How to Clean Dishwasher Filter

How to Clean Dishwasher Filter?

All dishwashers have one or more filters in place during the process to remove food particles from the wash water. It’s extremely important to keep your dishwasher filter clean. Some filters are generally self-cleaning but these filters can become clogged under certain water conditions.

It’s the job of the filter to keep bits of food from recirculating on dishes, pots, silverware, and the like after they’ve been washed away by the water and detergent. But that hard-working aspect of the machine must be buildup-free to do its job.

How to Remove Dishwasher Filter?

If you’re having issues with your dishwasher, it might be time to clean the filter. The dishwasher filter is responsible for trapping food particles and debris that are left behind after a wash cycle. Over time, these particles accumulate and can cause clogs or other problems in your appliance. Luckily, removing and cleaning the filter is a quick and easy process.

Before you start, make sure to turn off your dishwasher and disconnect it from its power source. Locate the filter – this is typically found at the bottom of your appliance, near the spray arm. Some dishwashers have a removable cover over the filter, while others require you to twist or unscrew it in order to remove it.

Once you’ve accessed the filter, gently lift it out of its housing. You’ll likely see food particles or other debris trapped inside – simply use a soft brush or cloth to scrub away any buildup.

Why do you Need to Clean the Dishwasher Filter?

You need to clean the dishwasher filter on a weekly basis as it stops food waste that has become stuck in the tank from ending up on your dishes. Under the kitchen sink tap, the inner filters can be washed with a soft brush. The outer metal filter only needs hot water rinsing.

If your dishwasher is 10 years old or older, it probably has a self-cleaning filter. Over the past decade, dishwasher manufacturers have moved away to quieter manual-clean filters from that type, which is often equipped with a grinder.

Both types work well but they work differently. The biggest difference is that regular cleaning of a manual filter is required.

If you are replacing your dishwasher on the market, you can note that most of the new models have manual-clean filters. Buy a modern dishwasher that has the best features and specifications.

When do you need to Clean the Dishwasher Filter?

To experience your dishwasher’s performance at its peak, you should periodically clean your dishwasher’s filter. Clean dishwasher filter ASAP when you experience the following circumstances:

  • When cleaning efficiency drops on a significant level.
  • When you see soil or other objects on the Upper Filter Assembly.
  • Remove the lower dish rack to access the dishwasher filter. Find the filter in the bottom of the tub back corner, or around the bottom of the spray arm base. Some dishwashers have a triple filter system with two parts:

  • The upper filter assembly keeps excessively large items and foreign objects out of the pump along with very fine food particles.
  • The lower filter prevents the food from recirculating onto your plates.
  • Self Cleaning Filters vs Manual Cleaning Filters

    Self-cleaning filter dishwashers rely on an integrated grinder to pulverize food such as garbage disposal, which is then washed away through the drain. These filters are referred to as “self-cleaning,” since the owner has no routine buildup to manage. The downside of this feature is that such dishwashers tend to be significantly louder than those with manual filters.

    Depending on the usage and pre-rinse habits, manual filters require cleaning at least once per month. Also, you should be alert to visual and olfactory signs – such as dishes that feel gritty, stray bits of food left behind, or unpleasant odors to remind you to clean the filter.

    How to clean your Dishwasher Filter

    We recommend that you clean your filter after regular intervals to get optimum results. If you don’t know how to clean your dishwasher filter, then you can follow these simples steps:

    Step One:

    Remove the dishwasher’s bottom rack and locate the filter on the unit’s floor. The filter is a cylindrical tube that twists-locks into place. Many versions also have a lower alternative, a smooth filter located underneath the cylindrical one.

    This filter has a hole in the middle that covers the cylindrical tube, and it does not lock in place. Both need to be removed in order to clean.

    Step Two:

    To unlock first remove the upper, cylindrical filter by twisting. The filter bends counter-clockwise in most versions, but arrows will show the right direction. Pull up softly until unlocked to remove the filter. If there is any lower filter then simply lift it out.

    Step Three:

    Hand-wash the filter(s) under running water in warm, soapy water and rinse thoroughly. For persistent food items, clean the filter with a sponge or old toothbrush quite gently. Then, check the region where the filters for errant food particles are located, using a damp towel to wipe the area clean if required.

    Step Four:

    Place the flat filter back in place, if any, then insert the cylindrical filter next, locking it back in place securely.

    With the process of cleaning the dishwasher filter as fastly and easily, you may still have time to spare to clean the hard-working appliance in full or at least add a reminder in your calendar to schedule a one-to-two-month cleaning out. While, for its next load of dirty dishes, the appliance is prepared, so you can fill up the dishes.

    How to reinstall your Dishwasher Filter after Cleaning

    You can reinstall your dishwasher filter after cleaning easily by following the method shared below:

    • Noting the previous descriptions, place the Lower Filter in the bottom of the dishwasher under the Locating Tabs, so that the round opening for the Upper Filter Assembly lines up with the round opening at the bottom of the tub.
    • Insert the Upper Filter Assembly into the Lower Filter circular opening.
    • Rotate the filter slowly in the clockwise direction until it drops in. Continue rotating until the filter is locked in. If the filter is not fully seated, keep turning the filter in the clockwise direction until it drops and locks.

    Do not operate your dishwasher without properly installed filters to avoid dishwasher damage. Make sure the Lower Filter is in place securely and the Upper Filter Assembly is locked in place. If the Upper Filter Assembly turns around freely, it is not locked in.
