Quick Answer: Dirty dishes after a wash cycle are usually caused by clogged spray arms, a blocked filter, or water that is not hot enough. Check the filter first — it takes 2 minutes and is free. Call (437) 524-1053 if cleaning the filter does not help.

Why Is My Dishwasher Not Cleaning Dishes?

A dishwasher that runs a full cycle but leaves food residue, spots, or cloudy film on dishes has one or more of these problems: the water is not reaching the dishes with enough pressure, the water is not hot enough to activate the detergent, or the detergent is not dispensing correctly. Each of these has a specific cause that a technician can identify quickly.

What Are the Most Common Causes?

  • Clogged spray arm holes: The rotating spray arms have small holes that can become blocked with food particles, hard water scale, or broken glass fragments. Blocked holes reduce water pressure and leave dead spots in the wash pattern.
  • Dirty or clogged filter: Most modern dishwashers have a manual-clean filter at the bottom of the tub. If not cleaned monthly, it builds up grease and food debris that recirculates dirty water through the spray arms.
  • Water temperature too low: Dishwashers need water at 49–60°C to activate detergent and dissolve grease. If your hot water heater is set below 49°C, or if the dishwasher's heating element has failed, dishes will not come clean.
  • Failing wash pump: The pump that circulates water during the wash cycle loses pressure as the motor bearings wear. Low pump pressure means the spray arms do not spin fast enough to clean effectively.
  • Detergent dispenser not opening: If the dispenser door is stuck closed or the spring mechanism is broken, detergent never reaches the water during the wash cycle.
  • Hard water mineral buildup: Toronto's water leaves white scale deposits on dishes and inside the dishwasher. This is not a repair issue but is solved with rinse aid and monthly cleaning.

How to Check Before Calling a Technician

1

Clean the filter

Remove the bottom rack. Twist out the cylindrical filter at the tub floor (usually quarter-turn counterclockwise). Rinse under hot water and scrub with a soft brush. Replace and run a test cycle.

2

Check and clean the spray arms

Remove the upper and lower spray arms (usually just pull up or unscrew). Hold each over the sink and run water through them to check flow. Use a toothpick to clear any blocked holes.

3

Test water temperature

Run your kitchen hot water tap until fully hot, then check the temperature with a thermometer. If below 49°C, increase your water heater setting. Running the hot water tap before starting the dishwasher also helps.

4

Watch the detergent dispenser

Start a cycle and open the door during the main wash phase. Check whether the detergent dispenser lid has opened and detergent has released. If not, the dispenser mechanism needs repair.

5

Check loading habits

Overloading blocks spray arms from rotating. Nesting bowls or placing items upside-down prevents water from reaching them. Proper loading alone can dramatically improve cleaning results.

Note: If you find broken glass or ceramic fragments at the bottom of the dishwasher tub, remove them before running another cycle. Fragments circulate through the pump and spray arms, causing damage to both components that can turn a simple cleaning service call into a pump replacement.

Frequently Asked Questions

Why is my dishwasher leaving food on dishes?
The most common causes are clogged spray arm holes (food debris blocking water jets), a dirty or clogged filter at the bottom of the tub, low water temperature (should be 49–60°C at the dishwasher), or a failing wash pump that reduces water pressure.
Why are my dishes coming out with white spots or cloudy film?
White spots and film are caused by hard water mineral deposits. Toronto's water has moderate hardness. Use a rinse aid in every cycle, ensure your detergent dispenser is working, and run a monthly dishwasher cleaner cycle to remove mineral buildup.
How much does dishwasher repair cost in Toronto?
Most dishwasher repairs in Toronto run $130–$280 CAD including parts and labour. Spray arm replacement is $110–$170 CAD. Wash pump replacement is $180–$260 CAD. Inlet valve replacement is $140–$200 CAD. A filter clean and service call runs $90–$130 CAD.
Should I repair or replace a dishwasher that is not cleaning well?
If the dishwasher is under 8 years old, repair is almost always worth it. Simple issues like clogged spray arms and dirty filters are resolved for under $150 CAD. Major pump or control board failures on machines over 10 years old are worth comparing against the cost of a new unit.
