Dishwasher Cleaning — What’s Actually Hiding Inside Your Machine
The Bosch Dishwasher was leaving spots on all the glasses. I thought it was because of the rinse agent. But then I realized there was an awful smell after each washing, and dirty greasy dishes. Turns out that for eight months I haven’t cleaned the dishwasher filter. One proper deep clean later, the machine ran like new. That’s the thing about kitchen appliance cleaning the appliance doing the cleaning needs cleaning too.
Most people assume soap and hot water running through a machine means it stays clean. Not at all. Food debris, fat, minerals, and soap scum will accumulate on all parts in the dishwashing machine’s filter mechanism, spray arm openings, seals, interior surfaces, and drain hose. Not cleaning them out will cause the machine to smell bad, give dirty glassware and greasy dishes, and finally result in poor washing.
Reasons Why Dishwasher Maintenance Is Not Done
The truth is that the dishwasher does look clean on the surface. You open it after every cycle, and it is fine for a bit. However, the filter captures the food debris during every cycle. The door seal retains the moisture along with the food remnants. Holes of the spray arm become clogged up due to the accumulation of calcium and magnesium from the hard water. All these facts remain hidden until the dishwasher lets you know about them via cloudiness and foul odor of the dishes.
Routine dishwasher maintenance takes under 20 minutes a month. That’s the trade-off: 20 minutes of dishwasher cleaning routine versus a $200+ repair service call when something clogs the dishwasher pump or drain hose beyond DIY reach. The math is obvious.
Dishwasher Parts You Need to Know Before You Start Cleaning
The Filter, Spray Arms, and Door Gasket Do the Most Work
Before starting the first wash cycle, know your way around. Dishwasher filters are located at the base of the tub, typically below the lower arm of the sprayer. They trap any food particles each time a washing is performed. A clogged dishwasher filter is the number-one cause of a dirty dishwasher and a smelly dishwasher in the same household.
The upper spray arm and lower spray arm distribute water across every load. Blocked spray arm holes mean uneven water distribution which explains why dishes on one side of the rack come out dirty. The door gasket, that rubber door seal running around the inside edge of the door, holds moisture and food residue in its folds. It’s where mold in dishwasher situations almost always start.
Detergent tray, soap dispenser, rinse aid storage section, and salt holder require cleaning on a regular basis. The heating component that is located at the bottom of the tub may form deposits of limescale over time, especially when using hard water. It is essential to know the names of all parts in order to understand the instructions on how to clean the dishwasher properly.
How to Clean Dishwasher Filter Step by Step
The Most Important and Most Ignored Part of Dishwasher Care
Pull out the bottom rack completely. Look at the base of the dishwasher tub. The drain filter is usually a twist-off cylinder turn it counterclockwise and lift it out. Some models have a flat mesh filter underneath as well remove that too.
Rinse the filter using hot running water. Scrub off the food deposits and grease from the filter with a brush. In case any lime scale forms on the mesh filter, dip the filter in distilled white vinegar for about 10-15 minutes and then clean it. Vinegar is good at removing minerals and it will not harm the mesh fabric.
Once it’s clean, lock it back into position firmly. A loose filter lets debris bypass it entirely and reach the dishwasher pump which is a much harder fix than a clean filter. Dishwasher filter needs to be cleaned once in 3 to 6 months if dishwasher is used frequently. In case dishes aren’t scraped prior to loading, then clean it once in a month. Whirlpool advises cleaning it once in a month.
How to Clean Dishwasher Spray Arms Without Special Tools
Blocked Holes Are Why Your Dishes Come Out Still Dirty
What’s wrong with my dirty dishes even after the dishwashing machine has finished its process? It usually happens because of the clogged holes on the spray arm.Food, calcium, and iron can become lodged in the tiny openings from which water squirts out.
The bottom spray arm must be removed; in most dishwasher models, this can easily be accomplished by either pulling it straight upward or removing a center cap. Put it in the sink and run some water on it. Using a toothpick, clean out each hole that is clogged. The toothpick method may not sound fancy, but it really works. In case of limescale deposits, soak the spray arm in white vinegar for 20-30 minutes before poking out each hole.
