Finding standing water in your dishwasher can be alarming. Before doing anything else, check that there’s no blockage in your filter; food particles and wet paper from container labels could clog it. Filters typically feature a cage or grille cover.
If your filter and air gap are clear, check the drain hose connected to the sink or garbage disposal for signs of obstruction or kink. It could be filled with dirt or have become bent.

Clogged Spray Arm
Occasionally, your dishwasher’s spray arms- those long propeller-blade-like parts that encase and spin inside its tub- may become clogged with gunk and prevent any water from draining away properly. A toothpick or paperclip may help clear away debris; alternatively, soak the arm in soapy water mixed with one cup of vinegar to soften hardened debris.
If your spray arm still doesn’t turn freely or your drain hose doesn’t drain as expected, or if the drain pipe appears blocked with debris such as porcelain chips, plastic fragments, or broken pieces of garbage disposal pipe, it may be time to inspect its drain pipe for possible clogging.
If you suspect a clog, disconnect the power to the dishwasher, drain its hose, and clean it thoroughly. Referring to your user manual for instructions is highly recommended while using a multimeter to test continuity in its valve is also helpful.
The dishwasher drain hose connects from the disposal to the sink’s air gap, but sometimes food debris in either of these places prevents water from reaching it. When this occurs, running cold water through the garbage disposal may help clear it away and restore proper drainage of its contents.
If this doesn’t solve the issue, try unplugging and inspecting your disposal for possible blockages by shining a flashlight into its opening and fishing out any obstructions with pliers. Be mindful not to break or puncture the drain hose while inspecting for broken circuit breakers that might have come loose within.
Regular cleaning of your garbage disposal drain opening and surrounding plumbing is recommended to avoid clogs. Fats, oils, and other solid waste can easily clog disposal, leading to foul smells and blocked sinks. To prevent this from happening, run fats and oils under hot and cold water before placing them in your garbage disposal.
Your dishwasher’s long propeller-blade-like parts may become clogged with food particles and cause pooled water in its tub, leading to water pooling. To clear these out safely and without power interruptions, simply use a toothpick or paperclip – but always turn it off before proceeding! Additionally, ensure the air gap cylinder (if applicable) is clean.
Drain hoses may also be to blame, particularly if they become kinked or folded against your sink or dishwasher cabinet. Look for it where it connects to the garbage disposal and air gap – usually near where it connects to the garbage disposal – although its location can differ. Use a flexible drain snake or homemade flush with baking soda and vinegar (caustic chemicals can damage hoses).
If none of these approaches resolve your dishwasher issues, it may be time to bring in professionals. An appliance repair specialist can assess and replace faulty components; or, in extreme cases, recommend purchasing a new model.
Most dishwasher issues stem from issues with the drain pump, drain hose, or air gap. The drain hose connects the pump to either garbage disposal or an air gap (more on this later), flushing dirty water away from the dishwasher. Be sure to inspect this hose regularly for signs of wear and ensure it is unclogged or kinked for optimal functioning.
Consult your owner’s manual for where and how to disconnect a hose; once disconnected, it should be checked for blockages by blowing or pushing a wire hanger through it – if the hose is blocked, it must be replaced immediately.
If your hose and disposal are clear and the removal doesn’t seem clogged up, the cause could be an electrical problem with your solenoid. Although homeowners shouldn’t attempt this repair themselves, professional plumbers can usually fix it. If the issue continues, additional components like motherboard or timer replacement may need to be made, requiring professional assistance to access and remove.
