Most appliance breakdowns aren't mysterious. They're the slow, predictable result of months (or years) of small things — lint that was never cleared, a filter that was never rinsed, a door seal that was never wiped. The appliance didn't fail. It was slowly pushed toward failure. This guide tells you exactly what to check, how often, and what to do about it.
Here's something the repair industry isn't always eager to admit: a significant portion of service calls are not caused by defective parts. The motor didn't fail. The pump didn't break. The machine just got abused — gradually, innocently, by people with full schedules and no reason to suspect the dishwasher was silently suffering.
We're not judging. Life is busy. But if you can spare 10 minutes a month across your whole kitchen and laundry setup, you can extend the life of your appliances by years and skip a handful of repair bills entirely.
Below is a breakdown by appliance — what to check, how often, and why it actually matters.
How to read this guide
Each appliance has checks labeled Daily, Weekly, Monthly, or Annual. "Daily" doesn't mean you need to set a reminder — it just means building a habit around how you use the machine. The rest are worth putting in your calendar once.
🪖 Washing Machine
The washer is the appliance most likely to flood your home and least likely to get any maintenance attention. It sits in a corner, you throw clothes in, you forget about it. Here's what it actually needs:
DailyDon't leave wet laundry sitting in the drum after the cycle ends. It breeds mildew, and mildew smell is almost impossible to fully get rid of without a service call.
WeeklyAfter the last load of the week, leave the door open (front-loaders) or the lid up (top-loaders) to let the drum dry out. Moisture trapped inside is the #1 cause of that "musty" smell.
MonthlyRun a hot wash cycle with a washing machine cleaner tablet or a cup of white vinegar and no laundry. Clears detergent buildup, mineral deposits, and biofilm from the drum and pump.
MonthlyPull the detergent drawer out completely and rinse it under the tap. You'd be amazed what's in there. Clogged detergent drawers cause dispensing problems that look like a broken washer but aren't.
MonthlyCheck the supply hoses behind the machine for any bulging, cracking, or moisture. Washer hoses fail without warning and the results are catastrophic. If the hoses are rubber and more than 5 years old, consider replacing them with braided steel.
AnnualWipe the door gasket (front-loaders) thoroughly with a damp cloth. Debris and fabric softener residue collect in the folds of the seal and cause it to tear prematurely. Replacing a door seal is a repair that's easy to avoid entirely. Wiping it takes two minutes.
The mistake Kodiak sees most often: Too much detergent. Using more soap doesn't get clothes cleaner — it leaves residue in the drum, the pump, and the drain lines that causes clogs, excessive sudsing, and error codes. Use the manufacturer's recommended amount. With HE machines, use HE detergent only.
🧬 Dryer
The dryer has one job: move hot air through wet clothes. When anything blocks that airflow, the dryer works harder, takes longer, and eventually breaks — or becomes a fire hazard. The maintenance here is simple and non-negotiable.
Every LoadClean the lint trap before or after every single load. Every one. A partially blocked lint trap can increase drying time by 20–30% and dramatically increases fire risk. This is the single highest-return maintenance habit in your home.
MonthlyVacuum the lint trap slot with a narrow attachment. Lint gets past the screen and accumulates in the slot itself over time. It's not visible, but it's there.
MonthlyGo outside and check the dryer exhaust vent flap. It should open freely when the dryer is running and close when it's not. A stuck flap means warm, moist air is not escaping and cold air is getting in.
AnnualHave the dryer duct professionally cleaned if you have a duct run longer than 8 feet, or if your dryer is taking two or more cycles to dry a normal load. Lint accumulates in the duct bends and doesn't come out with household vacuums.
Honest Note from Kodiak
Dryer duct cleaning is one of the few maintenance services that actually has documented safety benefits, not just performance benefits. A clogged duct is one of the leading causes of house fires in Canada. We offer professional duct cleaning — but even if you don't book us, get it done somewhere, once a year.
🥥 Refrigerator
The fridge runs 24 hours a day, 365 days a year. It never gets a break. The least you can do is let it breathe properly and give its coils a fighting chance.
WeeklyDon't overfill the fridge. Air needs to circulate around your food to maintain even temperature. A jammed-full fridge makes the compressor work harder and causes uneven cooling — which often gets diagnosed as a "fridge problem" when it's actually a "too much food" problem.
MonthlyWipe the door gaskets (the rubber seals around all doors) with a damp cloth. A dirty or cracked gasket lets warm air in and cold air out, which forces the compressor to run constantly. Test the seal by closing the door on a piece of paper — it should have some resistance when you pull it out.
MonthlyMake sure there's at least 2–3 inches of clearance behind and on the sides of the fridge. Fridges need to exhaust heat. If they're crammed into a tight space with no airflow, they run hot and wear out early.
AnnualVacuum or brush the condenser coils. On most fridges, these are at the back or underneath behind a grille. Dusty coils reduce cooling efficiency significantly and are a leading cause of compressor failure. A can of compressed air or a coil brush does the job in 10 minutes.
AnnualIf your fridge has a water dispenser or ice maker, replace the water filter on schedule (usually every 6–12 months). A clogged filter reduces water flow, causes ice maker issues, and — less glamorously — stops filtering anything useful.
🍽 Dishwasher
A dishwasher that smells, doesn't clean properly, or leaves dishes spotted is almost always a maintenance issue, not a mechanical one. Five minutes a month keeps most of these issues from ever starting.
Every LoadScrape (don't rinse) dishes before loading. Modern dishwashers are designed to handle food particles — the sensors actually need some food residue to calibrate the wash cycle. Pre-rinsing wastes water and can confuse the machine into running a lighter cycle.
