Does the Dishwasher Fill Slowly? Plumbing Supply Lines Kinks!

Does your dishwasher seem to take forever to fill up and run a normal wash cycle? It could be as simple as a clogged inlet screen restricting the flow of water. Typically, you will find a screen at the entrance to the supply hose coming into your dishwasher unit. Water contains rust, pipe wall corrosion, calcium and lime deposits, minerals and sediment commonly found in all water, either from a well or a municipal source.

The second thing to do is to check all the supply hoses for kinks, twists or damage. If you notice any water or signs of a leak, address the problem before it causes severe damage. Silent supply line leaks will lead to mold and mildew, foul odors and damage to wooden cabinets, floors and walls.

In this dishwasher plumbing tip series, we look at the most common dishwasher plumbing problems, possible causes, and share some insight on diagnosing dishwasher’s that either leak or stop draining.

If Your Dishwasher is not Draining Properly Try These Tips!

Some water remaining in the bottom of your dishwasher when it completes the entire wash cycle is normal. If your dishwasher is not draining properly there are a few things you can try. If you open the door when the dishwasher has completed and water runs out you could have a bad dishwasher door gasket, although this is rare unless your appliance is an older model.

There are a lot of connections under the busiest sink in the house and that is why kitchen drains remain one of the most complicated plumbing systems. When a garbage disposer unit is tied into the kitchen sink and it becomes full it could prevent proper draining. Turn on and continue a steady stream of water when engaging the garbage disposer. Continue running cold water for an additional 30 seconds. This could correct the problem, and remember to run your unit regularly for best results.

Dishwasher Tips from our Plumbing Team

Taking some preventative steps to keep your dishwasher running smoothly can help you avoid annoying dishwasher drain issues:

To clear the standing water remaining in the bottom of your dishwasher, line the floor with towels or newspaper and use a plastic cup to scoop out the water into a bucket. When the water becomes too shallow, soak up the remaining moisture with an absorbent cotton towel to completely get it dry.

Always make sure that you’re using the right type of dish detergent per manufacturer’s directions, to avoid clogging the drain.

Load the dishwasher per the suggested instructions provided in the manual for your specific machine for best results. Here is a short list of other possibilities:

  • Check the drain hose connecting to the sink and garbage disposal. If there are any kinks, try and straighten them out. Make sure the hose seal is tight.
  • Find the drain basket, located at the side or bottom of the appliance for hardened detergent or food particles which can sometimes be responsible for clogs. Simply wash the basket free of debris and replace it.
  • Listen to your machine while it’s running. Is it making a humming sound or a clicking noise? Anything other than the usual operating sounds could be a clue that something is possibly wrong with the drain pump or motor.
