The Top 4 Reasons Your Dishwasher Is Not Cleaning Dishes
1. Clogged or Dirty Spray Arms
Your dishwasher cleans dishes by spraying hot water through rotating spray arms. If the holes in those arms are clogged with mineral deposits, food particles, or hard water buildup, water pressure drops dramatically — and your dishes won’t get clean.
Signs of this problem:
- Dishes on the top rack come out dirtier than the bottom rack (or vice versa)
- You can see visible gunk or scale on the spray arm holes
- Water is leaving residue even after a full wash cycle
Quick fix: Remove the spray arms (they usually snap or unscrew off), soak them in white vinegar for 20–30 minutes, and use a toothpick or thin wire to clear blocked holes. Rinse thoroughly and reinstall.
2. Leaving Water in the Bottom (Drainage Problems)
A dishwasher that’s leaving water in the bottom at the end of a cycle has a drainage issue. Standing water at the bottom of your dishwasher not only means your cycle didn’t complete properly — it also creates a breeding ground for bacteria and mould, and can cause unpleasant odours.
Common causes include:
- Blocked or dirty filter at the bottom of the tub
- Kinked or clogged drain hose
- Faulty drain pump or pump motor
- Garbage disposal connection issues (if your dishwasher drains into a disposal)
Start with the filter — it’s the most overlooked maintenance item in most households. Remove it, rinse it under warm running water, and use a soft brush to scrub off any grease or debris. If the problem persists after cleaning the filter, the drain hose or pump may need professional attention.
3. Door Won’t Close Properly
This one surprises a lot of homeowners: if your dishwasher door won’t close properly, the wash cycle may still run — but it won’t clean effectively. A poor seal means water pressure escapes, the spray system underperforms, and heat is lost during the cycle.
A faulty door latch or worn door gasket can cause:
- Water leaking from the door during a cycle
- Dishes not cleaning because the spray system loses pressure
- Error codes or mid-cycle shutdowns on newer models
Inspect the door gasket (the rubber seal around the door frame) for cracks, hardening, or deformation. If it’s damaged, it needs to be replaced. Also check the latch mechanism — if it feels loose or doesn’t click firmly, it may need adjustment or replacement. This is a repair best handled by a local appliance technician, as incorrect installation can cause leaks.
4. Detergent Dispenser Not Opening or Wrong Detergent Use
If the detergent dispenser doesn’t open during the wash cycle, your dishes are essentially being rinsed with plain hot water. This is more common than people think and often goes unnoticed because the dishwasher still runs its full cycle without any error.
Other detergent-related causes of poor cleaning include:
- Using the wrong type of detergent (liquid hand soap can damage the machine)
- Overloading dishes that block the dispenser door from opening
- Old or clumped detergent pods that don’t dissolve properly
- Not using a rinse aid, leading to water leaving residue on glassware
Always use dishwasher-specific detergent, ensure dishes aren’t blocking the dispenser, and keep your detergent in a dry location. If the dispenser spring or latch is broken, a technician can replace it quickly.

How to Troubleshoot Your Dishwasher at Home
Before calling anyone, run through this quick troubleshooting checklist. Many Ottawa homeowners fix minor issues themselves with just a few minutes of effort.
- Check and clean the filter. Located at the bottom of the tub, it should be cleaned every 1–2 months.
- Inspect the spray arms. Remove them and clear any clogged holes. Spin them to make sure they rotate freely.
- Run a hot water tap before starting. Let your kitchen sink run hot before starting the cycle so the dishwasher fills with hot water from the start.
- Check the door seal and latch. Make sure the door clicks firmly shut and the gasket is intact.
- Verify your detergent dispenser is opening. Run a short cycle, then open mid-way to see if the dispenser has released.
- Run a cleaning cycle. Place a cup of white vinegar in the bottom rack and run a hot cycle. This removes buildup and odours.
If you’ve gone through all of these steps and your dishwasher is still not cleaning dishes properly, it’s time to call a professional dishwasher repair service.
When to Call a Professional Dishwasher Technician
Some dishwasher problems are straightforward enough to tackle yourself. Others require experience, tools, and replacement parts — and attempting them without proper knowledge can turn a simple fix into a costly repair or even water damage.
Call a local appliance technician if you notice:
- Standing water that won’t drain even after cleaning the filter
- The door won’t close properly and the gasket or latch appears damaged
- Unusual grinding, humming, or buzzing sounds during a cycle
- Water leaking from under the door or beneath the machine
- Error codes appearing on the control panel that don’t reset
- Dishes consistently not cleaning despite a clean filter and proper detergent use