Do the same with the upper spray arm. Reinstall both before running any cleaning cycle. This one step fixes most cases of cloudy dishes, cloudy glasses, and food residue on dishes that people blame on their detergent. The dishwasher cleaning steps most people skip filter and spray arms account for 80 percent of performance problems.
How to Deep Clean Dishwasher Naturally — The Vinegar and Baking Soda Method
The Two-Step Cleaning Method That Actually Works
This is the most searched dishwasher cleaning hack for good reason. White vinegar and baking soda operate in different ways; the effectiveness of the two-step cleaning process is achieved by performing the two processes in a sequence. The effects of both substances will cancel out when they are combined. Make sure that you don’t use the two substances at once.
Start off by ensuring that the dishwasher is empty. Add 1 cup of white vinegar to a dishwasher safe cup and put the cup into the dishwasher’s top rack. The vinegar should not be poured directly in the base of the dishwasher or the detergent dispenser. Let the vinegar slosh around during the wash cycle. Use the highest heat setting for the longest wash cycle.
Once that cycle has been completed, spread 1 cup baking soda evenly inside the bottom of the dishwasher. Use the shortest cycle using hot water. The baking soda cycle removes any smell of the vinegar, absorbs any odor, scrubbing away any food particle build-up and polishing the interior surfaces of the dishwasher.
This is how to deep clean dishwasher naturally without any commercial products. It costs almost nothing and handles the majority of routine deep cleaning cycle needs in under two hours.
When to Add Citric Acid Cleaning Instead
Citric acid cleaning is the stronger alternative for how to remove limescale from dishwasher interiors, especially in UK and European homes where hard water UK dishwasher problems are more severe. Bicarbonate of soda dishwashing powder is called baking soda in the USA; it is one and the same product and one and the same process.
Pour 1 cup of citric acid into a dishwasher-safe vessel and place it on the top rack of your dishwasher. Run it on a hot program with no dishes in it. Citric acid is quicker at dissolving lime scale build up compared to vinegar and it does not have any odour. It is the recommended way of decalcifying dishwasher parts in hard water areas.
How to Clean Dishwasher Door Gasket and Interior Door Lip
Where Mold and Bacteria Growth Actually Live
The rubber door seal is the breeding ground most people forget. Run a paper towel along the inside folds of the door gasket after any deep clean and see what comes off. It’s almost always brown-gray buildup a mix of food residue, mold, and bacteria growth that the cleaning cycles never reach directly.
Make a baking soda paste by mixing the baking soda with water. Use an old toothbrush as the toothbrush scrubbing technique is the only way to really get into the folds and apply the paste to every corner of the rubber door seal. Clean off using a damp all-purpose cleaning cloth. For information about how to remove mold from dishwasher seals, wipe the gasket down with undiluted distilled white vinegar on a microfiber cloth first, then allow it to rest for five minutes before scrubbing with the baking soda paste.
The interior door lip that narrow ledge when the door is fully open collects grime nobody sees. Wipe it down every cleaning session. It’s consistently the dirtiest surface in the machine.
After cleaning the door gasket, leave the door open after cycle finishes. Air dry dishwasher by leaving the door propped for several hours. Moisture trapped inside after cycles is what feeds mold growth and mildew dishwasher problems over time. Should you leave dishwasher door open after cycle? Yes every time.
Cleaning a Smelly Dishwasher – Identifying The Odor Source
Why Does My Dishwasher Smells Like Rotten Eggs?
There are only three sources of that smelly rotten eggs odor in the dishwasher: dirty drain filter holding decomposed food scraps, standing water in the dishwasher because of a clogged drain, or a garbage disposal connection problem. Garbage disposals and dishwashers are connected through a common drain hose in most cases. Run the garbage disposal prior to starting the dishwasher to clear up that garbage disposal connection cleaning issue that repair guides ignore.
A musty odor from your dishwasher indicates mold or mildew growth under the door gasket or near the drain cover. Hard water causes sulfur or metallic smell dishwasher that becomes stronger while using the appliance without proper descaling dishwasher process.
How To Prevent Dishwasher Smelling? Cleaning the drain filter, wiping down the door gasket, unclogging the spray arms and then running the vinegar/baking soda trick separately will help you fix the odor issue in the majority of cases. In case of persistent odors from dishwasher after cleaning, put a bowl of lemon juice or several lemon peels on the top rack and run a short hot cycle.
