Dishwasher Not Doing Heated Dry

Step-by-step Troubleshooting Guide

Here are the steps to troubleshoot…

Step 1: Check Your Dishwasher Settings

The first step in diagnosing why your dishwasher is not doing a heated dry is to check its settings. It’s not uncommon for settings to be accidentally changed, whether it’s by a curious child, a cleaning mishap, or even an unintended press of a button.

Before diving into more technical troubleshooting, it’s wise to ensure that the settings are configured correctly.

Locating the Settings Panel

Open your dishwasher door to reveal the control panel, which is usually located on the front face or the top edge of the door.

Take a moment to familiarize yourself with the various buttons and options available. You should see labels or icons that indicate each button’s function.

Checking the Heated Dry Option

Look for a button or a knob labeled “Heated Dry,” “Dry Heat,” or something similar. This is the control that activates the heated dry function. The exact name can vary depending on the brand and model of your dishwasher.

Press the button or turn the knob to the “On” position to activate the heated dry function. You may hear a click or see a light indicator come on, confirming that the setting is activated.

Running a Test Cycle

Once you’ve ensured that the heated dry option is activated, close the dishwasher door.

Select a short wash cycle for testing purposes—there’s usually an option for a “Quick Wash” or “Rinse Only” cycle.

Start the dishwasher and allow it to run through the selected cycle.

At the end of the cycle, carefully open the dishwasher and check the dryness of your dishes. If they are dry, you’ve likely solved the problem.

Step 2: Inspect the Heating Element

If you’ve checked the settings and your dishwasher is still not doing a heated dry, the next logical step is to examine the heating element.

This crucial component is what actually generates the heat needed to dry your dishes. If it’s not working correctly, your dishwasher won’t be able to complete the dry cycle as expected.

Safety First: Disconnect the Power

Before you proceed with any internal inspections, it’s essential to disconnect your dishwasher from the power source for safety reasons.

Locate your dishwasher’s power cord and unplug it from the electrical outlet. If your dishwasher is hardwired, you’ll need to switch off the circuit breaker that controls its power supply.

Wait for a few minutes to make sure that all residual power is drained from the machine.

Locating the Heating Element

Open the dishwasher door and remove the bottom dish rack to clear your workspace.

Look towards the base of the dishwasher. You’ll see a circular or semi-circular metal loop. This is the heating element.

You’ll need to check your manual for specific steps to access the heating element in your dishwasher model.

Conducting a Visual Inspection

Inspect the heating element closely for any signs of physical damage. You’re looking for discoloration, burns, or cracks in the metal. Any of these could indicate a malfunctioning heating element.

If your heating element has a coil, make sure it’s not broken or deformed, as this could also be a sign that it’s not working properly.

What to Do If You Find Damage

If you find that the heating element is damaged, you’ll likely need to replace it. It’s generally not recommended to attempt a repair yourself, as this is a complex component that interacts with various other parts of the dishwasher.

Note down your dishwasher’s model number, found usually on a label on the side of the door or at the back of the machine.

Purchase a replacement heating element that is compatible with your dishwasher’s model. You can usually find this through the manufacturer’s website or a trusted appliance parts retailer.

Step 3: Check the Thermostat

If you’ve ruled out settings and the heating element as potential culprits and your dishwasher is still not doing a heated dry, it’s time to focus on the thermostat.

This often-overlooked component is vital because it regulates the temperature inside your dishwasher, ensuring that it’s hot enough to dry your dishes but not so hot as to damage them.

Safety Measures

Before you start, remember to ensure that the dishwasher is disconnected from the power source. This is an essential safety step that should never be overlooked when working on electrical appliances.

Locating the Thermostat

Open the dishwasher door and remove any racks or items that may obstruct your access to the bottom of the machine.

The thermostat is generally located near the bottom of the dishwasher, often close to the heating element. It’s usually a small, round device connected with wires.

How to Test the Thermostat

To test the thermostat, you’ll need a multimeter, a device that can measure electrical continuity. If you don’t own one, they are widely available from hardware stores and online retailers.

Set your multimeter to the lowest setting for Ohms (resistance).

Attach the multimeter’s probes to the thermostat’s terminals. You’re checking for continuity, which means that electrical current should be able to flow through the thermostat freely.

A reading of zero or close to zero indicates good continuity, while a reading that doesn’t change or goes to infinity suggests that the thermostat is faulty.

What to Do If Your Thermostat is Faulty

If the multimeter test shows that the thermostat is faulty, it’s time to replace it. Note down your dishwasher’s model number if you haven’t done so already.

Use this model number to purchase a compatible thermostat. This part is generally available on the manufacturer’s website or from reputable appliance parts dealers.

While it’s possible to replace the thermostat yourself if you’re comfortable with moderate DIY tasks, hiring a professional is a good idea if you’re not confident about handling electrical components.

Step 4: Examine the Timer and Control Board

If you’ve checked all the previous components and your dishwasher is still not doing a heated dry, the timer and control board are the next elements to investigate.

These components are the “brains” behind your dishwasher’s operation, governing the cycles and ensuring everything runs as it should. A malfunction here could disrupt multiple processes, including the heated dry cycle.

Safety Comes First

As always, safety is paramount. Make sure your dishwasher is disconnected from the power source before proceeding to open any panels or handle internal components.

Locating the Timer and Control Board

The timer and control board are generally located within the door panel of your dishwasher or at the top of the unit behind a removable cover.

Use a screwdriver to remove screws that secure the panel, being careful to note how everything fits together for reassembly.

Performing a Visual Inspection

Once you have access to the timer and control board, look for any obvious signs of wear, damage, or burned areas. These could be indications of a problem.

Check for loose or disconnected wires as these could also cause the heated dry cycle to malfunction. In some cases, you might spot a blown fuse; this would also signify a need for replacement.

Please note that specific steps to access and replace damaged parts in your dishwasher will vary widely depending on the model of your machine. Check your manual for more specific information.

When to Replace the Timer and Control Board

If your visual inspection reveals signs of damage or wear, it’s a strong indicator that one or both components need to be replaced.

As with previous components, note down the model number of your dishwasher. This ensures that any replacements you purchase will be compatible with your machine.

While some people with electrical know-how may opt to replace these parts themselves, given the complexity and vital role these components play, hiring a professional technician for diagnosis and replacement is often the most prudent choice.

Step 5: When to Contact a Professional

If you’ve diligently followed each of the preceding steps and your dishwasher is still not doing a heated dry, it might be time to acknowledge that the problem could be beyond a simple DIY fix.

While it’s commendable to try and solve issues on your own, there’s no shame in seeking professional help when needed. In fact, doing so can sometimes be more cost-effective in the long run, as professionals can diagnose and fix multiple issues in one go.

Search for technicians who specialize in dishwasher or general appliance repairs. You can usually find reputable professionals through online reviews or recommendations from friends and family.

Ensure the technician you choose is certified and insured for the work they’ll be doing. Don’t hesitate to ask for a quote or an estimate upfront. Many professionals will offer this, and it gives you an idea of what the repair will cost.

What to Expect During the Visit

The technician will likely start with their own diagnostic tests to confirm the issue. This can include using specialized tools to measure electrical flow, water temperature, and other factors.

Based on their findings, they will recommend a course of action. This could range from replacing a single component to suggesting more extensive repairs or even replacing the unit if it’s old and not cost-effective to fix.

Making the Final Decision

After receiving professional advice, it’s up to you to decide how to proceed. Whether you opt for a repair or decide it’s time to invest in a new dishwasher, you’ll be making an informed choice, grounded in professional expertise.
