Quick answer: A dishwasher that leaves dishes dirty almost always has a cleaning-system problem: clogged spray arms or a dirty filter, hard-water scale, poor loading, or water that is not hot enough. Winnipeg tap water is hard, so mineral buildup on the spray arms and heater is a common local cause. Start by pulling the filter and rinsing it, then clear the tiny holes in the spray arms with a toothpick. Run the hot tap at the sink before you start a cycle so the dishwasher fills with hot water. If dishes are still dirty after that, the wash pump or heating element may be failing.
Why your dishwasher isn’t cleaning
Poor cleaning traces to water flow, water temperature, or how the machine is loaded. Here is what each cause points to. If dishes come out clean but spotty or filmy instead, that is a different issue, covered in our guide on a dishwasher leaving film and spots. For other faults, our step-by-step troubleshooting guide covers the full checklist.
| Cause | Fix |
|---|---|
| Clogged filter and spray arms | Rinse the filter, clear the spray-arm holes |
| Hard-water scale (common in Winnipeg) | Run a citric-acid or vinegar cleaning cycle |
| Overloading or blocked spray arms | Load so arms spin freely, do not nest items |
| Water not hot enough | Run the hot tap first, set the heater option |
| Worn wash pump or chopper | Weak spray pressure, needs a technician |
Clean the filter and spray arms first
This one step fixes most poor-cleaning complaints. Twist out the filter at the bottom of the tub and rinse it under the tap, then wipe the sump. Lift off the spray arms and clear each jet hole with a toothpick, since trapped grit blocks the water and leaves food on your dishes. Do this monthly and cleaning improves on its own.
Winnipeg hard water and scale
Winnipeg has hard tap water, and the minerals leave a chalky scale on the spray arms, filter, and heating element over time. That scale narrows the jets and dulls the heat, so dishes come out gritty. Run an empty hot cycle with a cup of white vinegar or a citric-acid cleaner once a month to strip the buildup and restore the spray.
Loading and detergent
How you load matters as much as the machine. Overpacking blocks the spray arms and shadows dishes from the water. Leave space, angle bowls down, and keep tall items from stopping the arms spinning. Use fresh dishwasher detergent, since powder and tablets lose strength if they sit in a damp cupboard for months.
Water temperature
Dishwashers need water around 50 degrees Celsius to dissolve detergent and cut grease. If your hot water travels a long way to the kitchen, the first fill can be cool. Run the hot tap at the sink until it is hot, then start the cycle. Turning on the heated-wash or sanitize option helps in winter when incoming water is colder.

Frequently Asked Questions
Why is my dishwasher not cleaning dishes properly?
The usual causes are a clogged filter or spray arms, hard-water scale, overloading, or water that is not hot enough. Rinse the filter, clear the spray-arm holes, and run the hot tap before starting. If dishes are still dirty, the wash pump may be weak.
How do I clean my dishwasher filter?
Twist out the filter at the bottom of the tub, rinse it under the tap, and wipe the sump around it. Do this monthly. A clogged filter is the most common reason a dishwasher stops cleaning well.
Does hard water affect my dishwasher in Winnipeg?
Yes. Winnipeg has hard water, and the minerals scale up the spray arms, filter, and heater, which weakens cleaning. A monthly hot cycle with vinegar or a citric-acid cleaner strips the buildup and restores spray pressure.
