Usual Dishwasher Troubles and What to Do

1. Dishwasher Not Draining

A dishwasher that doesn’t drain properly can cause standing water and unpleasant odors. This issue is usually due to a clogged drain hose, filter, or garbage disposal. Regularly checking these components can prevent drainage problems.

Here’s what to do:

Inspect and Clean the Spray Arms

  • First, remove the spray arms and check for clogs.
  • Then, use a small brush or toothpick to clear any debris from the holes.
  • Finally, rinse the spray arms thoroughly and reinstall them.

Clean the Filter

  • Begin by locating the filter at the bottom of the dishwasher.
  • Next, remove the filter and rinse it under warm water, using a soft brush to remove any particles.
  • After cleaning, place the filter again and make sure it’s securely put in place.

Check the Water Temperature

  • Make sure your water heater is set to at least 120°F (49°C) for optimal cleaning.
  • If the water temperature is too low, adjust the settings accordingly.
  • Finally, run the dishwasher to see if cleaning performance improves.

2. Dishwasher Leaking

Leaking dishwashers can cause water damage and are often due to worn door seals, a faulty water inlet valve, or loose hose connections. We keep encouraging everyone to do regular inspections and also maintenance that can save you lots of money in the long run.

What to do? Here are our recommended troubleshooting tips:

Inspect the Door Seals

  • First, check the door seals for any signs of wear or damage.
  • If the seals are worn, replace them to ensure a proper seal.
  • Finally, close the door and run a cycle to check for leaks.

Check the Water Inlet Valve

  • Begin by inspecting the water inlet valve for any signs of leaks or damage.
  • If the valve is the culprit and has any sort of damage or is worn out, replace it with a new one.
  • Finally, run the dishwasher to ensure the leak is fixed.

Tighten Hose Connections

  • First, check all hose connections for tightness and signs of leaks.
  • If you find any loose connections, tighten them securely enough.
  • Finally, run a cycle to check for any remaining leaks.
