1. Check Dishwasher Settings

Before diving into more advanced troubleshooting methods, it’s crucial to make sure your dishwasher settings aren’t the reason behind the lack of hot water. Some dishwashers have eco-friendly settings that aim to conserve energy by skipping the heating cycle.

Step-by-Step Guide

Open the Dishwasher: Pull open the dishwasher door to access the control panel.

Check Your User Manual: Each dishwasher model is a bit different. Refer to your user manual to get a clearer understanding of what each setting does. Look for cycles that include a heating element.

Select a Cycle That Uses Heat: On the control panel, select a washing cycle known to use hot water. This is usually labeled as “High Temp,” “Sanitize,” or something similar.

Run a Test Wash: Close the door and start a test wash cycle. Allow it to run for a few minutes and then pause it to open the door and feel the water. It should be getting hot by now.

If changing the setting solves the problem, then you can sigh in relief. If not, you’ll need to proceed to more technical solutions.

2. Test the Heating Element

The heating element is responsible for raising the water temperature inside your dishwasher. A faulty one can cause your dishwasher not to get hot.

Step-by-Step Guide

Unplug the Dishwasher: Always prioritize safety. Unplug your dishwasher from the electrical socket to eliminate the risk of electric shock.

Locate the Heating Element: Open the dishwasher and locate the heating element. It’s usually a circular tube-like structure at the base of the machine.

Use a Multimeter: Set your multimeter to the lowest setting for ohms and touch the probes to the terminals. A reading between 15 and 30 usually indicates a functioning element.

No Continuity?: If the multimeter shows no continuity, the heating element is defective and needs to be replaced.

If the heating element is the culprit, replacing it should solve the problem. If it tests fine, proceed to the next step.


3. Check the Thermostat

The thermostat is responsible for maintaining the water temperature. If it’s faulty, this could be why your dishwasher is not getting very hot.

Step-by-Step Guide

Unplug the Dishwasher: Safety first! Make sure the dishwasher is unplugged from the electrical socket.

Locate the Thermostat: Open the dishwasher and locate the thermostat. It’s usually situated near the heating element.

Test with a Multimeter: Set your multimeter to test for continuity and touch its probes to the thermostat terminals.

Replace if Defective: If the multimeter shows no continuity, it’s a sign the thermostat is defective and needs to be replaced. If replacing the thermostat solves the issue, you’re all set. Otherwise, continue to the next troubleshooting step.

4. Inspect the Timer

The timer or control board governs the various cycles in your dishwasher, including the heating cycle. A malfunctioning timer could prevent your dishwasher from getting hot.

Step-by-Step Guide

Locate the Timer: The timer is generally located behind the control panel at the top of your dishwasher door.

Inspect for Physical Damage: Look for signs of wear, fraying, or burning on the timer. These can indicate that it’s time to replace it.

Replace if Necessary: If you notice any signs of damage or if you’ve tested the other components and they appear to be functioning correctly, the timer may need to be replaced. Replacing a faulty timer should resolve issues related to cycle control, including heating problems.

Important Note: Please keep in mind that specific steps to access and replace damaged components will vary widely depending on the model of your appliance. Check your product manual for more specific information.