MonthlyRemove and rinse the filter. It's at the bottom of the tub, usually a twist-and-pull design. This is the #1 neglected dishwasher maintenance task. A clogged filter causes poor cleaning, standing water, and that signature "rotten" dishwasher smell.
MonthlyRun an empty cycle with a dishwasher cleaner tablet or a cup of white vinegar on the top rack. Clears grease, mineral scale, and detergent buildup from the spray arms and interior walls.
MonthlyCheck the spray arms for clogged holes. Pull them off (they usually just unscrew or pull up) and poke a toothpick through any blocked holes. Clogged spray arms cause uneven cleaning — top rack washed, bottom rack not, or vice versa.
AnnualCheck under the dishwasher for any signs of moisture or minor leaks. Small drips at the door seal or supply line connection often go unnoticed for months before causing floor or cabinet damage.
🔥 Stove & Oven
Stoves accumulate grease in places that are genuinely unpleasant to think about. Beyond the aesthetics, grease buildup is a fire risk and causes uneven heating that gets blamed on a faulty oven when the oven is actually fine.
WeeklyWipe the stovetop down after cooking, while it's still slightly warm (not hot). Grease and food residue that comes off easily when warm turns into a calcified mess once it's fully cooled and baked on through the next few cooking sessions.
MonthlyRemove burner grates and drip trays and soak them in hot soapy water. Replace them and put them back on once clean. This takes 20 minutes and prevents uneven heat distribution from blocked burner holes.
MonthlyCheck the oven door seal (the gasket around the oven cavity). A damaged or flattened seal lets heat escape and causes the oven to run cooler than the set temperature. If you're consistently adding extra time to recipes, this might be why.
AnnualRun the self-cleaning cycle if your oven has one. Once a year is enough — using it more frequently puts significant stress on the oven's components. Don't run it right before a big meal; it takes 3–4 hours and will heat up the kitchen considerably.
🔋 Microwave
The microwave is the most used appliance in most kitchens and the one people maintain the least, because it still technically works while covered in six months of splattered soup. It deserves better.
WeeklyWipe the interior — walls, ceiling, and the door's inner surface — with a damp cloth. Food splatter carbonizes over time and creates hot spots that cause uneven heating. More importantly, it smells.
WeeklyRemove the turntable and wipe the roller ring and the floor underneath it. Food collects there and creates burning smells that seem to have no source.
MonthlyIf you have an over-the-range microwave, clean the grease filter. It slides or clips out from the underside. Rinse it in warm soapy water and let it dry. A clogged grease filter reduces the ventilation fan's effectiveness dramatically.
AnnualCheck the door latch and seal. The microwave should not run if the door isn't fully closed. If you notice arcing, sparks, or the fan runs but heating feels weak, these are signs of internal component wear — worth having a tech take a look rather than ignoring.
❄ Freezer
MonthlyCheck for frost buildup. A thin layer is normal on manual-defrost models, but significant buildup (more than 1/4 inch) means the freezer is working harder than it needs to. Defrost it before the frost gets thick enough to insulate the coils.
MonthlyCheck the door seal the same way you do for the fridge — close the door on a piece of paper and see if it pulls out with resistance. A leaking freezer door is surprisingly common and causes the compressor to run continuously.
AnnualVacuum the condenser coils if accessible. Same reason as the fridge — dusty coils make the compressor work harder and fail sooner.
The Honest Part: Life Gets Busy
We know what you're thinking. You're going to bookmark this page, feel good about it, and then absolutely not clean your dryer duct in October like you planned. That's fine. You're not a bad person. You're a person with a job and a family and a dozen other things that need doing.
Here's what actually matters: the big-ticket habits. Clean the lint trap every load. Don't leave wet laundry sitting. Wipe the dishwasher filter. Those three things alone will prevent a surprisingly large percentage of the calls we get.
And when something does go wrong — because something always eventually goes wrong — don't panic. Most appliance repairs cost a fraction of what a replacement would, and most machines have years left in them even after a breakdown. A good tech can tell you within minutes whether the repair is worth it.
Why so many repairs aren't "part failures"
When a repair tech diagnoses a machine, there's often a moment of "the part is fine — this is a maintenance issue." Pumps clogged with debris. Motors overheated from blocked airflow. Circuit boards corroded from humidity in an unventilated space. These aren't manufacturing defects. They're the slow result of use patterns. The machine did what it was asked — just more of it, under worse conditions, than it was designed for. A little attention earlier would have changed the outcome.
Common Questions
How do I know if an appliance is worth maintaining vs. just replacing?
General rule: if the appliance is less than 10 years old and the repair cost is under 50% of what a comparable new unit would cost, repair and maintain. If it's older and breaking repeatedly, it may be time to move on. A good tech will give you an honest assessment — we'd rather you make the right call than spend money on a machine that's near end of life.
My dishwasher smells terrible even after I clean the filter. What else could it be?
Check the drain hose connection to the kitchen plumbing under the sink — food debris can accumulate right at the drain inlet and cause a persistent smell even when the machine itself is clean. Also check the door seal folds and the area around the drain basket. If all of that is clean and it still smells, the pump may have debris inside it — worth a service call.
How often should I actually get professional maintenance done on appliances?
For most appliances, the DIY checks in this guide are enough. The exception is dryer duct cleaning — that's genuinely worth having done professionally every 1–2 years if you have a long duct run. For everything else, a tech visit makes sense when something is acting up, not necessarily on a scheduled basis.
Is it true that overloading the washer causes real damage?
Yes. Overloading puts mechanical stress on the drum bearings, the motor, and the suspension. Over time this causes vibration, noise, and eventually bearing failure — one of the more expensive washer repairs. The rule of thumb is that you should be able to fit your hand in flat above the laundry in a top-loader, and a front-loader should be about 80% full at most.
