Why is my dishwasher not draining properly?

Why Isn’t My Dishwasher Draining Properly?

When your dishwasher isn't draining properly, leaving standing water at the bottom, several issues could be responsible:

• ✔ Clogged filter: The dishwasher's filter basket may be clogged with food particles.
• ✔ Blocked drain hose: The drain hose may be kinked or clogged.
• ✔ Clogged air gap: If your sink has an air gap, it might be blocked.
• ✔ Garbage disposal connection: If recently installed, the knockout plug in the disposal might not have been removed.
• ✔ Drain pump failure: The pump that forces water out might be malfunctioning.
• ✔ Clogged sink drain: The problem might be in your sink drain or further down the line.

Start troubleshooting by cleaning the filter at the bottom of the dishwasher, which is often the simplest solution. Next, check that the drain hose isn't kinked where it connects to the garbage disposal or sink drain. Also run your garbage disposal to clear any potential blockages, as many dishwashers drain through the disposal. For persistent issues, a professional plumber can diagnose and address more complex problems with the drain pump or internal components.

Proper water heater maintenance can extend its lifespan and improve efficiency. Here are key maintenance tasks:

For Traditional Tank Water Heaters:

• ✔ Annual flushing: Drain and flush your water heater annually to remove sediment buildup that reduces efficiency and shortens lifespan.
• ✔ Check the pressure relief valve: Test the temperature and pressure relief valve yearly to ensure it's functioning properly.
• ✔ Inspect the anode rod: Have the sacrificial anode rod checked every 2–3 years and replaced if significantly corroded.
• ✔ Check for leaks: Regularly inspect connections, the tank, and surrounding area for any signs of moisture or leaking.
• ✔ Maintain clearance: Keep the area around your water heater clear of items that could be fire hazards.

For Tankless Water Heaters:

• ✔ Descaling: Flush with a vinegar solution annually to remove mineral buildup (more frequently in areas with hard water).
• ✔ Clean the air intake filter: Check and clean the filter every 1–2 months.
• ✔ Inspect venting: Ensure venting remains unobstructed and in good condition.
