RINDGE, N.H. (MyKeeneNow) Proper dishwasher maintenance ensures optimal cleaning performance, extends appliance life, and prevents costly repairs. At Monadnock Appliance, our service technicians regularly see how simple maintenance routines prevent most dishwasher problems, making these practices essential for every household.
Understanding Your Dishwasher’s Filtration System
Modern dishwashers use filtration systems that require regular cleaning to maintain performance. The filter, typically located at the bottom of the tub, captures food particles and debris during wash cycles. A clogged filter restricts water circulation, leading to poor cleaning results and potential mechanical issues.
Check your filter monthly by removing the bottom dish rack and locating the cylindrical filter assembly.
Most filters twist out easily, allowing thorough cleaning under running water with a soft brush. Heavily soiled filters might require soaking in warm, soapy water to remove accumulated grease and debris.
Loading Techniques for Optimal Results
Proper loading significantly impacts cleaning performance and prevents damage to both dishes and dishwasher components. Face soiled surfaces toward spray arms, typically the center of the machine, ensuring water reaches dirty areas effectively. Avoid overcrowding, which restricts water circulation and spray arm movement.
Secure lightweight items that might flip over during washing, trapping water and creating spots or film.
Load cups and bowls at angles that promote proper drainage, preventing water from pooling in concave surfaces. Place tall items where they won’t block spray arm rotation or interfere with the upper rack’s movement.
Pre-rinse dishes only when necessary, as modern dishwashers and detergents are formulated to handle moderate food soils. Excessive pre-rinsing can actually reduce cleaning effectiveness by removing food particles that help activate enzyme-based detergents.
Detergent Selection and Usage
Use detergent specifically formulated for automatic dishwashers, as hand dishwashing liquids create excessive suds that can damage the machine. Powder, gel, and tablet detergents all work effectively when used properly, though tablets often provide the most consistent results.
Adjust detergent quantity based on water hardness and soil levels. Hard water requires more detergent for effective cleaning, while soft water needs less to prevent film formation. Many modern dishwashers include soil sensors that adjust cycle intensity, but proper detergent measurement remains important.
Rinse aid significantly improves drying performance and prevents water spots, especially in areas with hard water. Fill the rinse aid dispenser monthly and adjust the setting based on your water conditions and drying results.
Regular Maintenance Procedures
Clean the interior monthly using dishwasher cleaner or white vinegar to remove mineral deposits, grease, and soap residue. Run an empty cycle with two cups of white vinegar placed in a dishwasher-safe bowl on the top rack, followed by a cycle with baking soda sprinkled on the bottom to neutralize odors and remove stains.
Wipe down door seals and gaskets regularly to prevent mold and mildew growth. Check spray arms monthly for clogs, removing them if necessary to clear holes with a thin wire or toothpick. Clean the exterior and control panel with appropriate cleaners to maintain appearance and prevent damage.
Troubleshooting Common Issues
White film on dishes typically indicates hard water mineral deposits or excessive detergent use. Reduce detergent quantity and ensure rinse aid dispenser is filled and properly adjusted. Persistent filming might require professional water softening solutions.
Poor drying results often stem from improper loading, empty rinse aid dispenser, or blocked vents.
Ensure items don’t nest together, refill rinse aid, and check that nothing blocks the dishwasher’s drying vents.
