What To Know

  • Check if the power cord is securely plugged into an outlet and that the circuit breaker or fuse hasn’t tripped.
  • If the water flow is weak or nonexistent, contact a plumber to inspect the water lines or valves.
  • The door latch may not be engaged securely, the water supply may be inadequate, or there may be a power issue.

A malfunctioning dishwasher can disrupt your daily routine and leave you with a pile of dirty dishes. If you’re facing this issue, don’t fret! This comprehensive guide will provide you with an in-depth understanding of how to check if your dishwasher is working and resolve any problems you encounter.

Step 1: Check for Power

Begin by ensuring that your dishwasher has power. Check if the power cord is securely plugged into an outlet and that the circuit breaker or fuse hasn’t tripped. If necessary, reset the breaker or replace the fuse.

Step 2: Inspect the Water Supply

Verify that your dishwasher has an adequate water supply. Open the hot water tap near the dishwasher and check for a strong flow of hot water. If the water flow is weak or nonexistent, contact a plumber to inspect the water lines or valves.

Step 3: Examine the Drain Hose

Ensure that the drain hose is not kinked, clogged, or obstructed. The drain hose should be properly connected to the sink drain or garbage disposal and should be clear of any debris or blockages.

Step 4: Test the Door Latch

The door latch plays a crucial role in ensuring that the dishwasher operates safely. Open and close the dishwasher door several times to check if the latch engages securely. If the door doesn‘t latch properly, the dishwasher won’t start.

Step 5: Inspect the Spray Arms

The spray arms rotate and spray water onto the dishes. Over time, they can become clogged with food particles and mineral deposits. Remove the spray arms and inspect them for any blockages or damage. Clean them thoroughly with a soft brush or a vinegar solution.

Step 6: Check the Filter

The filter collects food particles and debris to prevent them from clogging the pump and drain. Locate the filter at the bottom of the dishwasher and remove it. Clean the filter thoroughly with warm water and a dishwashing detergent solution.

Step 7: Run a Diagnostic Cycle

Many modern dishwashers have a built-in diagnostic cycle that can help identify potential problems. Refer to your dishwasher’s user manual to determine if it has a diagnostic cycle and follow the instructions to run it.
