Dishwasher is one of the essential appliances that you need in a commercial kitchen. Rather than employing people to wash dishes manually in your restaurant, you can choose to buy a commercial dishwasher to ensure more speed and efficiency. These appliances only take anywhere between one to four minutes to thoroughly clean your dishes and are a great way to reduce the manual labor needed to wash a large number of dishes. However, like any appliance, dishwashers aren’t perfect and especially in the long run, if routine maintenance is not done then these appliances could develop problems. Relying on commercial kitchen maintenance programs which include cleaning, descaling of water use equipment, and calibration of cooking equipment can help extend the life of such appliances.
Some dishwasher concerns can be fixed easily with a few do-it-yourself tricks and then it may not require a visit from a technician. Here is a look at some of the common dishwasher problems and ways to tackle them:

  1. Dishes coming out dirty
    Dirty dishes could come out from a dishwasher if

    • You have overloaded your machine
    • A utensil is restricting the spinning motion on any of the spray arms
    • You loaded the plates without scraping food off them first
    • There is grease, debris, or blockages in the strain screen and door gasket
    • There is dirt or funk in spray arms

    To clean the spray arms, remove the arms and gently clean them with a toothbrush and a pipe-cleaner. Once you put them back, try running a clean cycle, and see if your dishes come out better.

  2. Residue on dishes
    If your dishes come out covered in water spots or with a white residue on them, then it may be because:

    • The water from the dishwasher may be staying on your dishes too long. The solution is to give a simple rinse aid.
    • Check the dishwasher salt and fill it up if you need to.
    • Make sure the dishwasher salt cap is screwed on properly.
  3. White or cloudy glasses
    • A common cause of cloudy glassware is hard water, so try using a water softener or a (hard water/regular) detergent, to soften your water.
  4. Dishwasher leaks onto the floor
    This is one of the most dreaded dishwasher problems that can even cause serious damage to your home. All you have to do is:

      • Check for any cracks, damage, or large debris on your dishwasher door and door gasket, that could be preventing the door from sealing completely and do the needful.
      • Check for any damage on the drainage hose
      • Check for any defective pump or pump seal, if necessary change out the seal or replace the pump.

    According to DIGITAL TRENDS, the mechanism that indicates your dishwasher’s water level, the float switch, may be stuck in the down position, which could also cause your machine to overfill and leak onto the floor. So, check your float switch and if it’s stuck, clean it and remove the thing that’s preventing it from functioning properly.

  5. Dishes aren’t properly dried at the end of the cycle
    This is a common problem that occurs due to the dishwasher’s heating element.

    • Using a multi-meter, check the heating element to make sure it is working properly.
    • If the heating element is in working order, check your high limit thermostat.
    • Moreover, make sure your rinse aid dispenser is not empty. If it is, then your dishes will not dry as easily. So, check the rinse aid and fill it up.

    Make sure you don’t take things out until the program has completely run.

  6. Incomplete wash cycles or it takes too long
    A problem likely with the timer motor, thermostat, or heating element.

    • Check all with a multi-meter
  7. Dishwasher not draining properly
    • If the drain hose is entangled, the water cannot run properly into the machine and makes draining difficult. Make sure that a portion of the drain hose is at least 0.5m above the dishwasher’s enclosure floor.
    • Avoid or remove the blockage of the filter system by cleaning once a week regularly.
