Preventive Maintenance Guide | SmartTech Appliance Repair Dallas

🫧

Washing Machine

Recommended lifespan: 10-14 years

Monthly

Run a cleaning cycle with washer cleaner or white vinegar
Wipe down the door seal and remove lint buildup
Clean the detergent drawer with warm water
Leave the door open after each use to prevent mold

Every 3-6 months

Check and clean the drain pump filter
Inspect hoses for cracks or bulging
Check that the machine is level
Clean under and behind the machine

Yearly

Replace inlet hoses if older than 5 years
Check water pressure — too high can damage valves
Inspect the drum for rust or damage

Pro tip: Always use HE (High Efficiency) detergent in front-load washers. Regular detergent creates too many suds and can damage the drum bearings over time.

Dryer

Recommended lifespan: 10-13 years

Every use

Clean the lint trap before every cycle
Never run the dryer without the lint screen
Don't overload — clothes need room to tumble

Every 3 months

Clean the lint trap slot with a vacuum
Inspect and clean the exhaust duct
Check the exterior vent flap opens properly
Wipe the drum interior with a damp cloth

Yearly

Professional duct cleaning — prevents fire risk
Check and clean the moisture sensor bars
Inspect the drum belt for wear

Warning: A clogged dryer vent is the #1 cause of home dryer fires in the US. If your dryer takes more than one cycle to dry clothes, the vent is likely clogged — call us right away.

Refrigerator

Recommended lifespan: 13-17 years

Monthly

Clean door gaskets with warm soapy water
Check that door seals are airtight (paper test)
Clean the drip pan under the fridge
Keep temperature between 35-38°F

Every 6 months

Vacuum the condenser coils (back or bottom)
Replace the water filter if you have an ice maker
Clean the ice maker and water dispenser
Pull out fridge and clean behind it

Yearly

Inspect door hinges and adjust if needed
Check the defrost drain for clogs
Verify the freezer temperature is 0°F

Stove / Oven

Recommended lifespan: 13-15 years

After every use

Wipe down burners and stovetop when cool
Clean spills immediately to prevent baking on
Replace drip pans when stained or warped
