional service may be needed.
1. Dishwasher Is Not Draining
One of the most common dishwasher problems is standing water left inside the tub after a cycle.
Possible causes include:
- Clogged filter
- Blocked drain hose
- Food debris
- Drain pump problems
- Garbage disposal connection issues
- Drainage blockage
Start by checking whether the dishwasher filter is visibly blocked. If your model has an accessible filter, clean it according to the manufacturer’s instructions.
If water continues to remain inside the dishwasher after basic cleaning, the drain system may require professional inspection.
If your washing machine is also experiencing problems, see our washing machine repair Edmonton service.
2. Dishwasher Is Not Cleaning Dishes Properly
If dishes are coming out with food particles, grease, or residue, several things could be affecting cleaning performance.
Common causes include:
- Clogged spray arms
- Dirty filter
- Incorrect loading
- Insufficient water
- Low water temperature
- Using the wrong detergent
- Spray-arm blockage
Make sure dishes aren’t blocking the spray arms and that the dishwasher isn’t overloaded.
Cleaning the filter and spray arms regularly can also help maintain proper water circulation.
3. Dishwasher Is Leaking Water
Water underneath your dishwasher should not be ignored.
Possible causes include:
- Damaged door gasket
- Loose hose connection
- Blocked drainage system
- Excessive detergent
- Door alignment problems
- Faulty internal component
First, check whether the dishwasher door is closing completely and whether the visible seal looks damaged.
If water continues to leak, stop using the appliance until the source can be identified.
Persistent leaks can potentially damage flooring, cabinets, and surrounding areas.
4. Dishwasher Is Not Starting
If your dishwasher doesn’t start when you press the button, check a few basic things first.
Make sure:
- The dishwasher has power
- The door is fully closed
- The correct cycle has been selected
- The control panel isn’t showing an error
- The circuit hasn’t tripped
Some dishwashers won’t begin a cycle if the door isn’t properly latched.
If the appliance has power and the door is closing correctly but the dishwasher still won’t start, the issue could involve the door latch, control panel, timer, or electronic control system.
5. Dishwasher Is Making Strange Noises
Some dishwasher sounds are normal. Water spraying against the dishes, the drain pump running, and occasional clicks during a cycle can all be part of normal operation.
However, new or unusually loud sounds may indicate a problem.
Watch for:
- Grinding
- Loud buzzing
- Repeated clicking
- Rattling
- Humming
- Vibrating
A small object or piece of broken dishware can sometimes become trapped in the dishwasher. If the unusual noise continues, professional diagnosis can help identify the source.
6. Dishwasher Is Not Drying Dishes
If your dishes are still very wet after a completed cycle, the drying system may not be working properly.
Possible causes include:
- Heating element problems
- Incorrect cycle selection
- Ventilation issues
- Rinse-aid issues
- Faulty thermostat
- Control-system problems
Some modern dishwashers use different drying technologies, so performance can vary between models.
If your dishwasher previously dried dishes normally and has suddenly stopped doing so, it may be worth having the appliance inspected.
7. Dishwasher Has a Bad Smell
A dishwasher can develop unpleasant odors when food particles, grease, or residue accumulate inside the appliance.
Start with basic maintenance:
- Clean the filter
- Wipe the door seal
- Remove visible food debris
- Clean the dishwasher interior according to the manufacturer’s instructions
- Check the drain area
If the smell continues despite cleaning, there may be trapped debris or a drainage problem that needs further inspection.
8. Dishwasher Leaves White or Cloudy Residue
White spots or cloudy marks on glasses and dishes can have several causes.
These may include:
- Hard water
- Too much detergent
- Incorrect detergent
- Poor rinsing
- Mineral deposits
- Rinse-aid issues
Edmonton-area homeowners may encounter mineral-related residue depending on their water conditions and household setup.
Adjusting detergent and rinse-aid use according to the manufacturer’s recommendations may help.
If the problem continues, inspect the spray system and water supply.
9. Dishwasher Is Not Filling With Water
A dishwasher needs an adequate water supply to complete its cleaning cycle.
If you hear the appliance running but little or no water enters the tub, possible causes include:
- Water supply problem
- Closed water valve
- Inlet valve issue
- Blocked inlet screen
- Float switch problem
- Control-system fault
Before arranging service, confirm that the household water supply is functioning and that the dishwasher’s water supply valve is open.
If the problem remains, professional diagnosis may be required.
10. Dishwasher Stops During the Cycle
A dishwasher that starts normally but stops before completing the cycle may have an underlying problem.
Potential causes include:
- Overheating
- Water supply issues
- Drainage problems
- Door latch problems
- Heating-system failure
- Control-board issues
- Error conditions
Write down any error code displayed by the dishwasher. The code can provide useful information to the technician when diagnosing the appliance.

- It won’t start

What Can You Check Before Calling for Dishwasher Repair?
Before scheduling a service appointment, there are several simple checks you can make.
Check the Filter
Remove food particles and debris according to your dishwasher manufacturer’s instructions.
Inspect the Spray Arms
Make sure the spray arms can rotate freely and aren’t blocked by dishes or debris.
Check the Door
Make sure the door closes completely and the latch engages properly.
Check the Water Supply
Confirm that the dishwasher’s water supply valve is open.
Check the Drain Area
Look for visible debris that could be preventing water from draining.
Check for Error Codes
If the display shows an error code, make a note of it before contacting a technician.
How to Maintain Your Dishwasher
Regular maintenance can help your dishwasher operate more effectively.
Clean the Filter Regularly
Food particles can accumulate in the filter and affect drainage and cleaning performance.
Don’t Overload the Dishwasher
Leave enough space between dishes so water can circulate properly.
Keep Spray Arms Clear
Check the spray holes for visible debris and clean them according to the manufacturer’s instructions.
Use the Recommended Detergent
Follow the dishwasher manufacturer’s recommendations for detergent quantity and type.
Inspect the Door Seal
A damaged or dirty gasket can contribute to leaks.
How Much Does Dishwasher Repair Cost in Edmonton?
The cost of dishwasher repair depends on several factors, including:
- Type of problem
- Dishwasher brand
- Appliance model
- Required replacement parts
- Labour
- Diagnostic/service fees
A simple blockage may require much less work than replacing a pump, heating element, valve, or electronic control component.
Before approving a major repair, ask about the estimated parts and labour costs.
Repair or Replace Your Dishwasher?
A dishwasher that develops one problem doesn’t necessarily need to be replaced.
Repair may make sense when:
- The dishwasher is relatively new
- The problem is isolated
- Replacement parts are available
- The appliance is otherwise in good condition
- The repair cost is reasonable
Replacement may be worth considering when:
- The dishwasher is older
- Multiple components are failing
- Repair costs are very high
- The appliance has frequent recurring problems
A professional diagnosis can help you understand the condition of the appliance before deciding.
Why Choose Professional Dishwasher Repair?
Dishwashers contain electrical, plumbing, heating, and mechanical components that work together.
Trying to replace a component without finding the actual cause of the problem can result in unnecessary expenses.
A professional technician can:
- Diagnose the problem
- Inspect relevant components
- Identify the likely cause
- Explain repair options
- Determine whether parts need replacement
- Help you decide whether repair is practical
For electrical, water-supply, heating, and internal component issues, professional service can be a safer option than attempting an unfamiliar repair.
