Why Is My Dishwasher Hot? The 5 Most Common Reasons And How To Fix Them!

A hot dishwasher can be a perplexing and concerning issue. While it’s normal for a dishwasher to generate some heat during operation, excessive heat can indicate an underlying problem. This blog post will delve into the potential causes of a hot dishwasher and provide step-by-step instructions for troubleshooting and resolving the issue.

Electrical Component Issues

Faulty Heating Element

The heating element is responsible for heating the water in the dishwasher. A faulty heating element can cause the dishwasher to overheat. Signs of a faulty heating element include:

• Dishwasher fails to heat water
• Dishwasher overheats
• Burning smell coming from the dishwasher

Faulty Thermostat

The thermostat controls the temperature of the water in the dishwasher. A faulty thermostat can cause the dishwasher to overheat or underheat. Symptoms of a faulty thermostat include:

• Dishwasher overheats
• Dishwasher fails to heat water
• Erratic water temperature

Mechanical Issues

Blocked Water Inlet Valve

A blocked water inlet valve can restrict the flow of water into the dishwasher. This can cause the dishwasher to overheat as the heating element tries to heat insufficient water. Signs of a blocked water inlet valve include:

• Dishwasher takes longer to fill
• Dishwasher fails to fill completely
• Dishwasher overheats

Faulty Drain Pump

The drain pump removes water from the dishwasher after the wash cycle is complete. A faulty drain pump can cause water to accumulate in the dishwasher, leading to overheating. Symptoms of a faulty drain pump include:

• Dishwasher fails to drain
• Water remains in the dishwasher after the wash cycle
• Dishwasher overheats

Other Potential Causes

Incorrect Water Temperature Setting

Some dishwashers allow you to adjust the water temperature setting. Using a higher water temperature setting can cause the dishwasher to overheat.

Overcrowding

Overcrowding the dishwasher can prevent water from circulating properly. This can lead to uneven heating and overheating.

Clogged Filter

A clogged filter can trap food particles and debris, which can obstruct the water flow and cause overheating.

Troubleshooting Steps

1. Check the electrical components: Inspect the heating element and thermostat for any visible damage or loose connections.
2. Check the water inlet valve: Ensure that the water inlet valve is not blocked by debris.
3. Check the drain pump: Listen for the sound of the drain pump running during the drain cycle. If you don’t hear any sound, the drain pump may be faulty.
4. Adjust the water temperature setting: If your dishwasher has adjustable water temperature settings, try lowering the temperature.
5. Avoid overcrowding: Load the dishwasher loosely to ensure proper water circulation.
6. Clean the filter: Regularly clean the dishwasher filter to remove food particles and debris.

When to Call a Professional

If you are unable to resolve the issue using the troubleshooting steps above, it is recommended to contact a qualified appliance repair technician. They can diagnose the problem accurately and perform the necessary repairs.

Wrapping It Up: The Importance of Timely Resolution

Ignoring a hot dishwasher can lead to further damage and potentially hazardous situations. By promptly troubleshooting and resolving the issue, you can ensure the safe and efficient operation of your dishwasher. Remember to follow the safety precautions outlined in your dishwasher’s user manual when performing any repairs.
