Answers from 17+ years of appliance repair experience in Port St. Lucie
Why is my dishwasher not cleaning dishes properly?+
A clogged filter is the #1 cause of poor dishwasher cleaning. Remove and clean the filter under hot water. Other causes: blocked spray arms, low water temperature (needs 120°F minimum), incorrect loading that blocks water flow, or using the wrong detergent. In Port St. Lucie, hard water mineral buildup also reduces cleaning performance. Clean the filter and spray arm holes monthly. Treasure Coast Appliance Repair diagnoses dishwasher issues same-day.
Why is my dishwasher not draining?+
A dishwasher that won't drain has a clogged drain filter, a blocked drain hose, a failed drain pump motor, or a clogged garbage disposal connection (the air gap or disposal knockout plug). Clean the bottom filter first — most drainage issues are caused by food debris in the filter basket. If the filter is clear, the drain pump or hose needs professional attention. Repair cost: $80–$250.
Why is my dishwasher leaking water?+
Dishwasher leaks come from a worn door gasket (the #1 cause of front leaks), a cracked or loose door latch, a faulty water inlet valve, over-sudsing from wrong detergent, or a damaged tub. Check the door gasket for cracks or debris preventing a seal. Gasket replacement costs $80–$150. Water inlet valve replacement costs $100–$180.
Why is my dishwasher not starting?+
Check the door latch first — dishwashers won't start unless the door is fully latched and the latch switch engages. Then check the power (breaker and outlet) (the door switch must engage), check for a child lock setting, and try a reset (unplug for 5 minutes). If none of these work, the door latch, control board, or thermal fuse has failed. Call Treasure Coast Appliance Repair at (772) 353-5791.
Why does my dishwasher leave dishes cloudy or spotted?+
Cloudy dishes are caused by hard water mineral deposits (very common in Port St. Lucie), low rinse aid levels, too much detergent, or etching from overly aggressive wash cycles on delicate glassware. Use rinse aid consistently, reduce detergent amount, and try a citric acid wash cycle to remove mineral buildup. Permanent etching (rough to the touch) cannot be reversed.
Why does my dishwasher smell bad?+
Dishwasher odors come from trapped food debris in the filter, drain hose, or door gasket folds. Clean the bottom filter (remove and scrub with a brush), wipe the door gasket edges, and run an empty cycle with a cup of white vinegar or a dishwasher cleaner tablet on the hottest setting. In Florida's humidity, monthly cleaning is essential to prevent bacteria and mold.
Why is my dishwasher making a grinding noise?+
Grinding noises indicate food debris caught in the chopper blade or wash impeller, a failing wash pump motor, a loose spray arm hitting dishes, or broken glass trapped in the sump area. Remove the bottom spray arm and filter to check for debris. If the grinding is from the motor, the wash pump needs replacement — $150–$300 at Treasure Coast Appliance Repair.
Why is my dishwasher not filling with water?+
A dishwasher that starts but doesn't fill has a faulty water inlet valve (most common), a stuck or failed float switch (the small dome on the tub floor), low water pressure, or a kinked supply line. Verify the water supply valve under the sink is fully open. Inlet valve replacement costs $100–$180. Float switch replacement costs $60–$100.
Why does my dishwasher leave food particles on dishes?+
Food particles remaining on dishes after a cycle mean the spray arms are clogged, the filter is dirty, the wash pump is weakening, or you're overloading and blocking spray patterns. Remove spray arms and clean the nozzle holes with a toothpick — hard water deposits clog them. Also clean the filter under running water. These are the two most common fixes.
Why does my dishwasher leak from the bottom?+
Bottom leaks indicate a cracked tub, a leaking wash pump seal, a damaged water inlet valve, or a loose hose clamp on the drain or supply line. These leaks are often intermittent and hard to spot until significant water accumulates. Turn off water supply and schedule a diagnostic — Treasure Coast Appliance Repair identifies leak sources precisely.
Why won't my dishwasher door close properly?+
A dishwasher door that won't latch has a misaligned door latch, a bent or worn hinge, a warped tub (from heat), or a dish rack that's out of alignment and preventing full closure. Check that the racks are properly seated and nothing is protruding past the tub edge. Latch adjustment or replacement costs $60–$120.
Why is my dishwasher running too long?+
Modern dishwashers can run 2–3 hours on normal cycles — this is by design for energy efficiency (uses less water, more time). If your cycle is significantly longer than usual, the water temperature may be too low (the dishwasher heats water to the target temp before proceeding), the turbidity sensor may be detecting dirty water and extending the wash, or the control board is malfunctioning.
Why does my dishwasher stop mid-cycle?+
Mid-cycle stops are caused by a faulty door latch that loses contact, an overheating motor, a clogged drain triggering overflow protection, a failed thermal fuse, or a control board error. Check for error codes on the display. If the dishwasher stops and the drain pump runs continuously, there's likely a water leak activating the flood sensor.
Why is there standing water in the bottom of my dishwasher?+
A small amount of water at the bottom is normal — it keeps the pump seals lubricated. If there's an inch or more, the drain is clogged. Check the filter for food debris, ensure the drain hose has a high loop (prevents backflow from the disposal), and run the garbage disposal to clear any shared drain blockage.
Why does my dishwasher leave a white film on dishes?+
White film is mineral deposits from hard water — extremely common in Port St. Lucie. Solutions: use rinse aid at the maximum setting, try a detergent with built-in water softener, run an empty cycle with 2 cups of white vinegar monthly, and consider a water softener for your home. This is a water quality issue, not a dishwasher malfunction.
Why is my dishwasher not drying dishes?+
Energy-efficient dishwashers use condensation drying (no heating element), so dishes come out slightly damp — this is normal, not a malfunction. Improve drying by using rinse aid (essential for drying), selecting the heated dry option if available, opening the door slightly after the cycle ends, and running the hot water at the kitchen sink before starting the dishwasher.
Why does my dishwasher trip the circuit breaker?+
A dishwasher tripping the breaker signals a short circuit in the heating element, motor, or wiring. This is a safety hazard — stop using the dishwasher and call Treasure Coast Appliance Repair. Do not repeatedly reset the breaker. Common causes: a grounded heating element touching the tub, or water leaking onto electrical components.
Why is my dishwasher door falling open?+
A door that drops open or won't stay closed has worn or broken door springs, hinges, or door cable. The springs/cables counterbalance the door weight. Over time, springs stretch and cables fray. Spring replacement costs $60–$120. Hinge replacement costs $80–$150. These are quick repairs for our technicians.
Why does my dishwasher have mold?+
Mold grows in dishwashers when moisture is trapped in the door gasket folds, filter area, and spray arm joints. Florida's humidity accelerates mold growth. Clean the gasket with a vinegar solution monthly, remove and scrub the filter, and leave the door slightly ajar between cycles to allow air circulation. Run a hot sanitize cycle with bleach (no dishes) to kill mold spores.
Why does my dishwasher rust inside?+
Interior rust indicates the protective coating on the dish racks or tub interior is damaged. Rack tine tips lose their vinyl coating over time, exposing bare metal. Fix rack rust with vinyl rack repair paint ($8). Tub rust may indicate a crack — if water leaks through, the tub needs replacement. Salt air near the Treasure Coast accelerates dishwasher rust.

How much does dishwasher door gasket replacement cost?+

How much does dishwasher pump replacement cost?+
Dishwasher wash pump or drain pump replacement costs $150–$300 depending on which pump and the brand. Drain pumps are less expensive ($150–$200).