Prevention & Maintenance Tips to Keep Your Dishwasher Running Smoothly
Regular maintenance is the single best way to avoid emergency repairs and extend the life of your dishwasher. These habits take only minutes but can add years of reliable performance.
Task | Frequency | Why It Matters |
Clean the filter | Every 1–2 months | Prevents drainage issues and odours |
Run a vinegar cleaning cycle | Monthly | Removes mineral buildup and bacteria |
Inspect the door gasket | Every 3–6 months | Catches wear before it causes leaks |
Check spray arm holes | Every 3 months | Ensures even water distribution |
Refill rinse aid | When indicator is low | Prevents water leaving residue on dishes |
Scrape dishes before loading | Every use | Reduces food debris clogging the filter |
Ottawa’s tap water has higher mineral content than many Canadian cities, which accelerates scale buildup on spray arms and heating elements. Running a monthly vinegar or commercial dishwasher cleaner cycle makes a noticeable difference in long-term performance.

Frequently Asked Questions About Dishwasher Repair in Ottawa
Q: Why is my dishwasher running but not cleaning dishes?
A: The most common causes are clogged spray arms, a dirty filter, a faulty detergent dispenser, or low water pressure. Start by cleaning the filter and spray arms. If the problem persists, a professional dishwasher repair service can diagnose the underlying issue quickly.
Q: Why is my dishwasher leaving water in the bottom after a cycle?
A: Standing water at the bottom usually points to a blocked filter, clogged drain hose, or a failing drain pump. Clean the filter first — it’s the most common culprit. If water is still pooling, call a local appliance technician to inspect the pump and hose.
Q: Can a dishwasher door that won’t close properly affect cleaning performance?
A: Yes. If the door won’t close properly, the spray system loses pressure and the tub can’t maintain the temperature needed for effective cleaning. A worn door gasket or broken latch will need replacement — a quick fix for an experienced technician.
Q: How much does dishwasher repair cost in Ottawa?
A: Repair costs vary depending on the issue and parts required, but most common dishwasher repairs in Ottawa range from $100 to $300. At Yanfix, we provide upfront pricing before any work begins so you can make an informed decision.
Q: Is it worth repairing a dishwasher or should I replace it?
A: As a general rule, if the repair cost is less than 50% of the replacement cost and the appliance is under 10 years old, repair is usually the smarter financial choice. A Yanfix technician can give you an honest assessment so you’re not spending money unnecessarily.
Q: How do I find a reliable dishwasher repair service near me in Ottawa?
A: Look for a local company with same-day availability, transparent pricing, and a service warranty. Yanfix ticks all three boxes — we serve all Ottawa neighbourhoods with a 15-minute response time and a 90-day repair warranty.

Conclusion
A dishwasher not cleaning dishes is inconvenient, but it’s rarely a sign that you need a full replacement. In most cases, the problem comes down to a clogged spray arm, drainage issue, poor door seal, or detergent problem — all of which are fixable.
Start with the basics: clean the filter, inspect the spray arms, and check your detergent. If those steps don’t resolve the issue, don’t wait for the problem to worsen. Water damage from an unresolved leak or a seized pump motor can turn a $150 repair into a $600 one.
