Diagnosing the Issue

Before diving into any repair work, it’s crucial to diagnose the issue with your dishwasher knob accurately. Incorrect diagnosis may not only waste your time but could also result in unnecessary expenses for parts or services that you don’t need.

1.1 Unplug the Dishwasher

The very first thing you should do is disconnect the dishwasher from its power source for safety reasons. To do this, locate the dishwasher’s electrical cord and unplug it from the outlet. If your dishwasher is hardwired to your home’s electrical system, you’ll need to shut off the circuit breaker responsible for the dishwasher.

1.2 Examine the Knob

With the dishwasher safely unplugged, it’s time to closely examine the knob. Look for signs of physical damage such as cracks, chips, or deformities. If you find any visible damage, there’s a good chance the knob will need to be replaced. Use a flashlight if necessary to get a clearer view.

2.1 Replace the Knob

If you’ve determined that the knob is damaged, the next course of action is straightforward: replace it. A damaged knob won’t engage properly with the timer motor, causing it not to advance. First, pull off the damaged knob from its stem. You may need to wiggle it gently to loosen it.

Identify the model number of your dishwasher, usually found on the inside edge of the door or the back of the machine. Search online or visit a home appliance store to find a replacement knob that is compatible with your dishwasher model. Install the new knob by simply pushing it onto the stem. Make sure it fits securely.

Plug the dishwasher back in, or turn the circuit breaker back on, and test the knob to see if it advances as it should.

2.2 Check the Timer Motor

If the knob itself appears fine, the issue may be related to the timer motor. The timer motor is responsible for advancing the knob during the dishwasher cycle. Here’s how you can check the timer motor:

Open the dishwasher’s control panel, usually located at the top of the door. You may need a screwdriver to remove screws holding it in place.

Locate the timer motor inside the control panel. It’s often a small cylindrical or rectangular piece connected to the knob’s stem.

Using a multimeter set to the resistance setting (often denoted by the Ω symbol), place the test probes on the motor’s terminals.

If the multimeter shows infinite resistance or no continuity, the timer motor is faulty and will need to be replaced.
